GCN Circular #24806
The Fermi GBM team reports the detection of a likely LONG GRB
At 10:47:00 UT on 13 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190613B (trigger 582115625.049376 / 190613449).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 305.4, Dec = -11.6 (J2000 degrees, equivalent to J2000 20h 21m, -11d 35'), with a statistical uncertainty of 3.2 degrees.
The angle from the Fermi LAT boresight is 60.0 degrees.
The skymap can be found here: http://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2019/bn190613449/quicklook/glg_skymap_all_bn190613449.png

GCN Circular #24807
A. D'Ai (INAF-IASFPA), E. Ambrosi (INAF-IASFPA), V. D'Elia (SSDC), J.D. Gropp (PSU), N. J. Klingler (PSU), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL) and M. H. Siegel (PSU) report on behalf of the Neil Gehrels Swift Observatory Team:
At 10:47:02 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 190613B (trigger=908329). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 305.422, -4.664 which is
```
   RA(J2000) = 20h 21m 41s
   Dec(J2000) = -04d 39' 49"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a complex structure with a duration of about 15 sec. The peak count rate was ~2500 counts/sec (15-350 keV), at ~1 sec after the trigger.
The XRT began observing the field at 10:48:39.5 UT, 97.5 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 305.4294, -4.6461 which is equivalent to:
```
   RA(J2000)  = 20h 21m 43.06s
   Dec(J2000) = -04d 38' 46.0"
```
with an uncertainty of 4.8 arcseconds (radius, 90% containment). This location is 69 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy.
The initial flux in the 2.5 s image was 4.90e-09 erg cm^-2 s^-1 (0.2-10 keV).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 105 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at
```
  RA(J2000)  =	20:21:43.65 = 305.43189
  DEC(J2000) = -04:38:47.9  =  -4.64665
```
with a 90%-confidence error radius of about 0.62 arc sec. This position is 9.2 arc sec. from the center of the XRT error circle. The estimated magnitude is 17.76 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.07.
Burst Advocate for this burst is A. D'Ai (antonino.dai AT inaf.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/)
GCN Circular #24808
J. Burgess, F. Kunzweiler, B. Biltzinger, F. Berlato, & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 582115625 at 10:47:00 on 13 June 2019 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60).
The best-fit position (1 sigma statistical errors) is:
```
RA(2000.0) = 302.8+/-2.3 deg
Decl.(2000.0) = -8.2+/-2.7 deg
```
We estimate an additional systematic error of 1 deg.

A.P. Beardmore, P.A. Evans, M.R. Goad and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team.
Using 2078 s of XRT Photon Counting mode data and 6 UVOT images for GRB 190613B, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 305.43206, -4.64686 which is equivalent to:
```
RA (J2000): 20h 21m 43.69s
Dec (J2000): -04d 38' 48.7"
```
with an uncertainty of 1.7 arcsec (radius, 90% confidence).
This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).

E. Bissaldi (Politecnico & INFN Bari), O.J. Roberts (USRA/NASA) and C. Meegan (UAH) report on behalf of the Fermi GBM Team:
"At 10:47:00.05 UT on 13 June 2019, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 190613B (trigger 582115625 / 190613449), which was also detected by the Swift/BAT (D'Ai et al. 2019, GCN 24807) The GBM on-ground location is consistent with the Swift position.
The angle from the Fermi LAT boresight at the GBM trigger time using the Swift-BAT position is 59 degrees.
The GBM light curve consists of single bright peak with a duration (T90) of about 5 s (50-300 keV). The time-averaged spectrum from T0-1 s to T0+4 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.96 +/- 0.05 and the cutoff energy, parameterized as Epeak, is 334 +/- 35 keV.
The event fluence (10-1000 keV) in this time interval is (4.4 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+2 s in the 10-1000 keV band is 7.5 +/- 0.3 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html

F. E. Marshall (NASA/GSFC) and A. D'Ai (INAF-IASFPA) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 190613B 106 s after the BAT trigger (D'Ai et al., GCN Circ. 24807). A source consistent with the enhanced XRT position (Beardmore et al. GCN Circ. 24812) is detected in the initial UVOT exposures.
The preliminary UVOT position is:
```
    RA  (J2000) =  20:21:43.66 = 305.43191 (deg.)
    Dec (J2000) = -04:38:48.0  =  -4.64666 (deg.)
```
with an estimated uncertainty of 0.43 arc sec. (radius, 90% confidence).
Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are:

WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on behalf of the KAIT GRB team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to the Swift GRB 190613B (D'Ai et al. GCN 24807) starting at 2311s after the burst. Observations were performed with a sequence in the clear (roughly R), V, and I filters, and the exposure time was 20 s per image. We detected the optical afterglow at the reported Swfit/UVOT position (D'Ai et al., GCN 24798; Marshall & D'Ai, GCN 24817) in clear band image. We estimate the clear band magnitude to be ~19.3 at 2321s after the burst.

Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 190613B (trigger #908329) (D'Ai et al., GCN Circ. 24807). The BAT ground-calculated position is RA, Dec = 305.434, -4.655 deg which is
```
   RA(J2000)  =  20h 21m 44.2s
   Dec(J2000) = -04d 39' 17.0"
```
with an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment). The partial coding was 18%.
The mask-weighted light curve shows a main pulse structure that starts at ~T-3 s, peaks at ~T0, and ends at ~T+2 s. In addition, there are some weak emissions that lasts until ~T+175 s. T90 (15-350 keV) is 160.84 +- 16.83 sec (estimated error including systematics).
The time-averaged spectrum from T-2.85 to T+175.42 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.84 +- 0.24. The fluence in the 15-150 keV band is 2.3 +- 0.3 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+0.01 sec in the 15-150 keV band is 5.7 +- 0.7 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

K.L. Page (U. Leicester), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), A. Melandri (INAF-OAB), P. D'Avanzo (INAF-OAB), A. Tohuvavohu (PSU), S. J. LaPorte (PSU), J.A. Kennea (PSU) and A. D'Ai report on behalf of the Swift-XRT team:
We have analysed 6.3 ks of XRT data for GRB 190613B (D'Ai et al. GCN Circ. 24807), from 103 s to 19.3 ks after the BAT trigger. The data comprise 352 s in Windowed Timing (WT) mode with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Beardmore et al. (GCN Circ. 24812).
The late-time light curve (from T0+5.3 ks) can be modelled with a power-law decay with a decay index of alpha=0.52 (+/-0.11).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 1.93 (+/-0.05). The best-fitting absorption column is 3.28 (+0.24, -0.23) x 10^21 cm^-2, in excess of the Galactic value of 6.0 x 10^20 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 1.90 (+/-0.11) and a best-fitting absorption column of 2.6 (+0.5, -0.4) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.8 x 10^-11 (5.2 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     2.6 (+0.5, -0.4) x 10^21 cm^-2
Galactic foreground: 6.0 x 10^20 cm^-2
Excess significance: 7.6 sigma
Photon index:	     1.90 (+/-0.11)
```
If the light curve continues to decay with a power-law decay index of 0.52, the count rate at T+24 hours will be 0.091 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 3.5 x 10^-12 (4.8 x 10^-12) erg cm^-2 s^-1.

We observed the field of GRB 190613B (D’Ai et al. GCN 24807, Burgess et al. GCN 24808, Beardmore et al. GCN 24812, Bissaldi et al. GCN 24814, Marshall et al. GCN 24817, Zheng & Filippenko GCN 24818, Ukwatta et al. GCN 24820, Page et al. GCN 24823) using STANCAM, mounted on the 2.5m Nordic Optical Telescope, at Roque de los Muchachos Observatory (La Palma, Spain). The observations consisted of 3x300s imaging in R-band and 5x200s in z-band. Observations started on 14 June at 2:50 UT (16.05 hr after the burst). The optical counterpart is well detected in both bands at an estimated R(Vega) = 21.8+/-0.2 mag, as compared to field stars from the Nomad catalogue.

The 60cm BOOTES-5/JGT robotic telescope at Observatorio Astronomico Nacional in San Pedro Martir (Mexico) automatically responded to the Swift trigger of GRB 190613B (D'Ai et al., GCNC 24807). The first image (1s exposure, clear-filter) was obtained at 10:48:04.16 UT (i.e. 62s post-burst). We detect the optical afterglow at the position reported by Swift (Beardmore et al. GCNC 24812, Marshall et al. GCNC 24817) with R = 16.1. A sequence of images was obtained and the analysis is on going. The magnitude is calibrated against the USNO-B1 catalog and is not corrected for Galactic extinction in the direction of the GRB.
We thank the staff at Observatorio Astronomico Nacional in San Pedro Martir for its excellent support.

At 2019-06-13T10:47:00.00 (T0), Insight-HXMT/HE detected GRB 190613B (trigger ID: HEB190613449) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #24806) and Swift/BAT (D'Ai et al. 2019, GCN #24807).
The Insight-HXMT/HE light curve mainly consists of two pulses with a duration (T90) of 3.59 s measured from T0-0.56 s. The 1-ms peak rate, measured from T0+2.09 s, is 2847 cnts/sec. The total counts from this burst is 6013 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB190613449_lc.jpg
All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 keV (deposited energy). Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope.
Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS). More information about it could be found at: http://www.hxmt.org.

P. Schady (Uni. Bath) and J. Bolmer (MPE Garching) report:
We observed the field of GRB 190613B (Fermi trigger 582115625.049376/190613449; GCN #24806, Swift trigger 908329; D'Ai et al., GCN #24807) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at ESO La Silla Observatory (Chile).
Observations started at 09:18 UT on 14 June 2019, 22.4 hrs after the GRB trigger. They were performed at an average seeing of 1.4" and at an average airmass of 1.2.
We detect a single point source in our g'r'i'z'JH images consistent with the reported GRB optical and X-ray afterglow (Beardmore et al., GCN #24812, Marshall et al., GCN #24817). Based on a total 22 min exposure in g'r'i'z' and 22 min in JHK, we estimate the following preliminary magnitudes (all in Vega system):
```
g' = 22.79 +/- 0.05 mag
r' = 22.05 +/- 0.04 mag
i' = 21.56 +/- 0.05 mag
z' = 21.15 +/- 0.07 mag
J = 20.5 +/- 0.1 mag
H = 20.2 +/- 0.2 mag
K > 19.8 mag
```
Given magnitudes are calibrated against PanStarrs as well as 2MASS field stars and are not corrected for the expected Galactic foreground extinction corresponding to a reddening of E_(B-V)=0.06 mag in the direction of the burst (Schlafly & Finkbeiner 2011).
We thank the observer astronomer at the MPG 2.2m in La Silla for their help in obtaining these data.

V. Cunningham (U of Maryland), J. D. Neill (Caltech), S. B. Cenko
(NASA GSFC), and R. Walters (Caltech) report on behalf of the
SEDM team:
We observed the optical counterpart to GRB 190613B (D'Ai et al. GCN 24807)
with the Spectral Energy Distribution Machine (SEDM) on the 60 inch
telescope at Palomar Observatory. The SEDM is a low resolution (R ~ 100)
integral field unit spectrometer with a multi-band (ugri) rainbow camera imager
(see Blagorodnova et al. 2018, PASP, 130, 035003, and Rigault et al. 2019,
astro-ph/1902.08526).
The SEDM began observing the optical counterpart at 11:00:28 UTC (11.79
minutes after the burst trigger time). We performed an 1800 s exposure over
the wavelength range 3800-9200 A. We tentatively identify an absorption
feature at ~ 5385 A that is consistent with the Mg II 2796,2803 doublet at z =
0.92. However, due to the relatively low significance of the feature and the
lack of corroborating lines, we cannot confirm this redshift currently. The
continuum emission is well-fit by a power law spectrum with index alpha = 0.09
(f_nu ~ nu^-alpha).

D. Svinkin, S. Golenetskii, R. Aptekar, D. Frederiks, M. Ulanov, A. Tsvetkova, A. Lysenko, A. Kozlova, and T. Cline on behalf of the Konus-Wind team, report:
The long-duration GRB 190613B (Swift-BAT detection: D'Ai et al., GCN Circ. 24807; Fermi-GBM observation: Bissaldi et al., GCN Circ. 24814; Insight-HXMT/HE detection: Luo et al., GCN Circ. 24829) triggered Konus-Wind at T0=38825.774 s UT (10:47:05.774).
The burst light curve shows a single pulse which starts at ~T0-2.6 s and has a total duration of ~4 s. The emission is seen up to ~3 MeV.
As observed by Konus-Wind, the burst had a fluence of 3.48(-0.79,+1.29)x10^-6 erg/cm2, and a 64-ms peak flux, measured from T0+0.544 s, of 2.65(-1.10,+1.54)x10^-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range).
The time-averaged spectrum of the burst (measured from T0 to T0+8.448 s) is best fit in the 20 keV - 4 MeV range by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -0.93(-0.53,+0.83) and Ep = 277(-107,+331) keV (chi2 = 82/72 dof). Fitting by a GRB (Band) model yields the same alpha and Ep, and an upper limit on the high energy photon index: beta < -1.8 (chi2 = 82/71 dof).
The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB190613_T38825/
All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.

Analysis of AstroSat CZTI data showed the detection of a long GRB 190613B, which was also detected by Fermi GBM (GCN #24806), Swift detection (D'Ai A. et al., GCN #24807), BALROG (Burgess J. et al., GCN #24808), Swift-XRT (Beardmore A.P. et al., GCN #24812), Swift-BAT (Ukwatta T.N. et al., GCN #24820), Insight-HXMT/HE (Luo Q. et al., GCN #24829) and Konus-Wind (Svinkin D. et al., GCN #24844).
The source was clearly detected in the 40-200 keV energy range. The light curve shows multiple pulses of emission with the strongest peak at 10:47:02.5 UT. The measured peak count rate associated with the burst is 439 cts/s above the background in the combined data of four quadrants, with a total of 1298 cts. The local mean background count rate was 654 cts/s. Using cumulative rates, we measure a T90 of 11.75 s.
It was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range.
CZTI GRB detections are reported regularly on the payload site at http://astrosat.iucaa.in/czti/?q=grb. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC and PRL. The Indian Space Research Organisation funded, managed and facilitated the project.
