GCN Circular #15728
E. Troja (NASA/GSFC/UMCP), A. P. Beardmore (U Leicester), M. G. Bernardini (INAF-OAB), D. N. Burrows (PSU), V. D'Elia (ASDC), P. A. Evans (U Leicester), D. Malesani (DARK/NBI), F. E. Marshall (NASA/GSFC), A. Maselli (INAF-IASFPA), P. T. O'Brien (U Leicester), K. L. Page (U Leicester), D. M. Palmer (LANL) and M. H. Siegel (PSU) report on behalf of the Swift Team:
At 11:57:40 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140114A (trigger=583861). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 188.482, +27.926 which is
```
   RA(J2000) = 12h 33m 56s
   Dec(J2000) = +27d 55' 35"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peaked structure with a duration of at least 300 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~118 sec after the trigger.
The XRT began observing the field at 11:59:46.0 UT, 126 seconds after the BAT trigger. Using promptly downlinked data we find a fading, uncatalogued X-ray source with an enhanced position: RA, Dec 188.5214, 27.9514 which is equivalent to:
```
   RA(J2000)  = 12h 34m 05.13s
   Dec(J2000) = +27d 57' 05.1"
```
with an uncertainty of 2.6 arcseconds (radius, 90% containment). This location is 155 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper.
A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (1.55 x 10^20 cm^-2, Kalberla et al. 2005), with an excess column of 3.1 (+3.20/-2.63) x 10^21 cm^-2 (90% confidence).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 120 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.02.
Burst Advocate for this burst is E. Troja (eleonora.troja AT nasa.gov). 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/too.html.)
GCN Circular #15729
S. B. Cenko (NASA/GSFC) reports on behalf of a larger collaboration:
We imaged the location of GRB140114A (Troja et al., GCN 15728) with the robotic Palomar 60 inch telescope. Observations were obtained in the r=E2= =80=99, i=E2=80=99, and z=E2=80=99 filter beginning at 12:01 UT on 2014 January 14 (~ 3 minutes after the Swift trigger). The seeing was relatively poor throughout the observations (~ 3=E2=80=9D).
We do not detect any emission at the location of the XRT counterpart. Using several nearby point sources from SDSS for reference, we calculate the following upper limits in coadded images:
```
i=E2=80=99 > 20.8 mag at a mean epoch of dt ~ 14 min
r=E2=80=99 > 21.2 mag at a mean epoch of dt ~ 15 min
z=E2=80=99 > 20.0 mag at a mean epoch of dt ~ 16 min
```

We observed the field of GRB 140114A (Troja et al., GCN 15728) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astron=F3mico Nacional on Sierra San Pedro M=E1rtir from 2014/01 14.50 to 2014/01 14.56 UTC (9.6 to 90.6 minutes after the BAT trigger), obtaining a total of 0.98 hours exposure in the r and i bands and 0.43 hours exposure in the Z, Y, J, and H bands.
For a source within the Swift-XRT error circle, in comparison with the SDSS DR9 and 2MASS, we obtain the following detections:
```
  r     21.92 +/- 0.10
  i     21.31 +/- 0.07
  Z     21.14 +/- 0.12
  Y     20.75 +/- 0.15
  J     20.56 +/- 0.12
  H     20.28 +/- 0.15
```
These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB.

Using 2514 s of XRT Photon Counting mode data and 1 UVOT images for GRB 140114A, 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 = 188.52173, +27.95080 which is equivalent to:
```
RA (J2000): 12h 34m 5.22s
Dec (J2000): +27d 57' 02.9"
```
with an uncertainty of 1.9 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).

WeiKang Zheng, Alexei V. Filippenko, Adam Morgan (UC Berkeley), and S. B. Cenko (NASA/Goddard Space Flight Center) report on behalf of the KAIT GRB team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to Swift GRB 140114A (Troja et al., GCN 15728) starting at 12:01:57 UT, 257 s after the burst. Observations were performed with an automatic sequence in the I and clear (roughly R) filters, and the exposure time was 20 s per image. Within the enhanced XRT error circle (Beardmore et al., GCN 15733), we do not detect the afterglow reported by Butler et al. (GCN 15732) in our single images, nor in a co-added image from the first 5 images. The typical limiting magnitude of our single clear image is about 19.4. The co-added image limiting magnitude is 20.6 at a mean time of about 490 s after the burst.

M. De Pasquale (UCL-MSSL) and E. Troja (NASA/GSFC/UMCP) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 140114A 120 s after the BAT trigger (Troja et al., GCN Circ. 15728). No optical afterglow consistent with the XRT position (Beardmore et al. GCN Circ. 15733) is detected in the initial UVOT exposures and following summed exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first finding chart (FC) exposure and subsequent exposures are:

Using the data set from T-239 to T+963 sec from recent telemetry downlinks, we report further analysis of BAT GRB 140114A (trigger #583861) (Troja, et al., GCN Circ. 15728). The BAT ground-calculated position is RA, Dec = 188.498, 27.942 deg, which is
```
   RA(J2000)  =  12h 33m 59.6s 
   Dec(J2000) = +27d 56' 31.9" 
```
with an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment). The partial coding was 100%.
The mask-weighted light curve shows one roughly symmetrical peak starting at ~T+10 sec, peaking at ~T+100 sec, and ending at ~T+210 sec. There are a few small peaks riding on top of the main peak. T90 (15-350 keV) is 139.7 +- 16.4 sec (estimated error including systematics).
The time-averaged spectrum from T+24.2 to T+202.5 sec (with 2.7 sec missing in the middle due to data drop outs) is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 2.06 +- 0.09. The fluence in the 15-150 keV band is 3.2 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+115.88 sec in the 15-150 keV band is 0.9 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

V. Mangano (PSU), M.C. Stroh (PSU), P.A. Evans (U. Leicester), B.P. Gompertz (U. Leicester), J.P. Osborne (U. Leicester), B. Sbarufatti (INAF-OAB/PSU), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC), D.N. Burrows (PSU) and E. Troja report on behalf of the Swift-XRT team:
We have analysed 11 ks of XRT data for GRB 140114A (Troja et al. GCN Circ. 15728), from 118 s to 24.7 ks after the BAT trigger. The data comprise 449 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 15733).
The late-time light curve (from T0+5.0 ks) can be modelled with a power-law decay with a decay index of alpha=0.50 (+/-0.15).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.22 (+/-0.03). The best-fitting absorption column is 1.53 (+/-0.07) x 10^21 cm^-2, in excess of the Galactic value of 1.6 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 2.33 (+0.21, -0.20) and a best-fitting absorption column of 1.3 (+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 3.1 x 10^-11 (4.8 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     1.3 (+0.5, -0.4) x 10^21 cm^-2
Galactic foreground: 1.6 x 10^20 cm^-2
Excess significance: 4.5 sigma
Photon index:	     2.33 (+0.21, -0.20)
```
If the light curve continues to decay with a power-law decay index of 0.50, the count rate at T+24 hours will be 0.020 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 6.2 x 10^-13 (9.6 x 10^-13) erg cm^-2 s^-1.

T. Guver (Istanbul Univ.), F. V. Ferrante (SMU), R. Kehoe (SMU), G. Dhungana (SMU), and W. Zheng (UC Berkely) report on behalf of the ROTSE GRB team:
ROTSE-IIIb, located at McDonald Observatory, Texas, responded to GRB 140114A (Swift trigger 583861; Troja et al, GCN 14728), producing images beginning 22.4 s after the GCN notice time. An automated response took the first image at 11:59:20.4 UT, 98.1 s after the burst, under fair conditions. We took 10 5-sec, 10 20-sec and 9 60-sec exposures. These unfiltered images are calibrated relative to USNO A2.0 (R). Imaging is on going.
Comparison to the DSS (second epoch) reveals no new sources within the 3-sigma Swift/BAT error circle or the XRT error circle; the field is not crowded. Individual images have limiting magnitudes ranging from 14.0-15.1; we set the following specific limits.

We observed the field of GRB 140114A (Troja et al., GCN 15728) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astron=F3mico Nacional on Sierra San Pedro M=E1rtir from 2014/01 15.32 to 2014/01 15.55 UTC (19.72 to 25.20 hours after the BAT trigger), obtaining a total of 3.36 hours exposure in the r and i bands and 1.48 hours exposure in the Z, Y, J, and H bands.
The optical/NIR source detected by RATIR last night (Butler et al., GCN 15732) has now faded below our detection limit. In comparison with the SDSS DR9 and 2MASS, we obtain the following upper limits (3-sigma):
```
  r     > 23.67

Z. Cano (U. Iceland), D. Xu, D. Malesani (DARK/NBI), P. Jakobsson (U Iceland), T. Pursimo (NOT) report on behalf of a larger collaboration:
We observed the field of GRB 140114A (Troja et al., GCN Circ. 15728) with the 2.5-m Nordic Optical Telescope (NOT) equipped with ALFOSC starting at 03:19 UT on 15-Jan-2014. We obtained 12x300 s frames in SDSS-i at a mean time of 15.93 hr after the burst.
The afterglow is clearly detected in the stacked image at coordinates:
```
RA: 12:34:05.1
Dec: +27:57:02.6
```
with an uncertainty of 0.5''. This position is 1.4'' from the enhanced XRT position (Beardmore et al., GCN Circ. 15733), and falls within the enhanced XRT error circle. This is presumably the source detected by Butler et al. (GCN Circ. 15732). The afterglow has m(i)=23.19+/-0.16 AB at 15.93 hr post-burst, calibrated with the nearby SDSS stars and not corrected for foreground extinction.
