GCN Circular #8804
H. A. Krimm (CRESST/GSFC/USRA), S. D. Barthelmy (GSFC), A. P. Beardmore (U Leicester), D. N. Burrows (PSU), P. A. Evans (U Leicester), N. Gehrels (NASA/GSFC), S. T. Holland (CRESST/USRA/GSFC), E. A.

Sakamoto (NASA/UMBC), E. Troja (INAF-IASFPA), T. N. Ukwatta (GSFC/GWU), L. Vetere (PSU) and H. Ziaeepour (UCL-MSSL) report on behalf of the Swift Team:
At 18:40:39 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 090113 (trigger=339852). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 32.073, +33.456 which is
```
   RA(J2000)  =  02h 08m 18s
   Dec(J2000) = +33d 27' 23"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows about 4 peaks with a duration of about 20 sec. The peak count rate was ~5000 counts/sec (15-350 keV), at ~2 sec after the trigger.
The XRT began observing the field at 18:41:50.1 UT, 70.9 seconds after the BAT trigger. The onboard source-detection algorithm originally centroided on a hot column. No other source was visible in the initial TDRSS sub-image. We are waiting for the full Malindi dataset to detect and localise the afterglow.
UVOT took a finding chart exposure of 150 seconds with the White filter starting 79 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The sub-image covers 25% of the BAT error circle. The overlap of the 8'x8' region for the list of sources generated on-board is 100% of the BAT error circle. This source list is usually complete to about 18th magnitude. No correction has been made for the expected extinction corresponding to E(B-V) of 0.08.
This burst was also detected by Fermi-GBM.
This burst is not to be confused with the BAT trigger (339853) about 12 minutes later on the 1A 1118-61 HMXB source.
Burst Advocate for this burst is H. A. Krimm (krimm AT milkyway.gsfc.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 #8806
J. A. Kennea (PSU) and H. A. Krimm (CRESST/GSFC/USRA) report on behalf of the Swift Team:
Analysis of preliminary data from the BAT trigger 339852 (GRB090213) reveals an uncatalogued point source at RA, Dec = 32.05816, 33.42945 which is equivalent to:
```
RA(J2000) = 02h 08m 13.9s,     
Dec(J2000) = +33d 25m 46.0s
```
with an estimated uncertainty of 8 arcseconds radius (90% confidence). Analysis is ongoing and an improved analysis will be reported as soon as possible.

H. Swan (U Mich), E.S. Rykoff (UCSB), T. Guver (U Arizona), T.A. McKay (U Mich), F. Yuan (U Mich), B. E. Schaefer (Louisiana State), R. Quimby (Caltech), report on behalf of the ROTSE collaboration:
ROTSE-IIId, located at the Turkish National Observatory at Bakirlitepe, Turkey, responded to GRB 090113 (Swift trigger 339852; H. A. Krimm, GCN 8804), producing images beginning 6.4 s after the GCN notice time. An automated response took the first image at 18:49:02.4 UT, 503.2 s after the burst, under windy conditions. We took 10 5-sec, 10 20-sec and 30 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, for both single images and coadding into sets of 10; the field is not crowded. Individual images have limiting magnitudes ranging from 14.9-16.4; we set the following specific limits.

Using the data set from T-120 to T+302 sec from recent telemetry downlinks, we report further analysis of BAT GRB 090113 (trigger #339852) (Krimm, et al., GCN Circ. 8804). The BAT ground-calculated position is RA, Dec = 32.067, 33.436 deg, which is
```
   RA(J2000)  =  02h 08m 16.0s 
   Dec(J2000) = +33d 26' 08.4" 
```
with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 80%.
The mask-weighted light curve shows multiple peaks starting at ~T-10 sec and ending at ~T+30 sec. T90 (15-350 keV) is 9.1 +- 0.9 sec (estimated error including systematics).
The time-averaged spectrum from T-0.9 to T+10.0 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.60 +- 0.10. The fluence in the 15-150 keV band is 7.6 +- 0.4 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T+1.46 sec in the 15-150 keV band is 2.5 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

M.R. Goad, J.P. Osborne, A.P. Beardmore and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team.
Using 752 s of XRT Photon Counting mode data and 3 UVOT images for GRB 090113, 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 = 32.05678, +33.42857 which is equivalent to:
```
RA (J2000): 02h 08m 13.63s
Dec (J2000): +33d 25' 42.9"
```
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 http://www.swift.ac.uk/xrt_positions/Goad.pdf), the current algorithm is an extension of this method.

We have observed the field of GRB 090113 (Krimm et al., GCN 8804) with the 2.5m NOT telescope at Roque de los Muchachos Observatory (La Palma, Spain). Preliminary analysis of a 300s R-band exposure with mid time 20:45 UT (2.08h after the burst) does not show any new source within the enhanced XRT error box (Goad et al., GCN 8809) down to a 3-sigma limiting magnitude of R > 23.4.
GCN Circular #8811
P.A. Evans (U. Leicester) and H. A. Krimm (CRESST/GSFC/USRA) report on behalf of the Swift-XRT team:
We have analysed 5.5 ks of XRT data for GRB 090113 (Krimm et al. GCN Circ. 8804), beginning 93 s after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Goad et al. (GCN. Circ 8809).
The light curve can be modelled with a power-law decay with a decay index of alpha=0.991 (+/-0.042).
A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.28 (+0.20, -0.19). The best-fitting absorption column is 3.20 (+0.63, -0.58) x 10^21, in excess of the Galactic value of 6.7 x 10^20 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 4.0 x 10^-11 (7.8 x 10^-11) erg cm^-2 count^-1.
If the light curve continues to decay with a power-law decay index of 0.991, the count rate at T+24 hours will be 0.0063 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 2.5 x 10^-13 (4.9 x 10^-13) erg cm^-2 s^-1.

F. Olivares (MPE Garching), Andrea Rossi (Tautenburg Obs.), J. Greiner, A. Yoldas (both MPE Garching), and A. Kupcu Yoldas (ESO) report on behalf of the GROND team:
We observed the field of GRB 090113 (Swift trigger #339852; Krimm et al., GCN #8804) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2m MPI/ESO telescope at La Silla Observatory (Chile).
Observations started at 00:35 UT on January 14th, 2009, about 6.1 hrs after the GRB trigger, and continued until the GRB location approached the 20 degree above horizon limit of the telescope, with 8.1 min of total exposures in g'r'i'z' and 12.0 min in JHK. They were performed at an average seeing of 1.8" and at an average airmass of 2.6.
We do not detect any object within the 1.7'' Enhanced Swift-XRT error circle reported by Goad et al. (GCN #8809). Co-added images yield the following upper limits (all in AB system):
```
g' >  23.3 mag,
r' >  23.4 mag,
i' >  22.6 mag,
z' >  22.6 mag,
J  >  21.3 mag,
H  >  20.7 mag and
K  >  20.0 mag.
```
These upper limits are derived based on calibrating the images against the GROND zeropoints as well as 2MASS field stars.

S. R. Oates (MSSL-UCL) and H.A. Krimm (CRESST/GSFC/USRA) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 090113 79s after the BAT trigger (Krimm et al., GCN 8804). We do not detect any source at the enhanced Swift XRT position (Evans et al. GCN 8809). Due to trigger 339853 the automatic target sequence was cut short and only the white and u finding charts were taken. In the u finding chart and in the second orbit of data the XRT position lies outside of the UVOT images. Therefore, we can only report the 3- sigma upper limit for the white finding chart exposure.
The 3-sigma upper limits for the finding chart exposure is:
```
Filter   T_start   T_stop   Exp(s)  Mag (3-sigma upper limit)
-------------------------------------------------------------
white      79       229      147     > 20.73
-------------------------------------------------------------
```
The quoted upper limits have not been corrected for the expected Galactic extinction along the line of sight of E_(B-V) = 0.08 mag. All photometry is on the UVOT photometric system described in Poole et al. (2008, MNRAS, 383, 627).

The MAGIC Imaging Atmospheric Cherenkov Telescope performed a follow-up observation of the BAT burst GRB090113 (GCN circular 8804, Krimm et al.). We received the GCN alert at 18:41:01 UT (T0+20s), before the sunset. Data taking with MAGIC started at 20:06:08 UT (T0+4603s), when the GRB zenith angle reached 5 degrees. The observation continued for 9405 s.
No evidence for VHE gamma-ray emission above the analysis threshold of 94 GeV was found. The observation was carried out in (less sensitive) moon-observation mode from 21:39:01 UT on.
A preliminary analysis, for the hypothesis of steady emission and assumption of a differential photon spectral index of -2.5, yields the following 95% CL differential flux upper limits, including a 30% systematic uncertainty on the telescope efficiency.
```
E (  80- 125 GeV): 0.54 * 10^-10 erg cm^-2 s^-1
E ( 125- 175 GeV): 0.99 * 10^-10 erg cm^-2 s^-1
E ( 175- 300 GeV): 0.10 * 10^-10 erg cm^-2 s^-1
E ( 300-1000 GeV): 0.08 * 10^-10 erg cm^-2 s^-1
for a time window from 20:06:01 UT to 21:37:01 UT

E ( 125- 175 GeV): 0.93 * 10^-10 erg cm^-2 s^-1
E ( 175- 300 GeV): 0.23 * 10^-10 erg cm^-2 s^-1
E ( 300-1000 GeV): 0.08 * 10^-10 erg cm^-2 s^-1
for a time window from 21:39:01 UT to 22:32:01 UT
```
We can also exclude emission of a constant flux in any 100s time bin smaller than:
```
E (  80- 125 GeV): 13.89 * 10^-10 erg cm^-2 s^-1
E ( 125- 175 GeV): 8.88 * 10^-10 erg cm^-2 s^-1
