Marshall (NASA/GSFC), A. Melandri (INAF-OAB), K. L. Page (U Leicester), D. M. Palmer (LANL), M. H. Siegel (PSU) and R. L. C. Starling (U Leicester) report on behalf of the Swift Team:
At 15:12:09 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 131202A (trigger=579982). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 344.056, -21.658 which is
```
   RA(J2000) = 22h 56m 13s
   Dec(J2000) = -21d 39' 27"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single-peaked structure with a duration of about 30 sec. The peak count rate was ~1200 counts/sec (15-350 keV), at ~2 sec after the trigger.
The XRT began observing the field at 15:14:02.9 UT, 113.7 seconds after the BAT trigger. Using promptly downlinked data we find a fading, uncatalogued X-ray source with an enhanced position: RA, Dec 344.0540, -21.6627 which is equivalent to:
```
   RA(J2000)  = 22h 56m 12.96s
   Dec(J2000) = -21d 39' 45.6"
```
with an uncertainty of 2.3 arcseconds (radius, 90% containment). This location is 18 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 (2.29 x 10^20 cm^-2, Kalberla et al. 2005), with an excess column of 4.3 (+3.70/-2.92) x 10^21 cm^-2 (90% confidence).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 116 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 0.03.
Burst Advocate for this burst is D. Kocevski (daniel.kocevski 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 #15561
G. Stratta (OAR/INAF), B. Gendre (ARTEMIS), S. Dall'Osso (IAAT), Giovanni De Cesare (IAPS) report :
We have activated a ToO observation of GRB 131202A with XMM-Newton, starting at 2013-12-03 00:23:14 UTC for about 8 hours and 20 minutes. All ground based follow-up (especially in optical and radio) are encouraged.
This message can be cited.
GCN Circular #15562
A. Nicuesa Guelbenzu, S. Klose, B. Stecklum, and S. Schmidl (TLS Tautenburg) report:
We observed the field of GRB 131202A (Kocevski et al., GCN 15559) with the Tautenburg 1.34-m Schmidt telescope under very high airmass (> 3). Observations in R, I and GunnZ started at 16:23 UT, around 70 min after the GRB trigger.
Inside the 2.3 arcsec XRT error circle (Kocevski et al.) we do not find any new object in any band. We estimate a preliminary magnitude of R > 20.
GCN Circular #15563
U.Quadri, L.Strabla and R.Girelli report:
We imaged the field of GRB 131202A with the robotic telescope of (IAU station 565) Bassano Bresciano Observatory, Italy (member of ISSP: Italian Supernovae Search Project).
The observations started 88m. after the GRB trigger,at the end of the twilight, with our schmidt telescope D=320/400 mm F/D=3.1.
Weather conditions were good.
We co-added 3 series of 20 unfiltered exposures of 120 sec each.
We did not found any optical counterpart in the error box of the XRTcandidate (D. Kocevski et al, GCN 15559).

J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
Using 1178 s of XRT Photon Counting mode data and 2 UVOT images for GRB 131202A, 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 = 344.05424, -21.66247 which is equivalent to:
```
RA (J2000): 22h 56m 13.02s
Dec (J2000): -21d 39' 44.9"
```
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).

Andrew C. Collazzi (NASA/ORAU) reports on behalf of the Fermi GBM Team:
"At 15:12:10.85 UT on 2 December 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 131202A (trigger 407689933 / 131202633), which was also detected by the Swift/BAT and Swift/XRT (Kocevski et al., GCN 15559). The GBM on-ground location is consistent with the Swift/XRT position.
The angle from the Fermi LAT boresight is 86 degrees.
The GBM light curve consists of a single pulse with a duration (T90) of 26 s (50-300 keV). We find the 1.024-s peak flux (10 - 1000 keV), measured starting from T0-2.560, to be 1.5 +/- 0.2 ph/(s cm^2). The time-averaged spectrum from T0-8.2 s to T0+11.3 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.10 +/- 0.25 and the cutoff energy, parameterized as Epeak, is 288.4 +/- 172.0 keV.
The event fluence (10-1000 keV) in this time interval is (1.6 +/- 0.4)E-06 erg/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

We observed the field of GRB 131202A (Kocevski, et al., GCN 15559) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astron=C3=B3mico Nacional on Sierra San Pedro M=C3=A1rtir from 2013/12 3.08 to 2013/12 3.15 UTC (10.81 to 12.32 hours after the BAT trigger), obtaining a total of 1.04 hours exposure in the r and i bands and 0.44 hours exposure in the Z, Y, J, and H bands.
For a source within the Swift-XRT error circle, in comparison with 2MASS, we obtain the following upper limits (3-sigma):
```
   r	> 22.99
   i	> 22.56
   Z	> 21.50
   Y	> 20.68
   J	> 20.43
   H	> 20.05

B.P. Gompertz (U. Leicester), B. Sbarufatti (INAF-OAB/PSU), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC), J.A. Kennea (PSU), V. Mangano (PSU), M.C. Stroh (PSU), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester) and D. Kocevski report on behalf of the Swift-XRT team:
We have analysed 7.1 ks of XRT data for GRB 131202A (Kocevski et al. GCN Circ. 15559), from 99 s to 33.8 ks after the BAT trigger. The data comprise 267 s in Windowed Timing (WT) mode (the first 8 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Osborne et al. (GCN. Circ 15564).
The light curve can be modelled with a power-law decay with a decay index of alpha=2.00 (+0.23, -0.24).
A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.1 (+0.4, -0.3). The best-fitting absorption column is 1.3 (+1.0, -0.8) x 10^21 cm^-2, in excess of the Galactic value of 2.3 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 3.5 x 10^-11 (4.9 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     1.3 (+1.0, -0.8) x 10^21 cm^-2
Galactic foreground: 2.3 x 10^20 cm^-2
Excess significance: 2.2 sigma
Photon index:	     2.1 (+0.4, -0.3)
```
If the light curve continues to decay with a power-law decay index of 2.00, the count rate at T+24 hours will be 6.2 x 10^-6 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 2.2 x 10^-16 (3.0 x 10^-16) erg cm^-2 s^-1.

S. R. Oates (UCL-MSSL) and D. Kocevski (NASA/GSFC/ORAU) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 131202A 117 s after the BAT trigger (Kocevski et al., GCN Circ. 15559). No optical afterglow consistent with the XRT position (Osborne et al., GCN Circ. 15564) is detected in the initial UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the initial exposures are:

Using the data set from T-61 to T+242 sec from the recent telemetry downlink, we report further analysis of BAT GRB 131202A (trigger #579982) (Kocevski, et al., GCN Circ. 15559). The BAT ground-calculated position is RA, Dec = 344.005, -21.650 deg which is
```
    RA(J2000)  =  22h 56m 01.3s
    Dec(J2000) = -21d 38' 58.9"
```
with an uncertainty of 2.6 arcmin, (radius, sys+stat, 90% containment). The partial coding was 63%. The mask-weighted light curve shows a pair of overlapping peaks covering the period from T-10 to T+40 seconds. T90 (15-350 keV) is 30.4 +- 10.9 sec (estimated error including systematics).
The time-averaged spectrum from T-1.62 to T+37.98 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.58 +- 0.26. The fluence in the 15-150 keV band is 6.1 +- 1.0 x 10^-7erg/cm2. The 1-sec peak photon flux measured from T+1.64 sec in the 15-150 keV band is 0.7 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

R. Ruffini, C.L. Bianco, M. Enderli, M. Kovacevic, M. Muccino, A.V. Penacchioni, G.B. Pisani, J.A. Rueda, Y. Wang report:
The X-ray observations of GRB 131202A (1) point to the possibility that it fulfills the IGC paradigm (2,3). A preliminary overlapping of its X-ray (0.3-10 keV in rest-frame) luminosity within the one of GRB 090618, namely an IGC prototype (4), gives an estimate of the redshift of z~10 (see Fig. 1 http://www.icranet.org/images/GCN/GRB131202A_Fig1.pdf). Continuous = monitoring and complementary observations in all possible wavelengths are encouraged.
The extension of the validity of the IGC paradigm to very large cosmological distances has already been clearly demonstrated by the case of GRB 090423 (5) at z=3D8.2 (6,7,8,9,10,11): its X-ray (0.3-10 keV in rest-frame) luminosity again overlaps perfectly well with the one of GRB 090618 (see Fig. 2 http://www.icranet.org/images/GCN/GRB131202A_Fig2.pdf).

GCN Circular #15586
K. Varela, J. Graham, J. Greiner and D.A. Kann (all MPE Garching) report on behalf of the GROND team:
We observed the field of the GRB 131202A (Kocevski et al., GCN #15559) simultaneously in g'r'i'z'JHKs with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at La Silla Observatory (Chile).
Observations started at 01:01 UT on 03 December 2013, 9.5 hours after the GRB. They were performed at an average seeing of 1.4" and at an average airmass of 1.5.
Based on an observation with a total integration time of 6920 s in g'r'i'z' and 5760s in JHK, we detect a source inside the enhanced XRT circle (Osborne et al., GCN #15564) in the i' and z' bands, with magnitudes
```
i' = 24.5 +/- 0.3 mag,
z' = 23.6 +/- 0.2 mag,
```
and 3 sigma limiting magnitudes (all in the AB system) :
```
g'> 25.5 mag,
r'> 25.3 mag,
J > 22.0 mag,
H > 21.4 mag,
K > 19.9 mag.
```
Magnitudes are calibrated against GROND zeropoints (griz) and 2MASS stars (JHK), and are not corrected for the Galactic foreground extinction corresponding to a reddening of E_(B-V) = 0.03 mag in the direction of the burst (Schlegel et al. 1998).
Performing a joint fit with contemporary Swift X-ray data, we find that the detections and upper limits can be explained with a low redshift and high extinction (up to Av ~ 4.2 for z = 0 and SMC dust), with low extinction and a redshift z ~ 5, or combinations in between. The near-negligible NH column density at z = 0 ((1.3+1.0-0.8) x 10^21 cm^-2, Gompertz et al., GCN #15567) and assuming a non-extreme dust-to-gas ratio point to a higher probability for the z ~ 5 scenario.
We note that in any case, the significant detection in i' and the i'- z' color conservatively imply z < 6, in contrast to the prediction by Ruffini et al. (GCN #15576).
