We observed the field of GRB 081126 (Margutti et al GCN 8554) with the Z-600 telescope of Mt. Terskol observatory. Series of unfiltered exposures were taken between Nov.26 (UT) 21:48:45 - 22:34:35. A photometry of the afterglow (Andreev et al, GCN 8558, Holland et al, GCN 8564) against USNO-B1.0 (R2) field stars is following ...Full Text

"At 21:34:09.06 UT on 26th November 2008, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 081126 (trigger 249428050 / 081126899) which was also detected by the SWIFT-BAT (Margutti et al. 2008, GCN Circular 8554)...Full Text

"We used the Very Large Array to observe the field of view toward optically bright GRB 081126 (GCN 8554) at a frequency of 8.46 GHz on 2008 Nov 28.97 UT. The GRB radio afterglow is undetected and the peak radio flux at the UVOT position (GCN 8564) is 24 ± 64 uJy. ...Full Text

Swift observations of GRB 081127 have been terminated in favor of the more interesting GRB 081126. The observations of GRB 081126 will continue through November 29 and possibly longer. ...Full Text

We confirm variability of the source identified by Sergeev and Pozanenko (GCN 8558). The object was observed from Crni Vrh Observatory with a 60 cm telescope using R filter and a CCD in about 5 arc-second seeing conditions. First 60 s exposure started at 2008-11-26 21:35:32 UT. All twenty exposures were of 60 s. The table contains the time since the Swift GRB detection to the middle of exposure...Full Text

We observed the field of GRB 081126 detected by Swift (trigger #335647) with the 14-inch Goddard Robotic Telescope (GRT) located at the Goddard Geophysical and Astronomical Observatory (http://cddisa.gsfc.nasa.gov/ggao/). ...Full Text

We confirm the optical afterglow of GRB 081126 reported by Sergeev & Pozanenko (2008, GCN 8558). A re-examination of the UVOT data shows that there is a fading source at ...Full Text

The long GRB 081126 (Margutti et al., GCN 8554, Sato et al. GCN 8557) triggered Konus-Wind at T0=77649.857 s UT (21:34:09.857)....Full Text

We have analysed the first 5 orbits of Swift-XRT data obtained for GRB 081126 (Margutti et al., GCN 8554), covering 100 s of Windowed Timing (WT) and 9.1 ks of Photon Counting (PC) mode data, respectively, between 77 and 24 ks after the trigger. The UVOT-enhanced XRT position was given by Osborne et al. in GCN 8556....Full Text

The Swift/UVOT observed the field of GRB 081126 starting 56 s after the BAT trigger (Margutti, et al. 2008, GCN 8554). Settled exposures started at T+75 s. We do not find any new source, relative to the DSS or 2MASS, or any variable source inside the UVOT-enhanced XRT error circle (Osborne, et al. 2008, GCN 8556). Preliminary 3-sigma upper limits for detecting a source in the co-added images...Full Text

We observed the field of GRB 081126 detected by SWIFT (trigger 335647, Margutti et al GCN 8554 ) with the Z-600 telescope of Mt. Terskol observatory. A set of 90 s unfiltered exposures was taken starting (UT) Nov. 26 22:07:20. In a combined image of 3x90 s we detect a new object not presented in DSS2(R), in near vicinity to the object of USNO-A2.0 1350-14391154. A preliminary astrometry...Full Text

Using the data set from T-120 to T+183 sec from the recent telemetry downlink, we report further analysis of BAT GRB 081126 (trigger #335647) (Margutti, et al., GCN 8554). The BAT ground-calculated position is RA, Dec = 323.526, 48.714 deg, which is ...Full Text

Using 2152 s of XRT Photon Counting mode data and 1 UVOT images for GRB 081126, 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 = 323.5147, +48.7098 which is equivalent to: ...Full Text

At 21:34:10 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 081126 (trigger=335647). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 323.542, +48.709 which is ...Full Text Displaying messages 1 to 15
