Soffitta, for the SuperAGILE team, report: The long-duration, very intense GRB 120129A was observed by Konus-Wind, MESSENGER (GRNS), AGILE (MCAL and SuperAGILE), Fermi (GBM), and Swift (BAT) at about 50146 s UT (13:55:46). The burst was outside the coded fields of view of the BAT and SuperAGILE. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 30.440 (02h 01m 46s) +59.282 (+59d 16' 55") Corners: 23.362 (01h 33m 27s) +68.842 (+68d 50' 33") 31.740 (02h 06m 58s) +56.353 (+56d 21' 09") 34.401 (02h 17m 36s) +51.346 (+51d 20' 44") 28.869 (01h 55m 29s) +62.399 (+62d 23' 58") --------------------------------------------- The error box area is 2.7 sq. deg, and its maximum dimension is 18.3 deg. This box can be improved. The time history and spectrum will be given in a forthcoming GCN Circular. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB120129_T50148/IPN/

Circular_text TITLE: GCN CIRCULAR NUMBER: 12905 SUBJECT: Konus-Wind observation of GRB 120129A DATE: 12/01/31 10:18:12 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, E. Mazets, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report: The long intense GRB 120129A (localized by IPN: Golenetskii et al., GCN 12904) triggered Konus-Wind at T0=50148.403s UT (13:55:48.403). The observation is performed against very high and variable background count rate caused by solar charged particles. The burst light curve shows two bright partly overlapped pulses. A total duration of the burst is ~4 s. The emission is seen up to ~5 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB120129_T50148/ As observed by Konus-Wind the burst had a fluence of (2.7 0.7)x10-5 erg/cm2, and a 16-ms peak flux, measured from T0+0.672 s, of (3.3 1.0)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum of the burst (measured from T0 to T0+3.328 s) is best fitted in the 20 keV - 5 MeV range with the GRB (Band) model, for which: the low-energy photon index alpha = -0.76 (-0.09, +0.09), the high energy photon index beta = -2.9 ( <-2.3), the peak energy Ep = 326(-38, +52) keV, chi2 = 66.5/76 dof. The spectrum at the maximum count rate (measured from T0+0.512 to T0+0.768 s) is best fitted is best fitted in the 20 keV - 5 MeV range with the GRB (Band) model, for which: the low-energy photon index alpha = -0.51 (-0.19, +0.21), the high energy photon index beta = -2.3 (-1.4, +0.3), the peak energy Ep = 317(-66, +92) keV, chi2 = 54.2/61 dof. All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.

Dormidontov, V.Sennik Kislovodsk Solar Station of the Pulkovo Observatory MASTER II robotic double telescope (FOW=2x4 square degrees, http://observ.pereplet.ru) located in Tunka was observed the GRB120129A (S. Golenetskii et al., GCN Circ 12904) IPN triangulation error-box using 9 diffent fields. Observations proceeded since 2012-01-30 20:50 to 2012-01-30 22:50 i.e aprox. 1.3 days after grbtime. On our images we haven't found an optical transient within IPN error-box (S. Golenetskii et al., GCN Circ 12904). Unfiltred upper limit is 18.5 on each image. There is a one strange OT MASTER022229.64+523924.9 which seen only at one image.
