SUBJECT: GRB 050129: a weak long GRB detected with INTEGRAL

D. Gotz, S. Mereghetti (IASF, Milano), A. Bodaghee, S. Shaw, M. Beck
(ISDC, Versoix) and J. Borkowski (CAMK, Torun) on behalf of the IBAS
Localization Team report:

A 20 s long GRB has been detected by IBAS in IBIS/ISGRI data at 20:03:03
UT on Jan. 29. Due to its faintness no automatic IBAS Alert has been
delivered. Its coordinates (J2000) are:

RA:  252.7998 [degrees]
DEC:  -3.0788 [degrees]

with an uncertainty of 2.7 arcmin (90% c.l. radius).

Its peak flux (20-200 keV, 1s integration time) is about 0.26 ph (3E-08
erg)/cmsq/s, which classifies it among the faintest INTEGRAL GRBs.
