GCN Circular 2190
V.Rumyantsev (CrAO), A.Pozanenko (IKI) report: We have imaged the error box of the HETE GRB030429 (HETE trigger 2695) with AT-64 telescope of CrAO. Several unfiltered images with exposures of 120 s were obtained in Apr. 29 between (UT) 18:19 and 20:57. The OT found by A.Gilmore at al. (GCN 2184) is marginally visible in co-added image. The midtime of the co-added image (39x120 s) is Apr. 29.820. Due to short focal length of AT-64 (F=900mm, F/1.4) the OT appears to be in the wing of the star USNO A2.0 675-11945727 RA =12 13 07.92 DEC=-20 54 45.3 R=17.90 B=20.50 Star 1 in the image at http://grb.rssi.ru/GRB030429/030429_030429_at64.gif The limiting magnitude of the image calibrated with USNO A2.0 catalog R-band is 20.7, so we can estimate the OT magnitude as brighter as R=20.7m. Our estimation is consistent with OT decay slope 2 which implies the observation by A.Gilmore at al. (GCN 2184). Detailed calibration and PSF analysis is in a progress.
