report:
We observed the field of GRB090529A (trigger=353540, Sakamato et al. 2009
GCN Circ. 9430, also GCN Circ. 9431-9436,9448,9449,9457) with the
Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe, TUBITAK National
Observatory, Turkey) on 30 May starting at 00:09:01.86 UT about 9.94 hours
(0.414 d) after the burst
using the TFOSC CCD (burst detected at 14:12:35 UT with Swift Burst Alert
Telescope (BAT)).
We obtained one 900 sec exposure using the R band filter (Bessell filter). We
found the afterglow candidate at the location designated by the Swift XRT
position given by Osborne et al. 2009 GCN Circ. 9433. We performed PSF
photometry using DAOPHOT within MIDAS software on the 13.3 by 13.3 arcmin field
around the afterglow candidate. We calibrated the R band magnitude
using the same USNO-B1 reference star noted by Kann et al. 2009 GCN Circ.
9436. The GRB090529 afterglow candidate is detected at R = 21.2+/-0.2 mag.
