on behalf of the GRB OT observing program at the Konkoly Observatory.
On 09 september 2010 02:25:57 UT (45390 s after the burst) we observed the
field of GRB 100906A detected by Swift (trigger=433509; Markwardt et al.,
GCN 11227) with a 60/90 cm Schmidt telescope located at the Mountain Station
of the Konkoly Observatory using R filter. The exposure time of the CCD images
were 300 s. We clearly detected the fading afterglow at RA(J2000) = 01h 54m
44.12s Dec(J2000) = +55d 37' 49.3" (astrometry with ASTROMETRICA using UCAC3
catalogue.) with an uncertainty of 0.2 arcseconds.
