On 08 august 2010 21:29:00 UT (130547 s after the burst) we observed the field
of GRB 100807A detected by Swift (trigger=431128; Grupe et al., GCN 11067)
with a 60/90 cm Schmidt telescope located at the Mountain Station of the
Konkoly Observatory using R filter. The total exposure of the coadded CCD
images were 1800 s. We examined the position reported Cenko et al., GCN 11073.
No fading object brighter than 21.6 +/- 0.2 was detected.
