We observed the field of Swift GRB 100424A (Hoversten et al., GCNC 10667)
with the 0.5m telescope D50 in Ondrejov (Czech Republic), starting at
23:27:02 UT, i.e. 06:54:20 after the trigger. A sequence of 20s unfiltered
images was obtained. We coadded 60x20s exposure, obtaining an image with a
limitting magnitude Rc~19.3, with an effective exposure time 7.35h after
the trigger (23:54UT). We do not detect any new source within the XRT
localization (Evans et al., GCN10699).
