MASTER (http://observ.pereplet.ru) responded to GRB 050824 (Swift trigger
151905). The first image was 764 sec after
SWIFT GRB050824 detection under the
not very good weather condition (Moon light).
We see OT J. Gorosabel (GCN 3865) with m = 17.5 (unfiltered close to R,
exp. 45 sec) on 2-3 sigma level. On summ of 9
images from 19.5 up to 28.5 minut after GRB Time (23 12 16.00 UT) m= 18.0 on 5
sigma.
UT After GRB time m
23 25 00 764s 17.9
23 31 44 19.5min - 28.5 min 18.3
23 31 44 19.5min - 37.75 min 18.8
The JPG-image of the summ will be available at
http://observ.pereplet.ru/images/GRB050824/1.jpg .
The reduction is continuing.
