H. Kirbiyik (TUG) report on behalf of a larger collaboration
We observed the field of Swift GRB 130831A (Hagen et al. GCN#15139)
with the 1.0 meter T100 telescope (TUBITAK National Observatory,
Antalya - Turkey), starting August, 31; 18:27:23 UT (~ 5.4 hours after
the trigger). Observations were carried out in the R filter under moderate
weather conditions. We detected a new source in 300 s R band
image at a position that is consistent with Swift/UVOT (Hagen et al.
GCN#15139)
Using USNO-B1 star USNO-B1 1193-0589854 (RA= 23:54:29.226, Dec=
+29:23:08.41) in the field, the magnitude of the OT were estimated as;
t-t0 (hr) exp.(s) filt mag err (+/-)
5.38 300 R 17.98 0.034
5.48 300 R 17.99 0.035
Further observations using the same filter are ongoing.
We are grateful to the TUBITAK National Observatory staff for promptly
scheduling the observations and their technical support.
