SUBJECT: GRB080210: optical observations

E. Klunko (ISTP), A. Pozanenko (IKI) on behalf of larger GRB follow up 
collaboration  report:

We observed afterglow (Klotz et al. GCN 7280) of GRB080210  (Grupe et al. 
GCN 7281)  with 1.5m telescope of Sayan observatory (Mondy) on Feb.10 
between (UT) 21:36:37 - 22:49:36. The afterglow is marginally detected 
(SNR=1.8) in coordinates R.A.(J2000) = 16 45 03.98 Dec.(J2000) = +13 49 
35.8. A photometry against USNO-B1.0 is following:

T0+       Exposure  R_mag
(mid)

0.594 d  47x60 s   21.8

The afterglow at 0.594d appears ~1 magnitude brighter than expected from  a 
slow decay rate of alpha ~0.85 (Perley et al. GCN 7298).
