(MAO)  on behalf of larger GRB follow up collaboration  report:

We observed the afterglow of GRB 080810 (Page et al. GCN 8080) with  AZT-22 
(1.5 m) telescope of Maidanak observatory (MAO) in  R band  on Aug. 12 (UT) 
(20:18:17 -  21:07:58) and Aug. 14 (20:26:35  - 21:33:00).   A photometry of 
combined images is based on several SDSS DR6 field stars:

T0+         Filter  Exp.  mag.           UL
mid., days                               (3 sigma)


2.315      R      2700    21.36 +/-0.09  23.10
4.326      R      3600    n/d            22.30

The photometry in R-band is an agreement with power law decay index  (alpha 
= 1.8)  reported by Thoene et al (GCN 8106) for this phase of  the light 
curve.
