E. Semkov (Institute of Astronomy, Sofia, Bulgaria) report:
The afterglow of the HETE burst (H2652) GRB 030329 (Peterson & Price,
GCN 1985; Torii: GCN 1986) was observed with the 50/70 cm Schmidt
telescope of the National Observatory Rozhen (Bulgaria) on 2, 3 and 3
April, Rc filter, 5 x 300 sec coo-added exposures.
The observations were carried out under good seeing conditions. Using
field photometry of Henden (GCN2082) we estimate the brightness of the
optical afterglow in Rc band as follows.
2.04 (UT 21.3) R=17.66 +/-0.09
3.04 (UT 20.2) R=17.73 +/-0.11
4.04 (UT 19.5) R=18.11 +/-0.18
