and S. Cikota (CAHA) report:
We observed the afterglow of GR230328B (Fermi/GBM Detection: Fermi GBM
Team GCN 33526, Swift detection: Gropp et al. GCN 33527) with CAFOS
mounted on the 2.2 m telescope at the Calar Alto Observatory (Almeria,
Spain).
The observations consisted of 5 x 360 s in Rc-band and were obtained at
mean
epoch of 0.4717 days after the GRB. The afterglow is clearly detected with
Rc = 21.00 �� 0.06 (AB) mag measured against comparison stars from the
PanSTARRS catalogue.
