of larger GRB IKI FuN collaboration:
We observed the the optical afterglow (e.g. Sonbas al., GCN 24888;
Siegel al., GCN 24889) with CDK700 telescope (NUTTelA-TAO project) of
Assy-Turgen observatory starting on June 28 (UT) 15:30:37 in R-filter.
We clearly detect the optical afterglow (Sonbas al., GCN 24888;
Siegel al., GCN 24889).
Preliminary photometry of the afterglow is following.

The photometry is based on the nearby USNO-B1 (R2) stars.
We encourage spectroscopic observations to determine redshift and
nature of the burst.
