J. Kelemen (kelemen at konkoly.hu) on behalf of the GRB OT observing program
at the Konkoly Observatory.


Starting on the evening 23/03/2015 18:30 UT we observed the field GRB 150323A
(A. Amaral-Rogers et al. GCN 17611, and M.R. Goad et al. GCN 17615).
We can confirm the presence of the supposed afterglow reported by
S. B. Cenko (NASA/GSFC) and D. A. Perley (Caltech) (GCN 17612) at the position

RA: 08:32:42.69 DEC: 45:27:53.6

Our position and the P60 position are the same within 1 pixel.

On the coadded images (total exposure time = 2400 sec) we measured an R -band 
magnitude of m(R) = 20.3 +/- 0.14 with respect to nearby USNO-B1.0 stars.
