D. A. Perley (LJMU) and Anna Ho (Caltech) report:
We observed the location of ZTF20abbiixp/AT2020krl (Ho et al., GCN
27799), the presumed optical afterglow of GRB 200524A (Fana Dirirsa et
al., GCN 27797), with the 2m robotic Liverpool Telescope between UT
2020-05-24 21:39 and 21:53. We acquired 120s of exposure time in each
of the u, g, r, i, and z filters. Photometry is as follows (all times
relative to the LAT trigger as reported in GCN 27797):
t_mid(d) filter magnitude
-------- ------ ----------
0.6921 z 20.49 +/- 0.15
0.6941 i 20.86 +/- 0.09
0.6961 r 21.03 +/- 0.07
0.6981 g 21.32 +/- 0.06
0.7000 u 21.64 +/- 0.24
