M. Blazek, D. A. Kann (both HETH/IAA-CSIC), A. de Ugarte Postigo
(HETH/IAA-CSIC, DARK/NBI), C. Thoene, J. F. Agui Fernandez (both
HETH/IAA-CSIC), and N. Maicas (CEFCA) report:
We observed the field of GRB 200524A (Fermi-LAT detection: Dirirsa et
al. GCN #27797, Fermi GBM detection: Pookalil et al., GCN #27809) with
the T80 0.8m telescope at the Observatorio de Javalambre (Teruel,
Spain). Observations consisted of 3 x 300 s in g', 2 x 300 s in r', and
5 x 180 s in i' and z' each.
The afterglow (Ho et al., GCN #27799, Kumar et al., GCN #27800,
Rumyantsev et al., GCN #27802, Sanwal et al., GCN #27803, Perley et al.,
GCN #27805, Kumar et al., GCN #27806, de Ugarte Postigo et al., GCN
#27807) is well-detected in each image. In the stacked r' image centered
at 21:59:24 UT (mid-time 0.705135 days after the Fermi GBM trigger), we
measure r' = 21.08 +/- 0.04 mag (AB mags) against PanSTARRS stars in the
field.
