GRB 200524A: OAJ multicolor afterglow detection

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.
