Tautenburg) report:
We observed the field of GRB 200324A (Dichiara et al., GCN 27428) with the
Tautenburg 1.34m Schmidt telescope equipped with the TAUKAM 6k x 6k CCD camera
and the wide V-band filter (VB). The transmission curve of this filter closely
follows the Gaia GBP filter. Observations started at 20:08:15 UT and consisted
of 5x5 min exposures.
Inside the enhanced XRT error circle (Beardmore et al., GCN 27430) we do not
find any optical transient. Based on Gaia DR2 stars in the field, we provide an
upper limit of VB > 22.0 mag (Vega system; 3.5 hr after the burst). We note
that only ~5 arcsec north of the center of the XRT error circle lies the faint
SDSS-DR8 source J145041.56+355635.6, possibly the GRB host galaxy.
