B. Stecklum, S. Klose, A. Nicuesa Guelbenzu, S. Melnikov, and F. Ludwig (all 
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.
