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