Johan P. U. Fynbo (DAWN/NBI), Daniele B. Malesani (DTU Space), Abel de
Burgos Sierra (NOT), Thomas Augusteijn (NOT), report on behalf of a
larger collaboration:
On 2020 March 24.97 UT (6 hr 39 min after the trigger) we observed the
field of GRB 200324A (Dichiara et al., GCN 27428; Beardmore et al., GCN
27430) with the Nordic Optical Telescope equipped with ALFOSC in the
SDSS r filter, for a total integration time of 300 s. We find no
evidence for afterglow emission above a 3-sigma limit of about 23 mag.
Our result is consistent with the non-detection by Stecklum et al. (GCN
27431).
