Malesani (DTU Space), Abel de \nBurgos Sierra (NOT), Thomas Augusteijn (NOT), report on behalf of a \nlarger collaboration:\n\nOn 2020 March 24.97 UT (6 hr 39 min after the trigger) we observed the \nfield of GRB 200324A (Dichiara et al., GCN 27428; Beardmore et al., GCN \n27430) with the Nordic Optical Telescope equipped with ALFOSC in the \nSDSS r filter, for a total integration time of 300 s. We find no \nevidence for afterglow emission above a 3-sigma limit of about 23 mag. \nOur result is consistent with the non-detection by Stecklum et al. (GCN \n27431).",
