GRB 240814A was also observed by Fermi/GBM (GCN 37176). The GRM light curve shows that this burst consists of a single pulse with a duration of about 13 s.

GRM is developed by the Institute of High Energy Physics (IHEP) of CAS. The SVOM point of contact for this burst is: Li Zhang (IHEP)(zhangli@ihep.ac.cn).
