GCN42343) issued at 03:12:02 UT.\n\nFRAM obtained its first unfiltered exposure 42 seconds\nafter the trigger, at 03:12:44 UT, followed by a\nsequence of 20s and 60s exposures.\n\nAn optical transient is detected at the UVOT position.\nIt appears at R(Vega) roughly 15.5 mag at T0 + 78s and\nfades to roughly 18.0 mag by the end of our 28 minutes\nobserving run consistent with detections by Lipunov et.\nal. GCN42346, Hu et. al. GCN42363 and Kuin et. al.\nGCN42353.\n\n",
