Several 300 sec. exposures in  R (Johnson) spectral band\nwere obtained during Apr. 2. Based on filed photometry by A. Henden (GCN\n2023)  we estimate the OT magnitude:\n\nMid time              exposure     R\n(UT)\n\n2.7648                 5x300c       17.83  +/- 0.08\n2.7929                 5x300c       17.76  +/- 0.08\n2.8436                 5x300c       17.89  +/- 0.07\n2.8739                 5x300c       17.76  +/- 0.09\n\nAfter steep decay between  Apr 1. and  Apr. 2 we observed a flattening of\nlight curve which may be a start of new episode of re-brightening.\n\nThis message may be cited.",
