Several 300 sec. exposures in  R (Johnson)  obtained\nduring Apr. 4.  Based on filed photometry by A. Henden (GCN 2023)  we\nestimate the OT magnitude:\n\nMid time                      exposure       R\n(UT)\n\n Apr 4.7686                  4x300c        18.12 +/-0.11\n       4.8236                  5x300�        18.32 +/-0.10\n       4.8412                  5x300c        18.04 +/-0.07\n\nAfter nearly flat period between end of 030402 and end of 030403 (GCN\n2083,2084,2092) the OT definitely start  a new fading phase. A power-law\nindex between Apr 3.8160 and  Apr 4.8049  can be estimated as alpha ~1.7\n\nA 10x180 sec. exposure image obtained on April 04.8012 can be found in\nhttp://grb.rssi.ru/GRB030329/030329_030404_at64.gif\n\nThis message may be cited.",
