Dear ASCA users, As you may know, a gamma-ray burst was observed with CGRO/BASTE from the gamma-ray burst repeter SGR1806-20 (IAU Circ. No. 6242), suggesting its turn-on to a high active state. We install a TOO observation of 40-ksec exposue in the span of October 16, by replacing with the target NGC 1672 (JPN PriorityB,PI; H. Awaki). NGC 1672 is a target that is visible all the season and will be be rescheduled in early December. F.
