Description

Observation of SN 19841 in the Sc galaxy ESO 323-G99 are presented. This object was discovered about 15 days before maximum light and was observed photometrically over a period of five weeks. A spectrum obtained near maximum shows that this supernova was a relatively distant Type-Ib event. Like other Type-Ib supernovae, 19841 was characterized by a red (B-V) color and low absolute magnitude at maximum. Comparison with preoutburst photographs shows that this supernova was located in an interarm region, approximately 1 kpc from the nearest bright H II region. It is important to be able to distinguish supernovae of this type from Ia events, considering the interest in using the latter objects as cosmological standard candles. 33 refs
