SN 2001ad

IAUC 7596 reported the Beijing discovery of SN 2001ad. From the recession velocity of the host galaxy (3320 km/s from NED), the expected maximum of the typical unreddened SN Ia is around mag 15. The reported magnitudes of SN 2001ad (17.4:C on Mar. 11.8 by Beijing team; 18.4C: on Mar 13.5 by KAIT) suggest, however, that it will not become so bright (vsnet-campaign-sn 165).
