cf. vsnet-chat 1170 http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-chat/msg01170.html Dear SN watchers, >As Dr. Kato noted on [vsnet-chat 1169], typical SNeIa on this distance >will reach 15.3 mag or so at their maximum. IAUC 6997 tells that SN 1998dk is a type Ia supernova close to maximum light (Aug. 24 spectrum). Further photometry is encouraged, because the reported magnitude (see above link) is very dimmer than expected. Sincerely Yours, Hitoshi Yamaoka, Kyushu Univ., Japan yamaoka@rc.kyushu-u.ac.jp
