SN2003hu 20030831.0 <195C ARM SN2003hu 20030906.968 180C ARM SN2003hu 20030907.919 180C ARM # SN 2003hu (19:11:31.40, +77:53:35.2 (J2000.0), offset = 4"W, 3"S) is # hosted by an anonymous galaxy with a bright nucleus (possibly # interacting with 16" NW smaller galaxy). It is about 204" west and # 120" south of UGC 11423. If the host galaxy and the new object is # at the same distance as UGC 11423, the expected maximum for typical # SN Ia is mag about 16.9.

The UCB team retook a spectrum of SN 2003he on Sept. 3, and revealed that it is type Ia supernova about a week after maximum. It shows a blue continuum.
