There is a # very bright (mag about 11) foreground star about 20" due east of the # nucleus of UGC 5234. The CfA team took a spectrum on Jan. 29.34, # which revealed that it is type Ia supernova well (about 12 days) # before maximum. The expected maximum for typical SN Ia is mag about # 16.3, if an extinction within the host galaxy is small.
