In [vsnet-campaign-sn 401] (Apr. 8):

># The host galaxy of SN 2002by is ESO 139-G34, in which the expected
># maximum for typical SN Ia is mag about 15.5.  According to IAUC
># 7866, the CTIO spectrum (only blueward) shows that the new object is
># indeed a supernova, possibly of type I.  The position of SN 2002by
># is: R.A. = 17h50m18s.58, Decl. = -59o33'51".6 (2000.0), which is
># about 25" west and 13" south of the center of ESO 139-G34.  

According to IAUC 7910, the spectrum of SN 2002by was taken at Siding
Spring Observatory on May 18.53UT, which recealed that it is of type
Ia, about 2 months after maximum.  Thus, the discovery, which made on
Mar. 31 UT, was at around maximum phase.
