>Dear SN fans,
>  Another SN was discovered by English amateur astronomer M.
>Armstrong. This SN is very remarkable!
>  According to IAUC 6875, discovery was made on Apr 13.05UT when SN
>was 14.9 mag. The host galaxy is Sbc galaxy NGC 3982. The location of
>the new star is R.A. = 11h56m26s.00, Decl. = +55o07'38".8 (2000.0),
>which is 18" west and 7" north of the center of the host. Type
>definition has not been reported yet.  On Apr. 13.8 exposure, this new
>star was about 14.5 mag, which indicates that this SN should be on the
>brightening phase (very early phase).
>  The distance module of the host galaxy NGC 3982 is m-M = 31.15
>(from Turry's nearby galaxy catalog), which shows that this galaxy is
>on the same distance with Virgo cluster.  NGC 3982 = UGC 6918 = IRAS
>11538+5524 = PGC 37520 is Seyfert 2 galaxy, and also detected by
>ROSAT.  Typical SNeIa on Virgo distance would be about 12 mag or so at
>their maximum (without reddening), and a some (~2mag) dimmer if it is
>of other types.  Following photometries and spectroscopic observations
>are strongly urged.  Especially it can provide the nature of SN on
>very early phase.
