(IAAC) Fwd: Possibly BRIGHT SN2000db in UMa galaxy NGC 3949
I do not post requests for confirmation of SNe outside the SN email lists. This
is now an announced discovery however (albeit with some uncertainties), and is
certainly worth checking out if your evening twilight ends early enough (or if
this area of UMa is sufficiently high after twilight) for you to catch this
faint glimmer a mere 45o from the Sun! At any rate, the host galaxy is only a
degree or so West of chi UMa, so should not be a difficult find...
Clear skies,
Lew Gramer

Subject: [vsnet-campaign-sn 41] SN 2000db in NGC 3949
Dear SN watchers,
IAUC 7475 tells that M. Aoki has discovered a quite bright SN. The
host galaxy is a member of UMa cluster of galaxies, which is as near
as the Virgo cluster. Further observation and the classifications are
urgently needed.
The discovery was made on Aug. 6.498 UT when the SN was mag 14.3.
The reported location is: R.A. = 11h53m39s.75, Decl. = +47o51'46".6
(equinox 2000), which is about 20" northwest of the center of the
tilted open-spiral (SA(s)bc) galaxy NGC 3949. Compareing with DSS
image, it is overimposed on the bulge region and some field stars (or
condensations of the host) can be found in this direction. The
identification should be done carefully.
The expected maximum of SN Ia on this distance is about mag 12. If
it is truely of type Ia, it should be observed much brighter than 14
mag on this night. The follow-up observation is surely encouraged.
Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
