[vsnet-alert 5411] SNe 2000el, 2000er, 2000ev, & 2000ex

Dear SN watchers,

  There are many important informations about SNe in these three days.
I would like to summerize them in this article.  I will write other
articles about the very bright SN 2000ew and 2000ey. 

  SN 2000el [vsnet-alert 5387, Nov. 25] was independently discovered
by KAIT team, and it is revealed that this SN was first detected on
Oct. 23.1 and is of normal type II.  The photometry is quite difficult
because it is very close to the nucleus of the host galaxy.

  SN 2000er [vsnet-alert 5389, Nov. 27] is observed as mag 15.4CR on
Nov. 28.  Because of the spectral peculiarity and the scarcity of type
Ib, it is very important target for the follow-up photometry.  

  SN 2000ev was discovered by F. Manzini on Nov. 27.10 at mag 16.5
(IAUC 7529).  The reported position is only the offsets: 4".5 west and
19" north of the nucleus of the tilted spiral(?) galaxy UGC 3500. The
rough estimate of the coordinates of UGC 3500 is R.A. = 6h47m55s,
Decl. = 84o09'43" (2000.0), and those of SN 2000ev are end figures
52s, 10'02".  The more precise astrometry is needed.  The spectroscopy
shows that it seems to be of young type IIn.  The expected maximum of
normal SN Ia is about mag 15.5.

  SN 2000ex was discovered by KAIT team (IAUC 7530).  It has been mag
17.6-17.8 between Nov. 17.4 - 27.3, and was revealed as of type II. 

Sincerely Yours,
