Dear SN watchers,

  A bright supernova has been discovered after about 1 month absence. 
IAUC 7050 tells that KAIT team has discovered SN 1998es, which
position is R.A. = 1h37m17s.50, Decl. = +5o52'50".3 (2000.0), which 
is about 11" north of the nucleus of NGC 632.  M. Aoki, R. and Y.
Kushida have confirmed it.  

  Estimated from its recession velocity, NGC 632 is a some near-by
galaxy which is about 3 times further than Virgo.  The expected
maximum magnitude of typical SNeIa on this distance would be about
14.5 mag.  Its morphorogy type is uncertain, but some catalogs take it
as face-on S0 galaxy.  There is a foreground star (about 15 mag) at
about 10" east and 17" north from the core of NGC 632. 

  The reported magnitudes (vsnet-obs 18034) tells that SN 1998es is
around 14.5 mag now.  Further magnitude estimates and spectroscopic
confirmations are encouraged. 

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
