This page is devoted to information on Supernova 1998es in NGC 632 Basic information on this SN, including the last reported brightness, on this Supernova can be found on the main supernova page. Information on the original web pages for many of these images can be found on the Supernova links web page.
NOTE: There is a mag 15 star located 10" northeast of NGC 632. After a long drought of very little Sn activity we finally get one which is bright enough to be findable by "amateur" telescopes again.

Light Curves and Spectra:
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.
