Sziasztok Csilla-sok!
Uj szupernovat fedeztek fel az NGC2595-ben, felfedezeskor 15,5 mg volt.
A viszonylag kozeli felfedezesi datum miatt talan meg elcsipheto.

SUPERNOVA 1999aa IN NGC 2595
Ron Arbour, South Wonston, Hants, U.K., reports his discovery
of an apparent supernova (mag about 15.5) in the galaxy NGC 2595 on
an unfiltered CCD image (limiting mag about 17.5) taken on Feb.
11.0166 UT using a 0.3-m f/6.3 reflector in the course of his
supernova patrol. M. Armstrong confirmed the new object's
existence via two exposures (the first at Feb. 11.0461 UT),
measuring its position as R.A. = 8h27m42s.03, Decl. = +21o29'14".8
(equinox 2000.0), which Arbour notes to be 1" east and 28" north of
the center of NGC 2595. Nothing is present at this position on six
images taken by Arbour in 1998 Feb. and Mar. (limiting mag about
17.5), nor is it present in the Digitized Sky Survey. Arbour notes
that a CCD image obtained by M. Schwartz with the Tenagra 0.35-m
patrol telescope on Feb. 12.07 yields an offset of 2" east, 27"
north, while an image by Schwartz obtained on 1998 Nov. 26.45 shows
no object at this location.
