SUPERNOVA 2008ea IN NGC 7624
A. Dimai, Cortina d’Ampezzo, Italy, on behalf of the
CROSS program (cf. IAUC 7373), reports the discovery of an
apparent supernova (mag about 17.0) by F. Martinelli and M.
Biagietti, Santa Maria a Monte, Pisa, Italy; and G. Iafrate,
Cortina, Italy, on two unfiltered CCD images (limiting mag
about 18.5) taken on July 6.07 UT with the 35.6-cm
Schmidt-Cassegrain telescope of the Tavolaia Observatory
(Santa Maria a Monte, Pisa). The new object is located at
R.A. = 23h20m22s.58, Decl. = +27o19′10″.2 (equinox 2000.0),
which is 2″ west and 15″ north of the nucleus of the galaxy
NGC 7624, superimposed on a faint H II region that is
visible on two red Palomar Sky Survey (POSS) plates. CROSS
images of the same field taken on Jan. 21 showed nothing at
the position of 2008ea (limiting mag about 18.0), and 2008ea
does not appear on POSS infrared, red, and blue plates. The
discovery image of 2008ea is posted at URL
http://www.cortinastelle.it/cross/NGC7624-20080706.jpg.
Further to CBET 1426, R. Mostardi, W. Li, and A. V.
Filippenko, University of California, report the independent
LOSS discovery of 2008ea at mag 17.5 on an unfiltered KAIT
image taken on July 7.45, the position end figures given as
22s.62, 11″.0 (offset 0″.9 west, 15″.6 north of the galaxy
center). Nothing is visible at this position on a KAIT
image taken on June 21.44 (limiting mag 19.0).
