... e prima assoluta per Giulia, Fabio e Mauro, complimenti!
Presentiamo in anteprima la nuova nata e la circolare di conferma:

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).
