SUPERNOVA 2009bu IN NGC 7408
     Alessandro Dimai, Cortina d'Ampezzo, Italy, on behalf of the CROSS
program (cf. IAUC 7373), reports his discovery of an apparent supernova
(mag about 16.4) on two unfiltered CCD images (limiting magnitude about 19.0)
taken on Mar. 25.75 UT with the remote-controlled 0.28-m "GRAS15 telescope"
at Moorook, Australia; confirming images on Mar. 26.75 with this same
instrument and with the "Skylive 6" 0.35-m remote-controlled telescope
located at Grove Creek, Australia, show 2009bu at mag about 16.1.  The new
object is located at R.A. = 22h56m01s.40, Decl. = -63o41'39".6 (equinox
2000.0), which is about 18" east and 3" north of the nucleus of the galaxy
NGC 7408.   A CROSS image of the same field taken on 2008 Dec. 27.0 showed
nothing at this position (limiting mag about 18.5), and it does not appear on
Palomar Sky Survey infrared, red, and blue plates.  The discovery image has
been posted at http://www.cortinastelle.it/cross/NGC7408_20090325.jpg.
SN 2007bn also appeared in NGC 7408 (cf. CBET 940).
