SUPERNOVA 2008bo IN NGC 6643
     Markku Nissinen, Varkaus, Finland, reports the discovery of an apparent
supernova (mag 16.6) on unfiltered and Bessel-R-band CCD images (limiting
unfiltered mag 19.5) taken over two hours, obtained by Veli-Pekka Hentunen and
himself with a 30.5-cm Meade LX200 f/10 telescope (+ SBIG ST8-XME camera)
beginning at Mar. 31.92 UT at Taurus Hill Observatory, Karhilantaipaleentie;
a confirming image on Apr. 1.827 yields R = 16.6 for 2008bo.  The new object
is located at R.A. = 18h19m54s.34, Decl. = +74o34'20".9 (equinox 2000.0),
which is 31" east and 15" north of the center of NGC 6643.  Nothing is visible
at this position on a Palomar Sky Survey red image (limiting mag 20.8).  A.
Oksanen, Muurame, Finland, adds that his unfiltered CCD exposures taken with a
40-cm telescope on Apr. 1.050 and 2.788 yield red magnitudes 16.5 and 16.3,
and position end figures 54s.40 +/- 0s.02, 21".4 +/- 0".2 for 2008bo;
Oksanen's image from Apr. 1 is available at the following website URL:
