SUPERNOVA 2008if IN MCG -01-24-10
     G. Pignata, J. Maza, M. Hamuy, R. Antezana, L. Gonzalez, P. Gonzalez, P.
Lopez, S. Silva, G. Folatelli, D. Iturra, R. Cartier, and F. Forster,
Universidad de Chile; B. Conuel, Wesleyan University; and D. Reichart, K.
Ivarsen, A. Crain, D. Foster, M. Nysewander, and A. LaCluyze, University of
North Carolina at Chapel Hill, on behalf of the CHASE project, report the
discovery of an apparent supernova (mag approximately 14.9 +/- 0.1) on a
Luminance-filter image taken on Dec. 12.21 UT with the 0.41-m 'PROMPT 2'
telescope located at Cerro Tololo.  The new object, which was confirmed at
mag 14.4 +/- 0.1 on a similar image taken on Dec. 16.18, is located at R.A.
= 9h20m23s.47 +/- 0".1, Decl. = -07o52'33".1 +/- 0".1 (equinox 2000), which
is about 22".4 east and 17" north of center of the galaxy MCG -01-24-10.
Nothing is visible at this position on archival images taken on Nov. 18.26
and Dec. 2.23 (limiting mag 18.0).  Following posting on the Central
Bureau's unconfirmed-objects webpage, S. Nakano (Sumoto, Japan) reports
that K. Itagaki (Yamagata-ken, Japan, 0.60-m f/5.7 reflector) obtained
an unfiltered CCD image (limiting mag 19.0) on Dec. 16.698 that shows
2008if at mag 16.0, measuring its position end figures to be 23s.48, 32".5.
