SUPERNOVA 2008ie IN NGC 1070
     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 16.4 +/- 0.2) on an
R-band image taken on Dec. 15.16 UT with the 0.41-m 'PROMPT 4' telescope
located at Cerro Tololo.  The new object, which is also present at mag
approximately 17.1 +/- 0.3 in an image taken on Dec. 6.17, is located at R.A.
= 2h43m20s.80 +/- 0".1, Decl. = +4o58'19".1 +/- 0".1 (equinox 2000), which is
about 22" west and 13" north of center of the galaxy NGC 1070.  Nothing is
visible at this position on archival images taken on Nov. 19.11 and 26.12
(limiting mag 18.0).
     S. Nakano, Sumoto, Japan, reports the independent discovery of 2008ie
at mag 16.9 by Yoji Hirose (Tsutsumi, Chigasaki, Kanagawa-ken, Japan) on
fourteen unfiltered CCD frames (limiting mag 17.5) taken around Dec. 15.56
UT using a 0.35-m f/6.8 Schmidt-Cassegrain telescope.  Hirose provided
position end figures 21s, 20", with offset 13" west and 15" north of the
center of the galaxy.  Nakano measured a JPEG image supplied by Hirose,
finding position end figures 20s.84, 19".2 for 2008ie, corresponding to
21" west and 12".5 north of the center of NGC 1070.  Nothing is visible at
this position on Hirose's survey frames taken on Nov. 20 (limiting magnitude
18) and Dec. 3 (limiting magnitude 17.5) or on the Digitized Sky Survey.
