May 11, 2006: Daniel W. E. Green, Central Bureau for Astronomical Telegrams, reports (IAU Circular 8709) the discovery by L. A. G. Monard, Pretoria, South Africa, of a bright apparent supernova in NGC 908 (Cetus) at unfiltered CCD magnitude 12.4 on images taken May 10.14 UT using a 0.30-m reflector. Monard reported nothing was visible at the location of SN 2006ce on the Digitized Sky Survey (limiting mag 20.5 R) or on his images taken prior to April 1 (limiting mag ~18).
Monard gives the following position for SN 2006ce, which is offset 136" West and 28" South of the nucleus of NGC 908:
R.A. 02:22:54.63 Decl. -21:14:29.4 (2000)
Aditional observations from Monard: Apr. 1.713 UT, (16.5 R; May 11.151, 12.9 B, 12.55 V, 12.4 R. Please note that this supernova is presently observable only during dawn twilight. Observers are encouraged to follow its outburst and decline as observing becomes more feasible. Please observe visually or photometrically with a B, V, and/or Ic filter.
