V5587 SAGITTARII = NOVA SAGITTARII 2011
Further to TA E-Circulars 2708 and 2712, IAU Circular 9196 giving the 
full discovery details was lost in transmission to us but contained a 
new designation of V5587 Sagittarii.

SUPERNOVA 2011A IN NGC 4902 (CHASE)
2011A   Jan   2.30  13 01 01.19  -14 31 34.8  16.9  21.3"E,  46.5"S
SNe 1979E and 1991X also appeared in NGC 4902.
M. Stritzinger, Oskar Klein Centre, Stockholm University et. al., report 
that they obtained optical spectra on Jan. 4.2 and
4.7 UT with the du Pont telescope (+ WFCCD) and the Gemini North 
telescope (+ GMOS).  This variable appears to be a type-IIn supernova, 
most similar to supernova 2005cl.

SUPERNOVA 2011B IN NGC 2655 (Itagaki see TA E-Circular 2709)

SUPERNOVA 2011C IN UGC 6311 (CHASE)
2011C   Jan   5.30  11 17 54.88  -02 05 45.2  15.8   1.4"W,  14.4"S
Dave Balam, Dominion Astrophysical Observatory, National Research 
Council of Canada et. al., report that a spectrogram obtained on Jan. 
8.58 UT with the 1.82-m Plaskett Telescope of the National Research 
Council of Canada, shows it to be a type-Ia supernova, then about one 
week past maximum light.  Cross-correlation with a library of supernova 
spectra indicates that 2011C is most similar to the type-Ia supernova 
2003cg at 6 days past maximum.
