SUPERNOVAE 2009hf AND 2009hg
L. A. G. Monard, Pretoria, South Africa, reports his discovery of two
apparent supernovae on unfiltered CCD images taken at his Bronberg Observatory.
SN 2009 UT R.A. (2000.0) Decl. Mag. Offset
2009hf July 9.138 0 37 21.79 -19 56 42.2 17.2 2" E, 38" S
2009hg July 9.694 12 54 42.61 -39 51 16.3 16.9 28" W, 8" S
Additional magnitude estimates by Monard for 2009hf in the galaxy NGC 175:
June 24.105 UT, [18.5; July 10.110, 17.3. Additional magnitude estimates by
Monard for 2009hg in the SBcd-type spiral galaxy NGC 4767B (= ESO 323-41):
June 13.762, [18.8; July 10.715, 17.0. Nothing is visible at the positions
of 2009hf or 2009hg on Digitized Sky Survey images (limiting red mag 20.5).
