La prima SUPERNOVA scoperta dal TEAM

supernova 1996 AE in ngc 5775

La seconda SUPERNOVA scoperta dal TEAM (Di Silvano Romanelli)

supernova 2004 DG ngc 5806

................. E la supernova mancata............peccato!! .......

discovery ST6-CCD image (negative) of SN1995F in NGC 2726, taken by David Lane, Paul Gray, and Beverly Miskolczi of Saint Mary's University and the Halifax Centre, Royal Astronomical Society of Canada on the evening of February 10, 1995. The supernova is the dark spot near the centre of the galaxy. It's discovery magnitude was about 15 and was too faint to observe visually through all but the most gigantic amateur telescopes.

IAU Circular on Supernova 1995F in NGC 2726

D. J. Lane and P. Gray, Burke-Gaffney Observatory, Saint Mary's University, report their discovery via CCD on Feb. 10-11 of a supernova located about 2" east and 1" south of the center of NGC 2726 (R.A. = 9h04m.9, Decl. = +59o56', equinox 2000.0). An unfiltered frame on Feb. 14.042 UT showed the object at mag 14.7. A foreground star of mag 14.9 is located 19".6 west and 14".9 south of SN 1995F. A. V. Filippenko and A. J. Barth, University of California at Berkeley, report that preliminary inspection of uncalibrated CCD spectra (range 310-1050 nm, resolution 0.7-1.5 nm) obtained on Feb. 24 with the 3-m Shane reflector at Lick Observatory confirms that this object is a supernova, most likely of type Ic (but possibly Ib), roughly 2-3 weeks past maximum brightness.

SUPERNOVA 1995F IN NGC 2726
A. Vagnozzi, G. Piermarini, and V. Russo, S. Lucia Observatory,
Stroncone, Italy, report the following precise position for SN
1995F from a pre-discovery CCD image obtained on Feb. 6.918 UT,
when the object's unfiltered magnitude was 14.3 (derived using GSC
comparison stars): R.A. = 9h04m57s.40, Decl. = +59o55'58".7 (
equinox 2000.0).
