SUPERNOVA 2015F IN NGC 2442 (MONARD)
2015F   Mar 09.78   07 36 15.76  -69 30 23.0  16.8  40  "W   84  "N 
Discovery on several unfiltered CCD images taken at Klein Karoo Observatory
with a 35-cm RCX400 telescope (+ SBIG ST8-XME camera).

M. Fraser et.al., on behalf of the PESSTO collaboration report that an
optical spectrogram obtained on Mar. 11.00UT with the 3.6-m New Technology
Telescope at La Silla, shows it to be a type-Ia supernova. The best fit to
the spectrum found via the SNID is to the spectrum of SN 2002bo at roughly
twelve days before maximum light.

SUPERNOVA 2015G IN NGC 6951 (SHIMA)
2015G   Mar 23.78   20 37 25.58  +66 07 11.5  15.5  68.7"E   51.4"N
Shima notes that nothing is visible at this position on red and blue images
from the Digitised Sky Survey.
Additional CCD magnitudes: Mar. 24.125, 15.9 (Denis Buczynski, Portmahomack,
U.K.; 35.6-cm reflector + SBIG ST9XE camera; position end figures 25s.58,
11".6); 24.540, V = 16.26, I_c = 15.89 (S. Kiyota, Kamagaya, Japan; remotely
with an iTelescope 0.61-m f/6.5 CDK astrograph + FLI PL09000 camera at the
Sierra Remote Observatory near Auberry, CA, USA; image posted at

31.056, 16.7 (G. Masi, remotely using a 43-cm telescope near Ceccano, Italy;
position end figures 25s.58, 11".6).

K. Ayani, Bisei Astronomical Observatory (BAO) spectrogram 
with the BAO 1.01-m telescope on Mar. 25.8 UT.  The spectrum is likely that
of a type-Ib supernova.  Cross- correlation with a library of supernova
spectra using the "SuperNova Identification" code SNID shows that the
spectrum best matches with spectra of type-Ib supernovae about a month past
maximum,
