BF CYGNI
T. Iijima, Astronomical Observatory of Padova, Asiago Station,
reports on CBET 1351 that, following the announcements of a brightening 
of the symbiotic star BF Cyg via AAVSO and VSNET alerts, a high 
dispersion spectrogram was taken on Apr.20.146
UT with an echelle spectrograph mounted on the 182-cm telescope at the 
Mount Ekar station of the Astronomical Observatory of Padova. Spectra in 
the last observational season (Nov. 2007) showed numerous emission lines 
of H I, He I, Fe II, [Fe II], [N II], Na I, etc.  In contrast to them, 
the emission lines of He I, [Fe II], and [N II] have disappeared in the 
new spectrum, and the other lines have fairly weakened. These features 
confirm that BF Cyg has entered a new explosive stage.

SUPERNOVA 2008by IN ANONYMOUS GALAXY
Discovery by ROTSE collaboration of a possible supernova (CBET 1350):
SN      2008 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2008by  Apr. 19.21  12 05 20.98  +40 56 45.6  17.2     1.9"E, 1.2"N
Spectroscopy obtained on Apr. 22.10 with the 9.2-m Hobby-Eberly
Telescope by S. Rostopchin and V. Riley, shows it to be a type-Ia 
supernova.
