ETA CARINAE
J. C. Martin, University of Illinois at Springfield et. al., report on 
IAUC 8961 the first definite sign of eta Car's next spectroscopic event 
that is predicted to occur in 2009 January. Broad He II 468.6-nm 
emission has appeared in blue and red Gemini/GMOS spectra obtained on 
2008 July 4 and 17. The central velocity is near -40 km/s heliocentric, 
the FWHM is roughly 300 km/s, and the equivalent width is about 0.01 nm. 
In eta Car (HD 93308), this very-high-excitation feature becomes 
detectable only near a spectroscopic event, and it did not appear in 
similar data obtained during 2007 June-July and 2008 February.
No existing model clearly predicts its appearance as early as six months 
before the oncoming event.

35.6-cm Schmidt-Cassegrain telescope of the Tavolaia Observatory (Santa 
Maria a Monte, Pisa).
The new object is superimposed on a faint H II region that is visible on 
two red Palomar Sky Survey (POSS) plates.
Independent discovery was made by LOSS.

A. Harutyunyan and S. Benetti, Istituto Nazionale di Astrofisica,
Osservatorio Astronomico di Padova et. al. report that a spectrum
obtained on July 16.08 UT with the 3.5-m TNG shows it to be a type-
Ia supernova a few days before maximum light.
