Di Mille, Universita di Padova, on behalf of the 'RTN Winter School on Supernovae' in Asiago, reports that a noisy spectrum (range 390-815 nm, resolution 2.3 nm) of SN 2005ab (cf. IAUC 8478), taken on Feb. 9.00 UT with the Asiago 1.22-m telescope (+ Boller & Chivens spectrograph), is that of a type-II supernova shortly after explosion. The spectrum consists of a blue continuum overimposed by a relatively broad (5400 km/s) H_alpha emission line."
