SUPERNOVA 2005dh IN MCG +04-37-55
     M. Salvo, B. Schmidt, T. Davis, and S. Sankarankutty, Australian
National University (ANU), report that a spectrum (range 350-900 nm),
obtained on Aug. 15.40 UT with the ANU 2.3-m telescope (+ Double-Beam
Spectrograph), shows SN 2005dh (IAUC 8583) to be a type-Ia supernova
near maximum light.  Adopting the NED recession velocity for the host
galaxy (from the RC3 Catalogue) the expansion velocity of the Si II
635.5-nm line is around 16600 km/s.
