M. Salvo and P. Price, Research School of Astronomy and Astrophysics, Australian National University (ANU), report that a spectrum (range 340-920 nm, resolution about 0.4 nm) of SN 2002ed taken at the ANU 2.3-m (+ Double Beam Spectrograph) at Siding Spring Observatory on July 30.41 UT shows it to be similar to the type-IIP SN 1992H at early phases, according to the spectra published in Clocchiatti et al. (1996, A.J. 111, 1286) and shows a blue continuum with a broad H-alpha emission and H-beta with a P-Cyg profile. The expansion velocity measured from the blueshifted minimum of H-beta is about 11 500 km/s, adopting the NED recession velocity of 2845 km/s for the host galaxy.
