Abstract (from CDS):

N. Elias-Rosa and S. Benetti, Osservatorio Astronomico di Padova;, V. Stanishev and A. Goobar, Stockholm University; and A. Jaervinen, Nordic Optical Telescope (NOT), on behalf of the 'ERTN' (cf. IAUC 7987), report that inspection of a spectrum (range 320-910 nm, resolution 1.7 nm), obtained on Mar. 10.01 UT with the NOT (+ ALFOSC) at La Palma, that SN 2004aq is a type-II supernova, about 1 month after explosion. The spectrum is dominated by P-Cyg lines of H, Ca II, and Fe II overimposed on a relatively blue continuum (T_bb about 8000 K). The expansion velocities deduced from the H_alpha and H_beta absorptions are about 7700 and 6500 km/s, respectively.
