Patat, ESO, on behalf of the ERTN (IAUC 7987), report, from inspection of spectra obtained on Jan. 21.15 UT with the Calar Alto 2.2-m reflector (+ CAFOS; range 380-880 nm; resolution 1.1 nm), and Jan. 21.18 with the Asiago 1.8-m telescope (+ AFOSC; range = 355-780 nm, resolution 2.4 nm), that SN 2004G (IAUC 8272) is a type-II supernova, about 5 months after explosion. The expansion velocities deduced from the H_alpha and H_beta absorptions are about 6600 and 4300 km/s, respectively.
