Kerzendorf, Australian National University (ANU), report that a spectrogram (range 360-950 nm) of 2006ci in ESO 182-G10 (cf. IAUC 8713), obtained on June 6.57 UT with the ANU 2.3-m telescope (+ DBS), shows features typical of a type-II supernova approximately 1 month past maximum light. The velocity of the photosphere, measured from Fe II 501.8-nm, is 7800 km/s -- assuming that the object's redshift is 3549 km/s (Di Nella et al. 1996, A.Ap. Suppl. 118, 311) -- which is a relatively high velocity for a supernova of this age. A spectrogram of SN 2006ce in NGC 908 (cf. IAUC 8709), obtained on June 6.83 UT, shows features typical of a type-Ia supernova; cross-correlation with a library of spectra indicates that the object is approximately 35 +/- 5 days past maximum light.
