(1) Restriction in the pointing due to the wind.

(2) Type II, similar to type IIP SNe such as SN1999gi, around 5-6 days after explosion (SNID & GELATO).

(3) Young type II (possible IIP) SN.

(4) Due to the short time left before the twilight, we could take only one spectrum of the two requested for this SN. We will try to get another one in the next days.

(5) We repeated the spectrum in order to collect a higher S/N
