 Mis V1448: second rebrightening since 20th Nov.

Kyoto U. team, Osaka Kyoiku U. team, Itoh-san, Tamas Tordai, and Crimean
Astrophys. Obs. team have reported observations for Mis V1448.

Observations on 20th Nov. by Itoh-san and Tamas show another
rebrightening reaching around 14 mag, which is the same as the first
rebrightening.

This object still shows a prominent superhump with an amplitude of 0.5 mag.

More continuous observations are encouraged!
