Dear SN watchers,
The recent report of the magnitude of SN 2002ao suggest that it has
experienced sudden and large amplitude fading in these days.
20020128.708 14.96Ic (Seiichiro Kiyota)
20020129.183 148CR (Jean Marie Llapasset)
20020129.197 136 (Jose Ripero)
20020205.036 138 (Maciej Reszelski)
20020208.131 162CR (J. Nicolas)
, and Llapasset informed that she confirmed the fading, and it is
163CR on Feb. 13.
Such fading is very unusual for supernovae, and it will be able to
explain the dramatic change in the spectra, or the uncertain nature of
this SN. Further observation with any technique are highly
recommended.
Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
