  3C 454.3 outburst confirmed

  Nakajima-san also confirmed this outburst at V=13.8 on Aug 22.
Surprisingly enough, the color V-Rc = +0.34 was much bluer than
those of recent measurements.  The present "blue" continuum looks
like comparable to the intense 2005 outburst (V-Rc about +0.5 in
2005 May).
