Mark Kidger re= ports:
I have just received an alert from Mauri Valtonen at Tuorla Observatory=20 in Finland that the next outburst in the sequence of (approximately) 11=20 year outbursts of OJ287 appears to have started already. The most recent outbursts in this sequence were in 1972, 1983, 1995 & 2006.

Mauri asks for observations to help define the outburst. All contributions=20 are useful as this object has been observed to vary by a magnitude or=20 more in an hour.

Please communicate observations to me for compilation.

Thank you!
