OJ 287 NEW OUTBURST
Mark Kidger reports (further to TA E-Circular 3142):
After reaching R=12.85 on 2015 December 5, the light curve of the blazar
OJ287 has shown a downward trend, punctuated by flaring activity, reaching a
minimum of R=15.0 on 2016 February 4/5. 

A new, rapid brightening started on 2016 February 6, being detected, among
others, by Gary Poyner, David Boyd and Ramon Naves and Montse Campas. This
peaked on February 16 at R=13.45. Yet another rapid and continuous
brightening started on February 28. At 23:48UT on March 3 Naves and Campas
measured R=13.15, with the upward trend still continuing (see ATel 8768). It
is possible that this maximum may surpass the peak of early December 2015.

MASTER OT J084140.94+722732.6 (=NSV 4186)
Further to TA Circulars 3147 and 3149, Roger Pickard notes that the
suggested link to NGC 4186 quoted from ATEL 8731 should read NSV 4168.
