...by Swift will take place October 16 from 1:26 UT to 9:15 UT. Nicely
timed for Europe and the Americas, except that it's MIGHTY SOON. That's
Thursday night, in USA-speak. Truly simultaneous observation would be
just great - and should probably be white light, since statistical
accuracy is of paramount importance in analyzing for correlations. But
anything within a few days is close enough to be "contemporaneous", and
has heightened value also.
Good luck! The star's brightness seems to be jumping around in the last
few days; the snapshot magnitudes are kind of confusing. If you have
clear skies and a V filter, be sure to get a (decently, not fanatically)
calibrated V magnitude in there somewhere, so our time series don't have
a large zero-point uncertainty.
Koji Mukai secured this time, and points out that a new gamma-ray burst
would bump us off the schedule. May our skies be quiet and clear.
