through 15 February, with 10 minutes (including
overhead) per exposure (5 min to acquire, 2.5 min comp, 2.5 min
exposure, including read-out)

telescope may yield the resolution to thoroughly probe the
optical variability of this "prototypical" LBV and resolve
some unanswered questions including, but not limited to:
are any of the secondary star's spectral features visible?
what is the variability of the unidentified emission feature
at 6307A at periastron? (currently only probed at apastron)
