The 5-day Suzaku (X-ray) observation has started, and it would be great
if you obtained (necessarily) short time series during this week. And
if possible, specify your comparison star and its magnitude (we'd like
it to be calibrated, for a change).
Nothing dramatic may occur, but probably one "echo outburst" will be
resolved. That's the main goal of the observation - so finish up the
V1159 Ori season with a flurry!
SDSS J0902+3819 will probably be the star of the week if it stays
bright. Maybe even the star of the year - AM CVn stars are rare, and
their superoutbursts are mighty hard to catch.
Time to quit on BK Lyn - it seems to be pretty stable this year... in a
"standstill", to use the Z Cam terminology. We can also quit on AM CVn
- the coverage has been so good that all the periods and phases are
determined very, very precisely. CR Boo and HP Lib would be worthy
successors, though. For some reason (the Galactic pole?), practically
all the AM CVn stars are in the (northern) springtime sky.
