Campaign on six nova-like variables

Chandra went into safe mode today. Depending on the cause and on how long Chandra will be down, Dr. Mukai's campaign may be impacted. Since we don't know how long (or short) the interruption may be, please continue to take a few snapshots of KQ Mon during the observing window this week and through the end of October.

We'll keep you posted of further developments via this forum.

Many thanks, and Good observing,

Chandra is operational again, but the observation of KQ Mon has been postponed to a future date to be determined.  So for now, an occasional snapshot of KQ Mon is all that is needed, as for the other stars in the campaign (AN 652).

Many thanks, and Good observing,

AAVSO Alert Notice 659 reports that KQ Mon, one of the novalike variables to be observed with Chandra in Dr. Koji Mukai's campaign (AAVSO Alert Notice 652), has been scheduled for observation with Chandra 2019 January 29-30 UT. Please see Alert Notice 659 for details and observing instructions.

In AAVSO Alert Notice 659 on KQ Mon being observed with Chandra, the dates were correct (January 29/30) but the times were wrong. AAVSO Alert Notice 661 gives the corrected time as well as other pertinent information. My apologies for the error!

Good observing,

AAVSO Alert Notice 663 reports that 1SWASP J022916.91-395901.4, one of the novalike variables to be observed with Chandra in Dr. Koji Mukai's campaign (AAVSO Alert Notice 652), has been scheduled for observation with Chandra 2019 March 11-12 UT. Please see Alert Notice 663 for details and observing instructions.

AAVSO Alert Notice 674 reports that UU Aqr, the sixth and final of the novalike variables to be observed with Chandra in Dr. Koji Mukai's campaign (AAVSO Alert Notice 652), has been scheduled for observation with Chandra 2019 August 3 UT. Please see Alert Notice 674 for details and observing instructions.

Dear AAVSO observers,

Thank you very much for your interest in my campaign to observe 6 nova-like variables with Chandra. The X-ray campaign is now complete - all six of my approved targets have now been observed. I haven't had the time for a proper analysis of the data yet - that will take at least several months. However, the observations all apper to have been successful, judging by the quick-look images provided by the Chandra folks with the data.

For all six of these objects, you have provided enough optical data to place the X-ray data in proper context. So, in that sense, your part in my campaign is over.

Except that UU Aqr, the object that was just observed a few days ago with Chandra, seems to be doing something interesting in the optical (several tenths of a magnitude decline over the last several months, I think some of the low points must be the eclipses?). It might be interesting to keep an eye on this objects through the resto f the observing season.

Thanks again - when I have some results, I'll post again in this forum.

Koji Mukai
