The individual images from Berry2 of ASASSN-V J170615.23-322944.7 and ASASSN-V J181654.06-202117.6 are really nice, and I see no need for as many images as in the plan for binning. I have no idea how "booked up" that system is, but I think I can return about 30 min per observing night to use for whatever else may be in queue without affecting the quality of the data I report out.

Both variables use the same exposure series: qty 5 B 180 sec exposures, qty 3 V 120 sec, qty 3 R 120 sec and qty 3 I 120 sec images.

I'd be comfortable backing down to Qty 2 B 180 sec, qty 2 V 120 sec, qty 2 R 120 sec and qty 2 I 120 sec images.

If you think this is a good idea I'll make that note on the 185 and 186 proposal forms by Monday.
All the Best,
Peter
