August 3, 2016: Dr. Noel Richardson (University of Toledo) and colleagues have requested AAVSO assistance in optical monitoring of the bright, colliding-winds binary V1687 Cyg (WR 140, HD 193793) as part of their multi-wavelength campaign on this system.
July 13, 2016: Dr. Colin Littlefield (University of Notre Dame) and colleagues Drs. Peter Garnavich (Notre Dame), Erin Aadland (Minnesota State), and Mark Kennedy (University College Cork) have requested AAVSO assistance in monitoring the intermediate polar cataclysmic variable FO Aqr beginning immediately.
Dr. Littlefield, who with his colleagues recently published ATel #9216 and #9225, writes:
July 5, 2016: Further to AAVSO Alert Notice 539, Deanne Coppejans and colleagues request optical monitoring of the Z Cam dwarf nova RX And in support of their campaign to observe it with the Very Large Array (VLA) in their ongoing radio jet research.
Deanne writes in a post to the AAVSO Forum thread on this campaign: "We are going to try and catch RX And in quiescence again in the next three weeks. The optical coverage of it is still sparse, so any observations you take of it will be extremely useful."
