March 1, 2016: Ms. Deanne Coppejans (PhD candidate, Radboud University Nijmegen (Netherlands) and University of Cape Town) and colleagues have requested AAVSO observer assistance in monitoring several northern dwarf novae in support of their campaign to observe them with the Very Large Array (VLA) in their ongoing radio jet research. Their research on radio jets in dwarf novae has been discussed in AAVSO Alert Notice 505.
December 2, 2014: AAVSO Alert Notice 505 (http://www.aavso.org/aavso-alert-notice-505) announced the campaign on several northern dwarf novae by Deanne Coppejans and colleagues. This campaign, searching for radio jets in dwarf novae, has been moving very quickly! Thanks to your observations and timely notifications, three of the five sets of VLA observations available for the targets have been used on Z Cam, RX And, and YZ Cnc. The PI is extremely appreciative and thanks you all for your excellent work.
