[size=13.3333px]RX And monitoring needed for VLA observations


[size=13.3333px]Further to AAVSO Alert Notice 539
[size=13.3333px]([size=13.3333px]https://www.aavso.org/aavso-alert-notice-539[size=13.3333px]), Deanne Coppejans
[size=13.3333px]and colleagues request optical monitoring of the Z Cam dwarf nova
[size=13.3333px]RX And in support of their campaign to observe it with the Very
[size=13.3333px]Large Array (VLA) in their ongoing radio jet research.

[size=13.3333px]Deanne writes in a post to the AAVSO Forum thread on this campaign:
[size=13.3333px]"We are going to try and catch RX And in quiescence again in the
[size=13.3333px]next three weeks. The optical coverage of it is still sparse, so
[size=13.3333px]any observations you take of it will be extremely useful."

[size=13.3333px]https://www.aavso.org/northern-dwarf-novae-campaign

[size=13.3333px]Observers are asked to monitor RX And from now through at least
[size=13.3333px]the end of July. Observers will be notified when the VLA
[size=13.3333px]observations have been made and the campaign is concluded - please
[size=13.3333px]continue your observations until then. High-cadence monitoring is
[size=13.3333px]not needed; nightly observations are sufficient to determine
[size=13.3333px]whether RX And is in outburst or quiescence. Two observations
[size=13.3333px](widely spaced) per night would be helpful.

[size=13.3333px]Coordinates for RX And: R.A. 01 04 35.52  Dec. +41 17 57.8

[size=13.3333px]Charts with comparison stars for RX And may be created using the
[size=13.3333px]AAVSO Variable Star Plotter (VSP, [size=13.3333px]http://www.aavso.org/vsp[size=13.3333px]).

[size=13.3333px]Please report observations to the AAVSO International Database
[size=13.3333px]using the name RX AND.

[size=13.3333px]This campaign is being followed on the AAVSO Observing Campaigns
[size=13.3333px]page at [size=13.3333px]https://www.aavso.org/observing-campaigns[size=13.3333px].
