RX And monitoring needed for VLA observations
AAVSO Special Notice #418July 5, 2016
RX And monitoring needed for VLA observations
Further to AAVSO Alert Notice 539
(https://www.aavso.org/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."
This thread may be followed at
https://www.aavso.org/northern-dwarf-novae-campaign
Observers are asked to monitor RX And from now through at least
the end of July. Observers will be notified when the VLA
observations have been made and the campaign is concluded - please
continue your observations until then. High-cadence monitoring is
not needed; nightly observations are sufficient to determine
whether RX And is in outburst or quiescence. Two observations
(widely spaced) per night would be helpful.
Coordinates for RX And: R.A. 01 04 35.52Dec. +41 17 57.8
Charts with comparison stars for RX And may be created using the
AAVSO Variable Star Plotter (VSP, http://www.aavso.org/vsp).
Please report observations to the AAVSO International Database
using the name RX AND.
This campaign is being followed on the AAVSO Observing Campaigns
page at https://www.aavso.org/observing-campaigns.
