TT Ari monitoring requested for VLA observations
Active Dates: Dec. 3, 2017 – Dec. 19, 2017
Abstract:
Dr. Deanne Coppejans (Northwestern University) and colleagues have requested AAVSO assistance in monitoring the cataclysmic variable TT Ari in support of observations scheduled to be made with the Very Large Array (VLA) in December 2017.
Justification:
In preparation for these observations, we ask for increased monitoring of TT Ari over the period 3 - 19 December so that we know the state during the observations. Additionally, during the VLA observations, we need as many observations as possible (in any filter). If you are able to take photometry (as high cadence as possible) in a single filter, that will be extremely useful. V-band data are preferred. Otherwise, U-band if possible, or else any other band.
