R Aqr coverage needed for HST and Chandra observations
Abstract:
Dr. Margarita Karovska (Harvard-Smithsonian Center for Astrophysics) has requested visual, photometric, and spectroscopic observations of the symbiotic variable R Aqr in preparation for and in support of Chandra and HST observations currently scheduled for October 2017.
Justification:
The aim of the multiwavelength observations of this fascinating object is to study the physical characteristics of this system and including the multi-scale components of the powerful jet, from the central binary region to the jet-circumbinary material interaction region and beyond. AAVSO observations are requested in order to monitor the state of the system and correlate with the satellite observations. This [level of coverage] will provide solid optical data crucial to interpreting the satellite data.
Requested Data Types:
Photometry, Spectroscopy
