T Pyx monitoring requested for upcoming HST observations
Active Dates: Feb. 28, 2023 – April 7, 2023
Abstract:
Dr. Patrick Godon (Villanova University) requests AAVSO observers' assistance in monitoring the recurrent nova T Pyx, beginning immediately, in support of upcoming HST ultraviolet and optical spectroscopic observations scheduled for March 20-21, 2023. These observations are the first of two sets planned this year for T Pyx.
Justification:
Monitoring T Pyx and knowing its status is essential to be sure that it has not gone "...into outburst during (or before) the HST observations. When in outburst...T Pyx can reach V=6 or so! Such a flux would destroy the detectors of HST and grill some of its hardware. AAVSO observations will also reveal whether other unusual source fluctuations occur.
