September 27, 2018: Dr. Ed Sion (Villanova University) requests AAVSO observers' assistance in monitoring the recurrent nova T Pyx, beginning immediately, in support of upcoming HST observations.
The HST COS observations have been scheduled to take place during the window of 2018 October 4 - 6. It is essential to know the status of T Pyx in order for the HST team to safeguard the instrumentation and make a final decision about approving the COS observations.

September 10, 2011: The outbursting recurrent nova T Pyx is past solar conjunction and is widely observable again. Arto Oksanen in Finland has been following it through July and August and reports it currently at 10th magnitude. Please add T Pyx back to your observing schedule if possible to follow the decline of its outburst.
Continued close monitoring of T Pyx requested
June 30, 2011: Since its outburst on 2011 April 14 (see AAVSO Alert Notice 436), the recurrent nova T Pyx has been very well monitored by visual and instrumental observers who can reach -32o. Thank you! Currently T Pyx is visual/V magnitude ~8.3.
