This Alert Notice is a preliminary announcement of upcoming campaigns on the recurrent nova T Pyx and a request for monitoring in advance of and in support of those campaigns.

Dr. Patrick Godon (Villanova University) has informed us that T Pyx will be observed by HST in the coming months to obtain far ultraviolet and optical spectra. Dates have not yet been announced. Additional Alert Notice(s) will be issued when the schedules for HST are available.

Beginning now until further notice, please observe T Pyx in V one to two times per night; V is preferred to other filters or unfiltered. Visual observations are welcome.

Please submit observations as soon after making them as possible to the AAVSO International Database. If T Pyx appears to be going into outburst, report observations immediately and email AAVSO ( T Pyx is around magnitude 15.5 V at minimum, and can brighten to magnitude 6 in outburst. Observations brighter than 14.0-14.5 should be treated as a possible outburst beginning.

Coordinates:  R.A. 09 04 41.51   Dec.  -32 22 47.6   (2000.0) (from the VSX page for T Pyx)

Charts with a comparison star sequence for T Pyx may be created using the AAVSO Variable Star Plotter (VSP).

Please submit observations to the AAVSO International Database using the name T PYX.

This AAVSO Alert Notice was compiled by Elizabeth O. Waagen using material provided by Dr. Godon.
