SU URSAE MAJORIS
An appeal by Elizabeth Waagen for observations of SU UMa has appeared on
AAVSO Special Notice 413:

Deanne Coppejans (Department of Astrophysics, Radboud University Nijmegen)
requests observations of the dwarf nova SU UMa now in order to determine its
status. She and colleagues observed it on 2016 February 20 with the Very
Large Array (VLA) and need to know whether it is (was) in outburst.

Observations of SU UMa in the AAVSO International Database from around the
time of the VLA observations show it to be in quiescence: Feb. 17.8722 UT,
<13.7 (MUY, E. Mullyaert, Oostende, Belgium); Feb. 20.8181, <13.4 (OJR, J.
Ripero, Madrid, Spain); but the observations are sparse and there are no
observations between these two or since Ripero's of Feb. 20. Observations
prior to Muyllaert's confirm that SU UMa was in quiescence for at least
several days.

Two requests are being made now:

- Please observe SU UMa and report its status to the AAVSO. Time series are
not necessary. If SU UMa is in outburst, please monitor it until it has
returned to minimum.

- If you have recent observations of SU UMa, particularly from Feb.
17 to the present, please submit them to the AAVSO as soon as possible.

Coordinates: R.A. 08 12 28.28  Dec. +62 36 22.3  (2000.0)

Please submit your observations to the AAVSO International Database using
the name 'SU UMA'.

Editor: Please also report your observations to Gary Poyner for the next TA
magazine issue and also to the BAAVSS database.
