RX And observations needed urgently now
AAVSO Special Notice #423October 11, 2016
RX And observations needed urgently now
Further to AAVSO Alert Notice 549
(https://www.aavso.org/aavso-alert-notice-549), observations of
the dwarf nova RX And are urgently requested immediately. The
system *may* be going into outburst, and confirmation is essential
in order to know whether to trigger ToO observations with Chandra
and other instrumentation.
Dr. Christian Knigge (University of Southampton) and colleagues
need to catch RX And as early in this outburst as possible. It
would be the first narrow outburst following a wide outburst, so
would meet their criteria for ToO observations.
Please observe RX And as soon just as soon as it is in your viewing
reach and report your observations immediately to the AAVSO using
WebObs.
Coordinates (2000.0):R.A. 01 04 35.52Dec. +41 17 57.8

created using the AAVSO Variable Star Plotter (VSP) at

Please submit observations to the AAVSO International Database
using the name RX AND.
