Outburst of 2328+48 Z Andromedae and Request to Monitor 2138+43 SS Cygni and 1813+49 AM Herculis
Abstract:
The prototype of the symbiotic class of variable stars, Z And, is undergoing an outburst, the first such since September 1985. There are also requests to monitor the dwarf nova cataclysmic variable SS Cyg and the magnetic variable AM Her for their respective observations.
Justification:
To catch the symbiotic star Z And in its outburst phase and to trigger satellite observations for SS Cyg and AM Her when they show specific brightness changes.
Requested Data Types:
Spectroscopy, Photometry
