Special Notice #412: SS Cyg monitoring needed for radio campaign

February 4, 2016:  A multiwavelength (radio and optical) observing campaign on SS Cyg is underway, and AAVSO participation is urgently requested. An AAVSO Alert Notice will be issued February 5 with full details.

The purpose of this Special Notice is to alert observers right now to the need to monitor SS Cyg very closely and report your observations to the AAVSO via WebObs at once. It is likely to go into outburst very soon, and immediate reporting of outburst behavior is crucial to the success of the campaign.
