SPECIAL AAVSO ALERT NOTICE ON DWARF NOVAE
Do continue your close monitoring of dwarf novae. Dr. Stiening from Stanford University and his colleagues will be observing these stars from Nov. 25th to Dec. 4th at Mt. Lemon, Arizona, and they have requested our help once again.

AAVSO ALERT NOTICE 172 (April 22, 1993)
1908+01 NOVA AQUILAE 1993 [V1419 AQL]
April 5, 2016: Further to AAVSO Alert Notice 536, close monitoring of the cataclysmic variable SS Cyg is urgently requested. Immediate notification of the beginning of the anticipated outburst is crucial and is requested.
The success of the multiwavelength (radio and optical) observing campaign on SS Cyg underway depends on immediate reporting of outburst behavior to trigger multi-site radio observations.

2337+56 NOVA CASSIOPEIAE 1993 [V705 Cas]
This bright nova, discovered on December 7.47 UT by Syuichi Nakano of Japan at photographic magnitude 6.5 (see AAVSO Notice 179), has been very well monitored by observers worldwide. Its optical light curve, created from observations reported to the AAVSO, indicates it brightened to about visual magnitude 5.7 by mid·Oecember, and then has slowly declined to magnitude 8.4 by February 7, with fluctuations as much as 1 magnitude in amplitude.

2337+56 NOVA CASSIOPEIAE 1993 [V705 Cas]
February 8, 2016: Further to AAVSO Special Notice #412, Dr. James Miller-Jones (International Centre for Radio Astronomy Research, Curtin University, Perth, Western Australia) and colleagues have requested AAVSO assistance in support of their multiwavelength (radio and optical) campaign on the dwarf nova SS Cyg. Close monitoring of SS Cyg and immediate reporting of observations to the AAVSO via WebObs is requested beginning now.
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.
