Observing Campaign #797: Monitoring requested for V730 Cep

View here: Details for Monitoring requested for V730 Cep

Abstract: AAVSO Young Stellar Object (YSO) Section leader Michael Poxon (Great Plumstead, Norfolk, UK) requests coverage of the YSO V730 Cep beginning immediately and continuing until further notice.

Justification: Following a series of deeper than usual fades on the Herbig B star V730 Cephei (most recently to magnitude 16.1 visual, 16.3B) it would be good to have as ‘wide a wavelength as possible’ coverage of this object at all stages of its behaviour, especially at times leading up to, as well as just after, any fades that take place. Fades are typically sudden and are becoming increasingly deep. In view of the above, observations using a variety of filters over a period of several fades, as well as purely visual observations, are needed to form a more complete picture of the star and its environment.

Is this campaign over at the end of August 2025? We’ve been following it (in V) with our telescope in Spain (Astronomical Society of Edinburgh) since December last year, watching the outbursts and a recent deeper dip. Is anyone going to use the data for some purpose now?

Cheers
Mark
