Observations of CI Cam needed to support spectroscopy
Active Dates: Oct. 19, 2016 – Jan. 31, 2017
Abstract:
Kelly Gourdji and Marcella Wijngaarden (graduate students at the University of Amsterdam/Anton Pannekoek Institute for Astronomy) have requested AAVSO observers' assistance in providing optical photometry of CI Cam in support of their high-resolution spectroscopy with the Mercator telescope + Hermes spectrograph in La Palma.
Justification:
They are observing the variable star CI Cam with the HERMES spectrograph and have detected the object in outburst, similar to the previous outburst in 2004/5. Photometric data obtained during the 2004/5 outburst suggested an outburst duration of about 3 months and a peak brightness of 11.2 in the V band.
