The following proposed informal Pro-Am campaign has been posted on the ConVento forum By Noel Richardson University of Montreal. These are very bright easy objects for LHIRES or eShel - ideal for the short summer nights ! I have attached the document referred to (zipped pdf) The discussion continues on the Pro-Am ConVento group.

Hi all,

The massive star folks in Montreal are happy to announce that the BRITE
nanosatellites will be obtaining continuous, millimag-precision
photometry for about 6 months starting in the next few weeks. We would
like to suggest an informal campaign to obtain high-quality spectra of
two of the most luminous supergiants in the Galaxy simultaneous to the
high-precision photometry. The stars are Deneb and P Cygni. I've
attached a little write-up of the project below.

Thank you for your help and support!

Noel Richardson

Before the background of the planed collaboration with the BRITE science team (namely Noel Richardson, Montreal/Canada), here the current observation results of the Halpha EW. It seems, that we have detected a period of approx. 200 days (roughly estimated; also found by Markova), but with different depths of EW.
It would be great, if we could cover that behavior with a high observation density the next weeks and months, particularly during the OHP workshop.
