Note: This campaign is officially over, but the astronomers would appreciate it very much if observers could make an occasional observation of PDS 110. EOW March 29, 2018
Note: This Alert Notice was edited to add the magnitude range of PDS 110. EOW
From our observers, featuring Jessica Johnson (JJMA):
December 2, 2016: An AAVSO campaign on the bright star b Per has been launched at the request of Dr. Donald F. Collins, who writes:
Some of the best opportunities for contributing to astronomical research come through the AAVSO's Observing Campaigns, which are observing projects requested by individual researchers with a specific goal in mind. Some Campaigns are designed to last for a long time, and the results aren't known until well after the campaign concludes. But some campaigns pay off immediately. Our campaign on the bright star b Persei is an example of the latter, with a handful of AAVSO observers getting exactly the right data, at the right time, right away!
January 16, 2015: We have been informed by PI Dr. Matthew Muterspaugh that his campaign on alpha Com (AAVSO Alert Notice 506) has been cancelled. Position measurements published a century ago contained errors that affected the predictions for the time of eclipse.
More information will be coming from Dr. Muterspaugh and we will disseminate it to everyone in an Alert Notice, but he asked that the observer community be informed now so that observing efforts might not be wasted.
January 16, 2015: THIS CAMPAIGN HAS BEEN CANCELLED. PLEASE SEE AAVSO SPECIAL NOTICE #395 FOR DETAILS.
December 5, 2014: Drs. Matthew W. Muterspaugh and Gregory W. Henry (Tennessee State University) have requested AAVSO observers' assistance in monitoring the possible Algol-like binary star alpha Com before, during, and after the eclipse they have predicted for mid-to-late January 2015.
