This semester the Tufts University introduction to astronomy class observed epsilon Aurigae as their course lab. The class has around 250 students and they do not have access to equipment for a formal lab. So epsilon Aurigae was perfect since it is bright enough to be seen from campus with the unaided eye and happens to be emerging from the eclipse. They were tasked to observe once every two weeks and report their data to Citizen Sky.
The above light curve includes all Citizen Sky data since February 1, 2011. The blue line is the 7 day mean curve based on data only from Tufts students. The red line is the 7d mean for visual observation from non-Tufts Citizen Sky participants and the green line is for photometric observations from Citizen Sky participants.Read more
