Timings for the eclipse contact points and mid-eclipse, length of ingress and egress, average magnitude during eclipse, and timings for out-of-eclipse variations have been determined in the V band for the long period eclipsing binary epsilon Aurigae during the 2009–2011 eclipse. This has been done with data from the International epsilon Aurigae Campaign 2009 and AAVSO. Comparison with data from previous eclipses has also been made.
