Abstract

A total of 100 V-band photometric observations were made at Holtsville Observatory for the 2009–2011 eclipse of e Aurigae. A light curve has been plotted using data from these observations which covers the phases before, during, and after the eclipse. The light curve shows precise timing during the first, second, third, and fourth contacts, which mark important parts of the eclipse. The magnitudes and duration of the eclipse in the photometric V band are discussed.
