A total of 100 V-band photometric observations were made at Holtsville Observatory for the 2009–2011 eclipse of epsilon Aurigae. A lightcurve has been plotted using data from these observations that which covers the phases before, during and after the eclipse. The lightcurve 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.
