Comet C/2012 S1 (ISON) - November 15, 2013

Comet C/2012 S1 (ISON) was still rising early enough to clear the trees (approximately 7-degrees altitude) at the Clubhouse before astronomical twilight. Looking E-SE, I still had to contend with local light pollution on the horizon as well as partly cloudy conditions that morning. The comet was still a binocular object under the local sky at the Clubhouse.
