Catch Comet Jacques Near Venus At Dawn

Venus will help us find Comet Jacques in Taurus an hour and a half before sunrise tomorrow morning July 16, 2014. The comet will be near the naked eye star Beta Tauri during the next week. Source: Stellarium

I don’t take getting up at dawn in summer lightly. After all, it means you’ve got to set the alarm for the ungodly hour of 4 a.m. (even earlier if you live in the northern U.S. or southern Canada.) But I wanted to alert you to the return of Comet C/2014 E2 Jacques.

Jacques disappeared in evening twilight a month ago, passed closest to the sun on July 2 and has recently returned to view low in the northeastern sky at dawn. Still stoked from its solar encounter, the comet shines at magnitude +6, the naked eye limit.

Don’t expect to see it yet without optical aid however. Jacques flirts with morning twilight and only climbs to around 10° (one fist held at arm’s length) the next couple mornings. Low haze and dust will make it look fainter, but not so much that a pair of 50mm binoculars might catch it.

We’re fortunate to have Venus and the star Beta Tauri to help guide us to the comet. The critical requirement for seeing Jacques, whether it be in binoculars or more likely in a small telescope, is an open view of the northeastern sky.

Timing is also important. In the northern U.S., the comet will be a little higher in the sky but observers will have to compete with earlier and longer twilights. The southern U.S. has the edge for the moment with the comet a little better placed in a darker sky.

Views will improve for everyone over the next few weeks as Jacques pulls away from the sun, buoyed along by the seasonal drift of the stars and its own westward motion.

Indications are that the comet will remain near the naked eye limit through early August, so we may really get a chance to see it without optical aid from rural skies. In any case, binoculars should reveal it as a small fuzzball rolling across Auriga and Perseus.

By mid-August, Jacques will fade but remain visible in the evening sky through the remainder of the year. I hope you become fast friends with this blurry blob soon!

* UPDATE July 16, 2014 – Checked the comet this morning and although there were a few clouds, I wasn’t able to see it in 10×50 binoculars. Too much twilight here in the northern U.S. ! But the view in the telescope was excellent. Jacques was an obvious fuzzy glow with a bright center a couple degrees below Beta Tauri even in dawn light. I estimated magnitude 6.
