After passing perihelion on July 2nd, Comet Jacques (C/2014 E2) has now moved into the early morning sky. On July 22nd it shone at magnitude +6.3, therefore just beyond naked eye visibility but bright enough to be seen with binoculars and small telescopes. The comet is now slowly decreasing in magnitude but will remain bright enough to be visible with binoculars and small scopes for many weeks to come.

Location and star chart

Jacques spends the last week of July and the first part of August moving in a northwest direction through the constellation of Auriga. It then passes into Perseus on August 5th remaining there until the 15th, before moving into the sparse dim constellation of Camelopardalis. During this time, it's expected Jacques will fade in brightness from magnitude +6.3 to +7.0. For Northern Hemisphere observers, the comet is now well placed for observation. It's visible towards the east in the morning sky, improving in latitude as the month progress. From Southern Hemisphere latitudes Jacques is visible very low towards the eastern sky during morning twilight at the end of July, but is then quickly lost to the bright glare of the Sun and won't be visible again until early September.
