Comet C/2012 F6 Lemmon cruises up the side of the familiar Great Square of Pegasus this month. Look for it starting about 90 minutes before sunrise low in the eastern sky. Let the W of Cassiopeia point you toward Alpha Andromedae; from there you can star-hop to the comet using binoculars. Stellarium
Looks like Comet PANSTARRS has company.This week Comet Lemmon begins nudging its way into the early dawn sky. Watch it to slowly climb up the eastern side of the Great Square of Pegasus in the coming weeks. Both comets are now below the naked eye limit and glow around 7th magnitude.
A beautiful pairing of Comet PANSTARRS and two bright nebulae – NGC 7822 (top) and Cederblad 214 (center) – in the constellation Cepheus on April 30. The colors of the comet and nebula are strikingly different. Sunlight reflected by dust colors the comet’s tail yellow; the light of hot, young stars embedded within the nebulae causes hydrogen gas to fluoresce red. Credit: Michael Jaeger
From a dark sky 7×50 and 10×50 binoculars will easily show Lemmon as a fuzzy spot, and you might even spot a long, thin tail. The comet slowly fades during the month while rising higher and becoming easier to see in the morning sky. You can use the map here to help guide you to it; for more details, check out this recent article I wrote that appeared in Universe Today.
