Comet Lemmon (C/2012 F6a), and Comet PanSTARRS (C/2011 L4) are
sweeping through southern skies. Lemmon's lime green coma and
thin tail are near the left edge of this telephoto scene, a
single frame from a timelapse video (vimeo here) recorded on
February 12, tracking its motion against the background stars.
Comet Lemmon's path brought it close to the line-of-sight to
prominent southern sky treasures the Small Magellanic Cloud and
globular cluster 47 Tucanae (right). Sporting a broader, whitish
tail, Comet in later video frames moving through the faint
constellation Microscopium. Visible in binoculars and small
telescopes, both comets are getting brighter and headed toward
northern skies in coming months.
