Comets Lemmon and PanSTARRS ᐉ
Two comets -C/2012 F6 (Lemmon) and C/2011 L4 (PanSTARRS)- can be seen moving through the southern sky in this timelapse video (music added) made of several sequences during February 2013 as the comets were becoming brighter while approaching the sun. All scenes are made from southeastern shore of Australia in Victoria. The two comets show diverse cometary tails. In view comet Lemmon (C/2012 F6) appears near the Small Magellanic Cloud (a Milky Way’s dwarf satellite galaxy). The green cast on the wide-angle view is an active airglow (faint natural emission of the Earth upper atmosphere). Red dancing lights appear across the southern horizon at time 00:28s which is a sudden burst of Aurora Australis. The next scene is a close up telephoto view of comet Lemmon passing against the Small Magellanic Cloud (our neighboring satellite galaxy). The Lemmon’s lime green coma and thin tail are visible along with a southern sky treasure the impressive globular cluster 47 Tucanae. Starting at time 00:50s the video shows comet PanStarrs with its growing fan-shaped tail.
