Aurora and Approaching Comet

By: Alex Cherney


Region: Australia and Pacific

Site: Victoria - Australia

Date: 2013 February 17

This timely image from the southeastern shore of Australia in Victoria has captured a sudden red burst of aurora australis, the green cast of airglow (natural emission of the Earth upper atmosphere), our neighboring satellite the Small Magellanic Cloud, and comet Lemmon Lemmon (C/2012 F6) while approaching the sun. Find the comet with its faint thin tail and the green coma at the upper middle of the image. See this scene in a timelapse video. Alex Cherney,
