Comet ISON Parting Shot

Comet ISON (C/2012 S1) appears in the morning twilight, on its way to the Sun, only 4 days before reaching within a solar diameter of the Sun’s surface (on 2013 Nov. 28). This was the last morning that the TWAN photographer managed to capture a clear view of the comet before it sinks to the solar glare. This unusual sungrazer comet is captured here with a telephoto lens as it is rising over Gran Canaria Island, photographed from the Teide Observatory on Tenerife.
