Comet Boattini in the Morning

The eastern horizon in the Southern hemisphere at around an hour and a half before sunrise (clcik to enlarge).

Comet 2007 W1 Boattini is now visible in the morning sky, at around magnitude 4.5-5. It is currently just above Rigel in Orion. Over the next few days the bright Moon may make it difficult to spot. A spotters map showing the eastern horizon an hour and a half before sunrise is here here. A more detailed map suitable for printing with the field of view of 10x50 binoculars indicated by a circle is here. Use the spotters map to locate the general area of the comet, then the detailed map to make sense of what you are seeing in binoculars.
