Jupiter & Comet 46P/Wirtanen

Magnificent Jupiter rises at dawn in the southern sky every morning this month followed by Mercury and Venus. Use binoculars to spot Jupiter's 4 biggest satellites: Ganymede, Callisto, Io & Europa. You can find Jupiter in Sagittarius.


Comet Wirtanen will pass several deep-sky objects in constellation Auriga and glowing around 9th magnitud. On March 23 will be the next time the comet could be observed without the moon in sight. You may need binoculars to watch it. Auriga is in the western horizon at night, around 9pm this month.
