The light in the sky
Last week I spotted a brilliant object in the sky. At first I thought it was Venus but Venus rises at dawn, not at 7 something pm. Jupiter rises after midnight these days, so it wasn't Jupiter either. The brighter stars in the vecinity were Sirius and Canopus, higher in the sky at that moment--so what the hell was that? I still don't know. I went for my binoculars and I noticed the thing was double and it was just fixed in the sky. Later it started to rain and I didn't see it again--actually I haven't seen it again.

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.
