The Winter Triangles?

The Summer Triangle is the famous asterism formed by the stars Vega, Deneb and Altair. And while we enjoy it’s sights high overhead on warm summer nights, this time of year we have a double chance to take a look. Thanks to the long winter nights, the Summer Triangle is visible low in the west just after sunset. It’s also visible low in the east just before sunrise. So you can pick your time and enjoy some summer sights in the middle of winter.

Then, for the time in between, there’s the asterism that really is known as the Winter Triangle.  It’s corners are the bright stars Betelgeuse, Sirius and Procyon.  This triangle is visible in the southern sky all through these winter nights.
