Today:
As twilight fades from 9:00 to 9:30 PM, can you make out the letter “W” formed by five medium-bright stars, low above the northern horizon? This forms part of the throne of Cassiopeia, the Queen. To her upper right, still low, you might see a house-shaped pattern – a box with a triangle on top. This is the Queen’s husband, King Cepheus.
