Today:
This evening Venus again emerges near the western horizon, but unlike last week’s conjunction with the Moon, this evening Venus joins Mercury, reaching its greatest separation from the Sun, placing it at its best for viewing. Mercury’s bright spark of light appears one hand-width to the lower left of Venus, starting near 6:20, best viewed from 6:30 to 6:40, getting lower but not setting until after 7 o’clock.
Sunday:
Daylight Saving Time begins today, as we move the clocks ahead one hour, making the sunrise and sunset an hour later. There is actually a connection to astronomy, as time used to be “local”, based on the Sun at noon. That changed in the 1800s, when trains needed a “standard” time system.
Monday:
The Scorpion is making his usual predawn appearance as winter enters its final weeks. From 2:30 to 5:30 AM EDT, this “S”-shaped constellation climbs into the southeast, with its red star Antares due south at 6:00 AM, with its head and claws to the upper right, and body and tail curling like an “S” toward the horizon.
