Quadrantids Meteor Shower

Period of activity: December 27th, 2019 to January 10th, 2020. 

Peak: Jan 3-4, 2020 – the moon will be 4% full.

The Quadrantids have the potential to be the strongest shower of the year but usually fall short due to the short length of maximum activity (6 hours) and the poor weather experienced during early January. The average hourly rates one can expect under dark skies is 25. These meteors usually lack persistent trains but often produce bright fireballs. Due to the high northerly declination (celestial latitude) these meteors are not well seen from the southern hemisphere.

Shower details – Radiant: 15:18 +49.5° – ZHR: 120 – Velocity: 26 miles/sec (medium – 42.2km/sec) – Parent Object: 2003 EH (Asteroid)

New Moon

By the modern definition, New Moon occurs when the Moon and Sun are at the same geocentric ecliptic longitude. The part of the Moon facing us is completely in shadow then. Pictured here is the traditional New Moon, the earliest visible waxing crescent, which signals the start of a new month in many lunar and lunisolar calendars.
