Calendar of events for 2016

• January 3,4 – Quadrantids Meteor Shower. The Quadrantids is an above average shower, with up to 40 meteors per hour at its peak. The shower runs annually from January 1-5. It peaks this year on the night of the 2nd and morning of the 3rd. The thin crescent moon will set early in the evening leaving dark skies for what could be an excellent show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Bootes, but can appear anywhere in the sky.
• January 10 – New Moon. Occurs at 13:14 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
• January 24 – Full Moon.

• February 8 – New Moon.. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

It peaks this year on the night of May 5 and the morning of the May 6. The first quarter moon will set just after midnight leaving fairly dark skies for what should be a good show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.
• May 21 – Full Moon/Blue Moon. Occurs at 21:!5 UTC. Since this is the third of four full moons in this season, it is known as a blue moon. This rare calendar event only happens once every few years, giving rise to the term, “once in a blue moon”.

–Conjunction – position in the orbit of a planet when appears closer to the Sun as seen from Earth.
–Occultation – Moon occults or eclipses a star or a planet.
–Ascending Node – the point where a planet passes from the southern to the northern part of its orbit.
–Descending Node – the point where a planet passes from the northern to the southern side of its orbit.
