The first supermoon of 2025 is the Harvest Moon, which is traditionally the first full moon of autumn. This is when the moon is closest to the earth and, as the name implies, appears larger in the sky.

According to the Old Farmers Almanac, the Harvest Moon this year will be 224,600 miles from Earth. And, can best be viewed just after sunset.

The Draconids is unusual, in that it is best viewed in the early evening instead of early morning like most other meteor showers. 

According to “Sea and Sky,” the best viewing will be in the early evening from a dark location far away from city lights. Meteors will radiate from the constellation Draco, but can appear anywhere in the sky.

New Moon – October 21

The Moon will be located on the same side of the Earth as the Sun on this day, and will not be visible in the night sky.

This is a great time to see objects such as galaxies and star clusters with no moonlight to interfere. And it is great for the next astronomical event…

Orionids Meteor Shower – October 21-22

What a fun event to see! (“Orionid Meteor Shower is Underway” by Jeff Sullivan (www.JeffSullivanPhotography.com) is licensed under CC BY-NC-ND 2.0)

This meteor shower can produce up to 20 meteors per hour at its peak. While it occurs annually from October 2 to November 7, this year it peaks on the night of October 21 and the morning of October 22. 

Because of the New Moon, this should be a great shower to view. The best time for viewing is after midnight from a location with minimal light pollution.

Look for the planet low in the western sky just after sunset.
