While we can’t predict what nights the auroras will be out in any given month, we can predict which nights are more likely to be extra dark.
What do we mean by “extra dark”?
We mean a new moon. During the new moon phase, the sky is extra dark, increasing the number of stars seen, and a less powerful solar storm is more likely to be seen.
Our new moons of the 2025 summer season will be at these times:
- May 16
- June 14
- July 14
- August 12
- September 10
- October 10
Attempts to catch a glimpse of the fabled aurora borealis during a new moon are often much more successful than during any other moon phase.
Remember, the couple days before and after a new moon are usually nearly as dark as the new moon.
