Was there a solar eclipse during the new moon?

Was the previous new moon a supermoon or micromoon?

No, there was not a new supermoon in September. The 2026 super new moons were from April to August. And there won’t be a new micro moon this year.

A supermoon is a full or new moon that nearly coincides with the closest point at which the Moon comes to Earth in its orbit, called perigee. There isn’t an official definition of the exact distance the moon needs to be to be called a supermoon. It’s approximately 360,000 kilometers or closer, depending on the definition.

The new moon must be at least 405,000 km away from the Earth to be considered a micromoon.

Was September a black moon?

No, there was not a black moon in September, or in any month this year. Recently there was a seasonal black moon in August last year as summer had an extra new moon.

There are multipe definitions of black moons. The most common, and the one you likely know, is when two new moons occur in the same month. The second new moon is typically called a black moon.

The second definition relates to having an extra new moon on the calendar during a season. When a season has four new moons, the third new moon is also called a black moon or a seasonal black moon.

The other definitions of a black moon are related to February when the month doesn’t have both a full and new moon.
