A Black Moon. How It Differs From Last Year’s Supermoons

Tomorrow’s moon will be the second supermoon of 2015. The first was on January 20th and tomorrow’s is a lot like it. It’s a new moon. It’s also known as a seasonal Black Moon, the third of four new moons during the current season.

While it sounds cool, you won’t be seeing anything. Unlike a full moon supermoon, which is out all night, a new supermoon can only be seen during the daytime. The sun’s bright glare makes that impossible.

You might be wondering how tomorrow’s moon qualifies as a supermoon. The definition of a super moon covers a full moon or new moon as it reaches the closest point to Earth. Tomorrow’s new moon is expected to reach this point, known as lunar perigee, shortly after the moon turns new.

Supermoons do affect the tides a bit more than traditional full and new moons. Tomorrow’s tides will be called a perigean spring tide. It does rise more than a traditional tide, but usually doesn’t cause flooding. If you are living in a coastal flooding prone area and have a strong weather system around – keep an eye out. Strong storms can pile-on to the effect of a perigean spring tide.

March’s Supermoon Will be Special for Some

On March 20th, another supermoon will happen. This one will also be a new moon. What makes this one special is what people in far-northern Arctic latitudes will see. A total solar eclipse as the new moon passes right in front of the sun. A partial solar eclipse will be seen for many living throughout Europe, northern Africa and northeastern Asia.

The full moon supermoons will happen during a three month period starting in August. The first will be on August 29th. Two more will occur on September 29th and October 27th.
