- It occurs several times a year.

Some people think that it was a super-blood moon that was seen, but since total lunar eclipses are rare, you get to see super-blood moons at intervals of about ten years, he says.

Super blood moon even redder

The next time a superblood moon can be seen is in 2028, according to Hans Thorgren, who has a master's degree in astrophysics and has written textbooks on the subject.

- Now it was partly red, but not as red as when it is super blood moon, he says.

How common is it that the supermoon is seen several evenings and nights in a row?

- It stays for a few days, but exactly how many minutes it stays each time depends on where in the orbit the moon is and the earth is so I can not answer exactly, but it varies, says Hans Thorgren.  

Ten years apart

According to Thorgren, the next time the supermoon appears will be in August 2023.
