If you look out your window tonight, you can observe an event that is happening for the first time in more than 30 years. The last supermoon eclipse was in 1982. Supermoons happen once a year. It means the moon appears 14% larger and 30% brighter. However, the combination of the eclipse and supermoon is a rarity. It won’t happen again until 2033.
The orbit of the moon is not a perfect circle. At times it’s closer to the earth than at other times. Tonight’s supermoon is the closest full moon of this year. Here in the San Francisco East Bay Area, it’s a cloudless, fogless night and the moon is in plain view.
Take a look, it might be a useful addition to a setting for a story.
