The Delta Aquariids peak July 30, but a full moon will drown them this year

Two meteor showers reach their peak on the night of July 30: the Southern Delta Aquariids and the Alpha Capricornids. In a good year that’s a fine reason to drive up to Troodos and lie back for a couple of hours. This is not a good year.

The plan, then: don’t waste a special trip on July 30.

It also happens to sit near apogee — 406,135 km from Earth — making it a Micromoon: roughly 5.5% smaller in angular diameter and about 10% dimmer than an average full moon. It’s the most distant full moon of 2026. And if you walk outside that night expecting something visibly unusual, you’ll be disappointed. ...
