Southern Delta Aquariids in Helsinki

The Southern Delta Aquariids meteor shower peaks from Helsinki around Jul 29-30, with up to 25 meteors per hour under ideal conditions. In 2026 a bright moon will hide most meteors except the brightest, and from Helsinki the radiant in Aquarius climbs to 13° above the south horizon around 03:25. Local best viewing window: 01:05–03:50 EEST on the peak night, about 2.8 hours of civil twilight. Scaled to that altitude, the 25/hour headline figure works out to roughly 6 meteors an hour from Helsinki under a genuinely dark sky. At this latitude the sky never gets fully dark that night — the Sun only reaches 11.3° below the horizon — so only the brighter meteors will show. Tonight: unbroken cloud; conditions are as poor as they get.
