in 110 days 3 h
Times are local (HST).
One notification in the late afternoon, only on nights with something worth going out for over Honolulu: a very bright ISS pass, a Starlink train, a meteor shower peak, planets together, a supermoon or eclipse, the northern lights, or a bright comet. Only the city is stored, not your location.
Put Honolulu's sky in your calendar
Full moons, meteor showers, eclipses and bright ISS passes (with a 10-minute reminder) appear in your calendar and update by themselves.
Plan your night
☁️ Clouds through the night
The hour-by-hour cloud forecast appears about five days before.
🌑 Find a dark sky
City light hides most of the show. Drive until the sky looks clearly darker (often 30–60 minutes out), away from streetlights, with an open view.
🛰️ Also crossing the sky that night
Bright ISS and Starlink passes during the best hours appear about five days before.
Mars rises at sunset, stays up all night and is at its brightest of the year.
How to watch
- Look for a bright, steady star that does not twinkle.
- A small telescope shows its disk; around opposition it is at its largest.
