On Pier I at West 70th Street, the Amateur Astronomers Association points filtered solar telescopes at the sun so you can pick out sunspots and prominences curling off its edge. Volunteers at the eyepieces explain what you are seeing, so it works for curious kids and first-timers alike. If you want a free science moment folded into a riverside walk, this is the weekend's easiest one.
What to expect
You'll find a row of telescopes set up on the pier plaza, each fitted for safe solar viewing, with astronomy club volunteers taking people through them one at a time. Expect a short line at each scope, a look at sunspots and prominences, and a quick explainer before the next person steps up. Drop in whenever you like, stay a few minutes or linger by the water.
Good to know
- Take the 1, 2 or 3 to 72nd Street and walk west to the river; Pier I sits at the foot of West 70th Street in Riverside Park South.
- Views depend on a clear sky, so cloud cover can limit what the telescopes pick up; heavy rain cancels the event.
- Check nyc.gov/parks/soh about two hours ahead for weather updates.
- Never look at the sun directly or through ordinary binoculars or cameras; only use the filtered telescopes provided.
- Seating is limited and first-come, first-served, so bring sunglasses, sunscreen and water if you plan to linger on the open pier.
- Good for families and first-timers; lines at each eyepiece usually move quickly.

Common questions
Is it safe to look at the sun through these telescopes?
Yes. The Amateur Astronomers Association uses solar telescopes designed specifically for safe sun viewing. Don't try it with regular binoculars, cameras or your naked eye.
Do I need a ticket or reservation?
No. Summer on the Hudson events are free and open to the public. Seating is limited and first-come, first-served.
What happens if it's cloudy or raining?
Heavy rain cancels the session, and clouds can limit what the telescopes can see. Check nyc.gov/parks/soh about two hours before you head out.
