How to spot NOAA-20 from Philadelphia
NOAA polar weather satellite (JPSS).
- Look in the direction listed — passes start near the horizon and arc across the sky.
- Peak elevation matters — a 60°+ peak means it'll go nearly overhead; under 30° stays low.
- Best viewing is in the 90 minutes after sunset or before sunrise — the satellite is sunlit while you're in shadow.
- No equipment needed for bright passes — the ISS at peak rivals Venus.
Going to look up?
For fainter satellites you'll want 7×50 or 10×50 binoculars. A pair of Celestron SkyMaster binoculars is the consensus pick. Affiliate placement — replace with your affiliate link.
