The September 2025 solar eclipse will be a major celestial event for viewers across the United States, offering a rare chance to witness the Moon sliding in front of the Sun. This guide outlines the key timing details, regional differences, and practical planning tips for observers in the USA.
Because the path of annularity crosses multiple states, many people will need exact local timings to plan travel and photography. The following sections break down what to expect and how to prepare safely.
| Phase | Start (Local) | Peak | End (Local) |
|---|---|---|---|
| Preliminary Contact | 10:06 a.m. PDT | Annularity at 3:56 p.m. PDT | 5:10 p.m. PDT |
| First Bite (Partial Start) | 10:48 a.m. PDT | 5:05 p.m. PDT | |
| Annularity Begins | 3:47 p.m. PDT | 4:05 p.m. PDT | |
| Maximum Eclipse | 3:56 p.m. PDT | 4:01 p.m. PDT |
Path of Annularity Across the USA
States and Cities in the Ring of Fire
The path of annularity on September 2025 passes through portions of Oregon, Nevada, Utah, Arizona, New Mexico, and Texas, with cities such as Reno, Phoenix, and El Paso experiencing the “ring of fire.” Outside this narrow corridor, viewers will see a partial eclipse.
Timing Variations by Location
Exact start and end times shift by several minutes depending on your position within a state, so always check a local forecast using official sources. Coastal viewers may see slightly different timing than inland locations because of horizon geometry and elevation.
Safety and Viewing Requirements
Protective Equipment and Techniques
During annularity, when the Sun appears as a bright ring, you still need certified eclipse glasses or hand-held solar viewers that meet ISO 12312-2. Regular sunglasses, even very dark ones, are not safe for direct Sun viewing at any stage of the eclipse.
Planning for Weather and Crowds
Popular locations along the path can fill quickly, so book accommodations and permits early if required. Cloud cover is common in September across the Southwest, so have a backup site or consider live streams from reliable observatories if local conditions are poor.
Photographic and Observational Tips
Camera Settings and Equipment Prep
Use a solar filter over your lens or telescope at all times except during the brief period of annularity, and test your setup before the event. For smartphones, attach a certified solar filter and avoid digital zoom to keep images sharp and safe.
Timing Your Observations
Set multiple alarms based on the precise times for your exact location, and start setup at least 30 minutes before first contact. Practice framing your shot using the partial phases, then switch to video or burst mode during annularity to capture the ring and surrounding corona.
Resources and Regional Planning
- Check official NASA and NOAA eclipse maps for precise local timings in your city.
- Book travel and lodging early if you are within or near the path of annularity.
- Verify that your eclipse glasses have the ISO 12312-2 certification mark.
- Practice photography settings during the partial phases to reduce stress on eclipse day.
- Monitor weather forecasts in the week leading up to September 2025 and prepare contingency plans.
FAQ
Reader questions
Will I need special glasses if I am outside the path of annularity?
Yes, you still need ISO-certified eclipse glasses for any partial phases, even if you are outside the path of annularity, because the Sun will never be completely covered.
Can I use my camera or phone without a solar filter?
No, never point an unfiltered camera or phone at the Sun, even during partial eclipse phases. Use a proper solar filter or project an image to protect your equipment and your eyes.
How accurate are the eclipse times listed in official apps?
Official apps and websites provide times accurate to within a few seconds for specific locations, but always double-check using a trusted observatory or government source close to the event date.
What if bad weather blocks the view on September 2025?
Consider watching a live stream from a trusted observatory or science museum, and keep an eye on extended forecasts, as clear skies can appear in nearby regions just before or after your local time.
