What is happening today
Whether a solar eclipse occurs on a given day depends on the Moon’s precise alignment with the Sun and Earth. Eclipses do not happen every month because the Moon’s orbit is tilted, so their paths across Earth are narrow and predictable. If today falls within an eclipse season—roughly every six months—there may be a solar eclipse, partial, annular, or total, depending on the Moon’s distance and location. Use authoritative eclipse calendars from NASA or timeanddate.com to confirm if the Sun’s disk will be partly or fully obscured in your area and to see start, maximum, and end times for your city.
Visibility map and path details
Solar eclipses are visible only along a narrow track. For a total eclipse, this path of totality might be 100–200 kilometers wide, crossing states or regions for a few minutes at most. Nearby locations see a partial eclipse, where the Moon covers part of the Sun. Online interactive maps show the eclipse magnitude (fraction of the Sun obscured), altitude, and azimuth over time. Typical parameters include the eclipse magnitude at maximum and the Sun’s coordinates at greatest eclipse.
Key path metrics
| Parameter | Definition | Example range |
|---|---|---|
| Eclipse magnitude | Fraction of the Sun’s diameter covered | 0.0–1.0+ (partial to total) |
| Path of totality width | Surface width where total eclipse is visible | ≈100–200 km |
| Duration of totality | Seconds the total phase lasts at a given point | ≈1–8 minutes |
How to watch safely (do not look directly)
Viewing a solar eclipse without protection can cause permanent eye damage. The only safe way to look directly at the uneclipsed or partially eclipsed Sun is with ISO 12312-2 eclipse glasses or handheld solar viewers that meet international safety standards. Regular sunglasses, smoked glass, or unfiltered cameras and telescopes are not safe. If you do not have certified viewers, project the Sun’s image onto a surface using a pinhole or a telescope with a proper solar filter. During totality, when the Moon completely covers the Sun’s bright disk and the solar corona becomes visible, you may remove filters, but immediately replace them as soon as the Sun begins to reappear.
Phases and timing explained
A solar eclipse progresses through identifiable stages. Contact times are usually given in local time for first contact (partial begin), second contact (totality or annularity begin), third contact (totality or annularity end), and fourth contact (partial end). Between second and third contact, the eclipse is total or annular, depending on the Moon’s apparent size. Eclipses are predictable centuries in advance because orbital mechanics are well understood, though small timing differences appear based on your horizon and elevation.
Weather, location, and planning tips
Clouds are the most common reason an eclipse cannot be seen, so check short-term forecasts and consider traveling within the path if your weather is poor. Higher elevation or coastal sites sometimes have clearer views, but local terrain matters more than general climate. If traveling, account for traffic and accommodation needs; large crowds can occur for notable eclipses. For future eclipses, note that paths shift because the geometry of Earth, Moon, and Sun changes. Reliable sources for planning include NASA’s eclipse website and national observatories that publish regional event details.
Myths versus facts
Misinformation circulates around eclipses, including ideas that they are uniquely dangerous or that special rituals are required. Scientifically, an eclipse is a predictable alignment that can be observed safely with proper eye protection. No astronomical eclipse poses a risk to your location beyond the temporary need for caution during partial phases. Historical eclipse records are useful for science, but they do not imply supernatural causes; modern orbital calculations explain them precisely.
Equipment and observation checklist
- Certified ISO 12312-2 eclipse glasses or approved solar viewer
- Pinhole projector or telescope with solar filter for indirect viewing
- Weather forecast check and backup travel plan
- Charges devices, arrive early if traveling, and avoid looking at the uneclipsed Sun
