Solar eclipseLocally visible
Partial solar eclipse
60% of the solar disk covered at local maximum. Sun 46.9° high. Local contacts assume an unobstructed horizon. Proper solar protection is essential.

Solar eclipse visibility is not observing permission. The Sun needs appropriate front-aperture solar filtration. Event geometry does not account for clouds, and local obstacles can block the view. Solar safety guidance
Meteor shower seasons
Approximate recurring peak dates, not year-specific outburst predictions. Radiant altitude and moonlight are calculated for 03:00 local time on the date shown. Look with your eyes, not a telescope.
Annual season references: NASA and American Meteor Society. Verify the annual calendar before travel.
Live comet/asteroid alerts, retrograde stations, meteor outbursts and organised dark-sky event dates are not connected. New Moon dates are included to help you plan dark-sky nights.
