Annular solar eclipse, dense ground fog is a sign of fall

Make Sure To Catch The Annular Solar Eclipse On October 14. No, annular does not mean “yearly;” it’s taken from the Latin word anulus, meaning “little ring.” In geometry, the annulus is the space between two concentric circles. If you are in the direct path of a solar annularity, you will see the moon pass in front of the sun, leaving a ring of sunlight around the shadow of the moon. That path runs from Oregon to Texas; here in San Diego, we will see a partial, crescent eclipse that will peak at 9:26 am. It will look similar to a crescent moon but instead, it will be the sun. While the eclipse is occurring, make sure to look around at objects near you; the partial sunlight will give things a surreal, yellowish, high-contrast appearance. As for the eclipse itself, be sure to look at it only though a filter or eclipse glasses. Never look directly at the sun. Check out the watching party at the Fleet Science Center.

If You Miss This Eclipse, Mark Your Calendar and make sure not to miss the April 8, 2024 total solar eclipse. We won’t see another until 2045.

Dense Ground Fogs Are A Trademark Of The Onset Of Autumn along San Diego’s coastal strip. Fog materializes during the night and early morning hours when moist marine air that has settled in valleys and low areas is chilled below the dew point. These ground fogs are distinct from the low overcast that usually blankets the coastal strip on late-spring and summer mornings.
