The summer solstice is the day with the longest period of daylight and the shortest night of the year in a given hemisphere, and marks the beginning of astronomical summer. In the Northern Hemisphere, it typically falls on June 20 or 21. <\/p>\n\n\n\n<p>GOES satellite imagery provides a unique view of the earth as we pass through the various seasons. The angle of the shadow at sunrise or sunset (satellite time, or at the satellite nadir point) shows how earth progresses through the seasons from summer solstice to fall equinox. Watch the reflection of the sun migrate through the imagery, in this case from the southern hemisphere to the northern hemisphere in this animation of GOES-East from the winter solstice (Dec 21, 2024) to the summer solstice (Jun 20, 2025).<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1048\" style=\"aspect-ratio: 1024 \/ 1048;\" width=\"1024\" controls src=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2025\/06\/GOES19_CIMSSNatColor_Winter2SummerSolstice2025_Sunset.mp4\"><\/video><figcaption class=\"wp-element-caption\">GOES-East (GOES-16 through Apr 7 and GOES-19 after) Full Disk \u201cCIMSS Natural Color\u201d animation from Dec 21, 2024 to June 20, 2025 at local sunset (23:00 UTC).
