RT @eumetsat: We're now officially in autumn 🍂
Saturday 23 September marked the #AutumnEquinox in the Northern Hemisphere - when the Sun hits the Earth's equator - resulting in equal sunlight/darkness across the planet 🌗
This image was taken by our #Meteosat satellite at 09:00 UTC 🛰️

RT @JPSSProgram: This animation shows changes in vegetation across various regions in the Northern Hemisphere, including North America, captured by NOAA’s JPSS satellites from April to mid-September 2024.

See how the greenery subtly shifts as we approach the #AutumnEquinox. 🔎🌳 https://t.co/IUSHqrKErZ

Happy #AutumnEquinox! Yesterday marked the astronomical start to autumn in the Northern Hemisphere.
That means shorter days & longer nights - we're looking forward to those autumn colours! 🍁🍂

Yesterday marked the #AutumnEquinox, signaling the official start of astronomical #fall in the Northern Hemisphere!

Over the past year, we've gathered a daily image from @NOAA's #GOESEast 🛰️, taken at the same time each day. Together, they show the sun's angle shift over time due to the Earth's tilt, resulting in the changing seasons.

Astronomical #fall began across the Northern Hemisphere yesterday! Check out this time lapse of daily images from @NOAA's #GOES16 🛰️ that shows how dramatically the sun's angle changed from last #AutumnEquinox to this year's. https://t.co/YLKyxyP0cj

On this first day of the #AutumnEquinox, the Compact Coronagraph-1 (#CCOR1) onboard @NOAA's #GOESEast 🛰️ captured both the moon and Earth while watching the sun.

@NOAA’s upcoming #SWFOL1 observatory will also carry a compact coronagraph called #CCOR2.

🍂 It's the first full day of #autumn after the #AutumnEquinox, and @NOAA’s #GOESEast 🛰️ has been tracking the sun’s changing angle over the course of the past year due to Earth's 23.5° tilt. 🌎
