AND... WE HAVE LIFTOFF of NOAA’s #SWFOL1 satellite, riding along with NASA.gov's Interstellar Mapping and Acceleration Probe (#IMAP) and Carruthers Geocorona Observatory! More about SWFO-L1: noaa.gov/SWFOL1 #LetsGoSWFO!

Grab your coffee and tune into the #SWFOL1 launch livestream in progress from NASA's Kennedy Space Center! Launch time scheduled for 7:30 a.m. EDT today, 9/24. *** See the livestream NOW at: noaa.gov/SWFOL1 and on the NOAA Satellites Facebook page at www.facebook.com/NOAASatellit...

SWFO-L1 🚀LAUNCH UPDATE per NASA Kennedy: NASA and SpaceX are now targeting 7:30 a.m. EDT, Wed Sept. 24 for the launch of IMAP, SWFO-L1, and Carruthers to allow more time for recovery assets to arrive at the landing zone. All 3 spacecraft and rocket remain healthy. science.nasa.gov/blogs/imap/2...

The Fall/Autumnal Equinox is TODAY at 2:19 PM EDT. That's the time at which our Sun is directly over the Earth's equator, signaling the start of Northern Hemisphere astronomical fall. The Earth’s northern hemisphere will continue to tilt further from the sun through the Winter Solstice on Dec 21.

We're at T-minus 4 days & counting until the SWFOL1 launch! 🚀 NOAA's #SWFOL1 🛰️ will improve #SpaceWeather forecasting: Its magnetometer will track solar plasma heading toward Earth and help forecast geomagnetic storms. More: noaa.gov/SWFOL1 #SWFOMission #LetsGoSWFO #CountdownToLaunch

Though temperatures will feel very beach-like, increasing northeast winds this weekend will bring a high rip current risk to local beaches in parts of Florida and Georgia. Locals and visitors, should follow beach patrol guidance & flags. Visit weather.gov/beach for the latest forecast info.
