A CME from the sun is headed our way. A low level geomagnetic storm – with auroras at high latitudes – is possible. NASA estimates the CME will impact Earth late on March 27, 2022, or early on March 28. Activity at Earth is expected to be minor.
The upcoming CME is from a March 25 solar flare, which also caused a shortwave radio blackout over southeast Asia.
March 26: A solar tsunami
On Friday morning, March 25, 2022, sunspot AR2974 in the sun’s southern hemisphere produced an M-class flare. The explosion also sent a solar tsunami – officially called an EIT wave – rippling through the sun’s atmosphere. See the animation below.
March 25: A large and active sunspot group rotates into view
A new sunspot group, or active region, has rotated into view on the Earth-facing side of the sun. The central part of the sunspots is at least as large as two Earths! The region, labeled AR2975, had produced multiple C-class flares over several days.
A large coronal hole near the sun’s center is now in range to send some activity toward Earth in the form of high-speed solar winds. When the stream reaches us in another couple of days, scientists anticipate elevated geomagnetic activity. This means a good chance for auroras.
To our readers and community
We invite you all to send us your beautiful recent photos of sunspots and auroras! We love receiving your photos. To those of you who’ve already posted a photo to our community, thank you!
Something just exploded on the far side of the sun. On March 21, the Solar and Heliospheric Observatory (SOHO) recorded a massive CME emerging from behind the sun’s southwestern limb.
A few hours later, it happened again. If Earth had been in the line of fire, we would now be anticipating a strong geomagnetic storm. Instead, the storm clouds will miss our planet.
March 21-22: Prominence on sun’s limb
PROMINENCE ERUPTION (AS FORECAST): A prominence on the NE limb of the Sun erupted. To get an idea of the massive scale of these eruptions I have included a image of the Earth to scale. Note the flows along the magnetic loops. This is too far east to significantly affect the Earth pic.twitter.com/CQVpZwpbrt
C. Alex Young is a solar astrophysicist studying the Sun and space weather. Alex is passionate about sharing science with diverse audiences. This led him to start The Sun Today with his designer wife, Linda. First through Facebook and Twitter then adding an extensive website thesuntoday.org, the two work together to engage the public about the Sun and its role in our solar system. Alex led national engagement efforts for the 2017 total solar eclipse. He is the Associate Director for Science in the Heliophysics Science Division at NASA Goddard Space Flight Center.
Armando is well known as an astronomy educator, after 30+ years leading extensive initiatives of public outreach and 10+ years teaching in colleges. As one of only a handful of Puerto Rican science communicators during Comet Halley's last visit, he assumed a pioneering role starting in 1985 when science was just beginning to enter the local mindset; over time his work brought meaningful change to the culture, inspiring people to pursue interests in science and technology. His affiliations include Ana G. Méndez University–Cupey, where in 2014 he spearheaded an 8-course extension program focusing on observational astronomy, the first ever in the island.
Raúl Cortés studied engineering at the Autonomous University of Nuevo León in Monterrey, Mexico, obtained a scholarship to continue his studies in Japan and after returning to Monterrey he got credits on MBA from the Graduate School of Mechanical and Electrical Engineering Faculty. He became a teacher at the University UANL teaching Math and Physics and dedicated the rest of his professional career to serve in engineering areas for USA, Japan and Germany based corporations. His passion for the skies go back to when he was a child, always intrigued about the stars and constellations and reading and researching about the matter. From 2010 on, he dedicated his attention to photographing the stars, constellations, the moon and the sun. Raúl's work on his photography has been published and posted on the ESC as well as in other platforms and has gained attention to be published by local Monterrey newspapers.
