A spacecraft has captured bizarre magnetic “tadpoles” seemingly raining down into the Sun—an eye-catching clue about how solar magnetic fields tangle, reconnect, and move energy around the atmosphere. Worth a read if you follow space weather. #SolarPhysics #Heliophysics #SpaceWeather
The Sun Is Raining Giant Magnetic ‘Tadpoles’ - Indian Defence Review
A spacecraft just captured strange magnetic ‘tadpoles’ falling into the Sun, what they reveal changes everything.

The last ~24 hours of the Sun in EUV in 171+193+211 Å SDO AIA filters. We see the large transequatorial coronal hole now directly facing Earth. Enhanced solar wind may arrive in 2-3 days. An M1.06 flare peaking at 0756 UT on Dec 20 + non Earth-directed CME occured from AR 4315.

‼️ALERT‼️

The Administration is now targeting #NCAR, claiming it spreads federal climate alarmism.

I reject the premise that climate science is alarmist. But NCAR enables much more science research NCAR than that. Closure would be devastating, including for #heliophysics at @colorado.edu and HAO.

A large, snaking coronal hole is facing Earth. Fast solar wind from its western edge is currently affecting us now with solar wind speeds > 600 km/s. These conditions may spark active high-latitude aurora with bursts of activity reaching upper-mid latitudes at times.

A very large coronal hole is currently dominating the Earth-facing solar disk. You can see it here as this dark, snaking patch in SDO imagery. I have annotated the image. The leading edge of this coronal hole seems to be affecting Earth now, and more disturbances could be on the way.

Day 12 of #ArtAdventCalendar

Oops, I blinked and we’re almost halfway through December. Here’s a design from all the way back in 2019 that I shockingly still love. P is for Parker Solar Probe.

This screenshot is from the Planetary Science Division (PSD) meeting today, so it's fairly safe to say that this goes for all the NASA Science Divisions.
