ANOTHER CME IS COMING: On March 13th, an unstable filament of magnetism in the sun's far-southern hemisphere exploded. The resulting CME could deliver a glancing blow to Earth's magnetic field on March 17th. Minor G1-class geomagnetic storms are possible if/when the CME arrives. Aurora alerts: SMS Text.
ACTIVE SUNSPOT: It is 200,000 km long and crackling with M-class solar flares. We're talking about sunspot AR2965. This morning in Malaysia, Karzaman Ahmad photographed the sprawling active region from the Langkawi National Observatory:
AR2965 has an unstable 'beta-gamma' magnetic field. Between the sunspot's many dark cores, patches of north and south magnetic polarity are pressed together, creating conditions ripe for explosive magnetic reconnection. As a result, we have seen M-class solar flares 3 out of the past 5 days.
So far, the explosions have not hurled any significant CMEs toward Earth. Their primary effect has been to cause a series of minor shortwave radio blackouts. Mariners, aviators, and ham radio operators may have noticed unusual propagation at frequencies below 20 MHz. Solar flare alerts: SMS Text. ;

STERLING SILVER FROLICKING DOLPHIN: On Feb. 28, 2022, the students of Earth to Sky Calculus launched a cosmic ray research balloon. This sterling silver dolphin hitched a ride, flying 111,101 feet above the Sierra Nevada mountains of Central California:
You can have it for $142.95. Leaping through blue crystal waves, the playful cetacean is 100% 925 sterling silver. It comes with a matching 18-inch sterling silver chain The entire pendant is lead-free, nickel-free, cadmium-free, and totally hypoallergenic.
Each pendant comes with a greeting card showing the dolphin in flight, and telling the story of its trip to the edge of space and back again. All sales support the student's cosmic ray research program.
