GEOMAGNETIC STORM WATCH (G1): NOAA forecasters say that minor G1-class geomanetic storms are possible on July 12th when a CME might graze Earth's magnetic field. NASA models suggest a more direct hit, but G1 is probably still the correct forecast for this lightweight CME. CME Impact Alerts: SMS Text
LUNA AND THE SEVEN SISTERS: Gwenael Blanck sends this report from Paris: "This morning, a thin crescent Moon appeared right next to the Pléiades star cluster. I captured the duo directly above the Eiffel tower."
"The Pléiades were not visible to the naked eye," says Blanck, "but the encounter was truly beautiful through binoculars, especially with the Earthshine!"
In Sweden, the Moon passed directly in front of the Pléiades, producing a lovely occultation. And, in Italy, they appeared directly above the famous Cyclopean Isles. Browse our realtime photo gallery for even more views of Luna and the Seven Sisters.

THE 18K GOLD 'METEOR CRATER' PENDANT: Have you heard of Moissanite? It's a very rare mineral discovered by 19th-century chemist Henri Moissan in Arizona's Meteor Crater. At first, he thought it was diamond, but later realized it was even more rare. It's a diamond mimic that, until the 1950s, was found naturally only in meteorites.
On May. 29, 2025, the students of Earth to Sky Calculus launched this Moissanite pendant to the stratosphere onboard a cosmic ray research balloon:
You can have it for $199.95. Engraved with the words "I love you always and forever", this 18K gold-plated sterling silver pendant has a heart-shaped ruby crystal in the middle surrounded by a heart-shaped ring of glittering 5A cubic zirconia nuggets..
The students are selling space pendants to pay the helium bill for their cosmic ray ballooning program. Each one comes with a greeting card showing the jewelry in flight and telling the story of its trip to the stratosphere and back again.
