MINOR CME IMPACT POSSIBLE TODAY: Minor geomagnetic storms are possible today when a CME<https://spaceweather.com/images2023/06mar23/cme_anim.gif> might sideswipe Earth's magnetic field. The CME was launched from the sun on March 6th, the aftermath of an M5.8-class solar flare<https://spaceweather.com/images2023/06mar23/m6_teal_anim2.gif>. It wasn't well aimed. Only a weak glancing blow is expected, but even weak CME impacts can spark Arctic auroras. Aurora alerts: SMS Text<https://spaceweatheralerts.com/>.

THE WORM MOON IN TWO HEMISPHERES: According to folklore, last night's full Moon was the Worm Moon, heralding the arrival of northern spring and the stirring of earthworms in thawing soil. Amateur astronomers Lucy Yunxi Hu and Soumyadeep Mukherjee photographed it from both hemispheres:

"We've been working on this project for 6 months," says Mukherjee, "and we were finally able to make it happen after overcoming a lot of challenges."

Operating their cameras thousands of miles apart, Mukherjee and Hu photographed the moonrise on March 7, 2023, from Dhanbad, India (top) and Canberra, Australia (bottom). The Worm Moon ascended the sky in different directions because Earth's eastern horizon at these two locations has a different angle relative to Earth's spin axis. "Nevertheless," says Mukherjee, "it's only one Moon!"

Cosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining--a result of the yin-yang relationship between the solar cycle and cosmic rays.
