INCREASING CHANCE OF FLARES: Sunspots are growing again, especially in the sun's northern hemisphere. Nine different sunspot groups are currently facing Earth. New sunspot AR4142 has a delta-class magnetic field that harbors energy for X-class solar flares.

LOL, pity the poor clowns clinging to the myth of a GSM now. Two or three posted that “sun spot numbers declining catastrophically show the GSM is here!” 146 spots today, not that the 83 of yesterday is a GSM–affirming number, LOL!

MOTHS FOLLOW THE MILKY WAY: Astronomers come in all shapes and sizes--even invertebrates. A new study published in Nature reveals that Australian moths can see and decipher the night sky. They pay particular attention to the Milky Way and seem capable of navigating using the Carina nebula as a visual landmark.


Above: A male Bogong moth and a diagram of their annual migration.​

Every spring in southeast Australia, billions of Bogong moths take flight under cover of darkness. It's the beginning of an epic migration as much as 1,000 kilometers long. Their destination: a small cluster of caves in the Australian Alps--places the moths have never visited before, yet somehow navigate to with remarkable precision. Their compass, it turns out, is the night sky itself.

QUIET WITH A CHANCE OF X-FLARES: Solar activity is low, with no strong flares observed for more than a week. However, there are currently 10 sunspot groups on the solar disk, and at least one of them has an unstable 'beta-gamma' magnetic field. NOAA forecasters say there is a 10% chance that an X-flare will break the quiet during the next 24 hours.

GEOMAGNETIC STORM WATCH: NOAA forecasters say there is a chance of G2-class geomagnetic storms today, July 23rd, as Earth enters a fast-moving stream of solar wind. The gaseous material is flowing from an equatorial hole in the sun's atmosphere.

BIG FARSIDE SUNSPOT: There's a sunspot on the farside of the sun so large, it is affecting the way the whole sun vibrates. It's the big black blob in this helioseismic image of the whole sun. The sunspot will turn to face Earth about 10 days from now
