*A BIG SUNSPOT IS EMERGING:*A new and apparently large sunspot is 
emerging over the sun's southeastern limb. Amateur astronomers with 
solar telescopes should point their opticsright here 
<https://spaceweather.com/images2023/08feb23/latest_4096_HMIBC_lab_crop.jpg>to 
see what is coming. This is the same active region that produceda 
dramatic explosion

farside of the sun on Feb. 7th.*Solar flare alerts:*SMS Text

*SOLAR FLARE AND RADIO BLACKOUT:*Two days ago, sunspot AR3213 didn't 
even exist. Now it stretches almost 100,000 km across the surface of the 
sun with at least two dark cores larger than Earth. The fast-growing 
spot iscrackling with solar flares 
<https://spaceweather.com/images2023/08feb23/crackling.jpg>. The 
strongest so far, an M6-class flare on Feb 7th (2307 UTC), caused a 
shortwave radio blackout over the Pacific Ocean:

Mariners and ham radio operators around the Pacific may have noticed 
unusual propagation effects at frequencies below 30 MHz for at least an 
hour after the flare.

This explosion did not produce a CME. However, future explosions might. 
The sunspot has an unstable 'beta-gamma' magnetic field that harbors 
energy for strong flares; NOAA forecasters say there is a 25% chance of 
M-flares and a 5% chance ofX-flares <https://svs.gsfc.nasa.gov/10833>on 
Feb. 8th. The sunspot is almost directly facing Earth, so stay 
tuned.*Solar flare alerts:*SMS Text <https://spaceweatheralerts.com/>.
