STRONG GEOMAGNETIC STORM PREDICTED: A CME hurled into space by Saturday's X4.5-class solar flare will graze Earth on Sept. 16th, according to a NASA model<https://www.spaceweather.com/images2024/14sep24/nasamodel.gif>. NOAA forecasters are predicting a strong G3<https://www.spaceweather.com/glossary/g3.jpg>-class geomagnetic storm when the CME<https://www.spaceweather.com/images2024/14sep24/lopsided_halo.gif> arrives. During G3 storms, auroras can sometimes be seen with the naked eye from mid-latitudes--e.g., as far south as California, Missouri and Colorado in the USA. On Sept. 16th, however, bright moonlight could mitigate the display. Aurora alerts: SMS Tex<https://spaceweatheralerts.com/>t<https://spaceweatheralerts.com/>

SIGNIFICANT X-CLASS SOLAR FLARE: New sunspot AR3825 erupted on Sept. 14th, producing a very strong X4.5-class<https://svs.gsfc.nasa.gov/10109> solar flare. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:

Radiation from the flare ionized the top of Earth's atmosphere, resulting in a deep shortwave radio blackout over South America and the mid-Atlantic Ocean: map<https://www.spaceweather.com/images2024/14sep24/blackoutmap.jpg>. Ham radio operators and mariners may have noticed loss of signal at frequencies below 30 MHz for as much as 30 minutes after the flare's peak (1529 UTC).

The explosion also hurled a CME<https://www.spaceweather.com/images2024/14sep24/lopsided_halo.gif> into space, and a NASA model<https://www.spaceweather.com/images2024/14sep24/nasamodel.gif> confirms that it has an Earth-directed component. Strong G3<https://www.spaceweather.com/glossary/g3.jpg>-class geomagnetic storms are possible when the CME grazes Earth on Sept. 16th.
