[ADXA] Unexpected CME impact

[Bill Priakos]

UNEXPECTED CME IMPACT: A CME was supposed to narrowly miss Earth today. Instead, it delivered a direct hit. NOAA's DSCOVR spacecraft recorded the impact<https://www.spaceweather.com/images2024/17dec24/impact2.jpg> on Dec. 17th (0519 UT). Conditions appear favorable for G1<https://www.spaceweather.com/glossary/g1.jpg> to G2<https://www.spaceweather.com/glossary/g2.jpg>-class geomagnetic storms in the hours ahead.

THE FARSIDE OF THE SUN IS ACTIVE: Over the past week, three halo CMEs have exploded from the farside of the sun. Here is the latest on Dec. 15th:

We can't see what's back there, but it is probably a large sunspot group crackling with activity. The sun's rotation will turn it toward Earth next week. Solar flare alerts: SMS Tex<https://spaceweatheralerts.com/>t<https://spaceweatheralerts.com/>

Note: On Nov. 26, 2024, a flood at Stanford University damaged a number of important SDO data servers. Repairs will not be completed until 2025. As a result, for the foreseeable future, Daily Sun images will be coming from readers of Spaceweather.com. Thank you, citizen scientists!
