The Sun's Fury Unleashed: CME Arrives!

A significant Coronal Mass Ejection (CME) from a recent M4.4 solar flare, which launched from the Sun on August 5th, has now reached Earth. This event, coupled with a coronal hole high-speed stream (CH HSS), is expected to trigger geomagnetic storming on August 8th and 9th. A G2 (Moderate) watch was issued for August 8th, indicating the onset of this powerful space weather phenomenon.

CME Impact

What You Need to Know:

  • The Event: The video captured shows the CME over a 3.5-hour period from 11:00 to 14:30 UTC on August 8, 2025.
  • Geomagnetic Storming: The combined effects of the CME and the high-speed solar stream are causing geomagnetic storming, which can have various impacts on Earth's magnetosphere and technology.
  • Visibility: While specific visibility details for how far south geomagnetic storms might be observed are still being confirmed, past reports have indicated visibility in regions like Maine and Michigan during similar events.
  • Scientific Observation: It's remarkable that we can observe and track these distant solar events from space, highlighting the capabilities of our monitoring satellites.

This is a stark reminder of the dynamic and powerful nature of our Sun and the importance of space weather monitoring. Stay tuned for further updates on the progression of this geomagnetic storm!
