3D Sun Alert: A coronal mass ejection (CME) hit Earth's magnetic field at -0200 on Oct 2nd sparked a G2-class geomagnetic storm. G2 Class Definition: Strength: Moderate Power systems: High-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage. Spacecraft operations: Corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions. Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.)**. PostScript: I was in South Iceland looking at the sky at -0200 on Oct 2nd. In fact, I was looking at the sky at -0300, -0400, -0500 and -0600 before it started getting light. And I could
