A coronal mass ejection (CME) passed Earth at UTC (Feb 4). A geomagnetic sudden impulse measuring 16 nT was detected by a magnetometer in Boulder, Colorado. So far the impact appears to be fairly mild, however active (Kp4) to minor (G1) storm conditions may be possible today.

A strong solar flare was just observed beyond the southeast limb. Although peaking at M3.3, it was likely stronger because the source is now yet in view. A CME is now just becoming visible and will be directed away from Earth. We will begin to see the source later this week.
