M9.3 Eruption / Earth Directed CME / Radiation Storm

Strong G3 Storm Watch
Possibly a treat in the works for aurora sky watchers. A Strong (G3) geomagnetic storm watch will be in effect beginning Wednesday (September 6) when the coronal mass ejection (CME) observed Monday is expected to sweep past Earth. Sky watchers across middle to high latitudes should be alert during the next 48 hours. More updates regarding this to follow.

M5.5 Eruption / Earth Directed CME / Radiation Storm
Moderately strong M5.5 solar flare event observed around region 2673 on Monday evening.UPDATE: An update regarding the M5.5 solar flare event around region 2673 this evening at 20:33 UTC. The flare was associated with a Type II radio emission with an estimated velocity of 1472 km/s, along with a 10cm radio burst (TenFlare) lasting 52 minutes and measuring 1600 solar flux units (SFU). Low energy proton levels as measured by the GOES-13 spacecraft are currently on the rise. Updated coronagraph imagery courtesy of LASCO C3 shows a coronal mass ejection (CME) leaving the sun and at least a portion of this cloud may be Earth directed. More updates to follow.
