Solar Event

Space weather charts indicate a CME arrived around 6/13 at about 4.00a CDT, but it looks like it’s a weak one. It did take Solar Wind Speeds up to ~600 km/sec and the HP Index responded by going from HP = 3.0 to HP = […]

 Another Earth-directed CME? NASA is modeling a filament eruption which may deliver a glancing blow to Earth around June 14 at 17 UT. According to the modeling, we may see a G1-G2 storm if this CME impacts Earth. High hopes, low expectations per usual! […]

A moderate solar storm could bring the northern lights to the northern U.S. and Canada tonight (Friday, June 12) into early Saturday. NOAA has issued a G2 (“moderate”) geomagnetic storm watch for June 13, with G1 watches on either side for June 12 and 14. […]

Well, the CH HSS arrived today. It raised our Solar Wind Speeds and it caused brief Geomagnetic Storms, but at least Electron Saturation dropped for the day… . We had C Class Solar Flares today, but we still have an M Class Solar Flare Watch […]

Geomagnetic activity has been steadily increasing today as high-speed solar wind keeps affecting Earth. This is due to coronal hole influences. Elevated geomagnetic activiy may persist until nightfall for North America. Southern Canada and the northern tier of the U.S. could see lights tonight. — […]

Early estimates of midday to late June 13 look to be spot on, at least with the NOAA/SWPC prediction. Here is their latest model run that captures the two eastward travelling solar storms. As for the south-westward filament launch, I am not so ready to […]

A long-duration C6.7 flare from AR 4465 has sent a coronal mass ejection partially directed at Earth. it’s not squarely aimed at Earth, but both NASA and NOAA think we will get clipped. Coinciding with the onset of a high-speed stream, this weekend could be […]

Geomagnetic Storm: A geomagnetic storm is a major disturbance in the Earth’s magnetosphere. When unusually strong solar wind waves (charged particles from the Sun) pass over the Earth, the effect causes changes in the magnetic field surrounding the planet. Geomagnetic storms can cause disruptions in […]
