The CMEs that arrived today had very little impact – they raised Solar Wind Speed and Solar Wind Density a bit, they didn’t create any Geomagnetic Storms, they didn’t suppress Electron Saturation. . We had mainly B Class Solar Flares today. Only 2 low-level C […]

June 13, 2026 @ 10:20 UTC (UPDATED) What appears to be a shock passage was detected by the ACE spacecraft at 09:56 UTC (June 13). This is possibly the CME observed leaving the Sun on June 11 arriving a little later than predicted. The solar […]

Geomagnetic storms are possible today, June 13th, when a halo CME is expected to hit Earth’s magnetic field. NOAA forecasters are predicting a G2-class (Moderate) storm. Yesterday, at 9:15 p.m. CEST, there was a significant filament eruption near the eastern edge of the sun. An […]

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. […]
