A second strong solar storm this week is predicted to slam Earth Wednesday, causing fluctuations in the power grid and GPS while sparking bright auroras across the world.
According to SpaceWeather.com, a “coronal mass ejection” erupted Monday and is expected to hit the Earth with electromagnetic radiation starting Wednesday at about 10 p.m. PDT and until Thursday.
At the same time, a geomagnetic storm that began Monday continues to rage on at severe levels, pushing glowing polar auroras to places where most people can easily see them.

I kind of wonder if they don’t supercharge our storms. Last night’s storm was spectacular here. Steady lightning.

A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 8 (NOAA Scale
G4).
The greatest expected 3 hr Kp for Jun 23-Jun 25 2015 is 6 (NOAA Scale
G2).

18-21UT 6 (G2) 5 (G1) 5 (G1)
21-00UT 5 (G1) 6 (G2) 5 (G1)
Rationale: The geomagnetic field is expected to remain agitated with
G1-G2 (Minor - Moderate) for the remainder of today, day one (23 Jun),
in continued response to the 21 Jun CME. The 22 Jun CME is expected to
arrive late on day two (24 Jun) with G2 levels at onset, and will
likely enhance geomagnetic conditions to G3 (Strong) levels in the early
hours of day three (25 Jun), before conditions taper off over the day.
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-13 over the past 24 hours, was
above S-scale storm level thresholds.
Solar Radiation Storm Forecast for Jun 23-Jun 25 2015
Jun 23 Jun 24 Jun 25
S1 or greater 99% 99% 95%
Rationale: The greater than 10 MeV proton flux is expected to remain
above S1 levels on days one through three (23-25 Jun). Further
enhancement, possibly to S3, is expected with the arrival of the latest
CME by day three (25 Jun).
C. NOAA Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.
Radio Blackout Forecast for Jun 23-Jun 25 2015
Jun 23 Jun 24 Jun 25
R1-R2 75% 75% 75%
R3 or greater 20% 20% 20%
Rationale: Solar activity is expected to reach (R1-R2, Minor-Moderate)
radio blackout levels throughout the period (23-25 Jun) with a slight
chance for an isolated (R3-Strong) event.

How does it affect the people on the space station, I wonder?
No doubt due to GoreBull warming.
