24-Hour Solar Wind History
Compare satellite readings (ACE, DSCOVR) and Earth-based measurements. All times in Alaska time.
⏱️ Propagation Time: With current solar wind speed, it will take approximately minutes for the solar wind to propagate from DSCOVR satellite to Earth. The gray "Earth" line on charts shows the current time at Earth. Data to the right is from satellites (future arrival), data to the left has already reached Earth.
