All Detecting Spacecrafts:

ACE: SWEPAM

ACE: MAG

DSCOVR: PLASMAG

Activity ID: 2025-01-13T06:20:00-HSS-001 (version 1)
Event End Time:
Peak Solar Wind Speed (km/s):
Date of first appearance of coronal hole in EUV at east limb: 2025-01-06
Note: Increase in solar wind speed from approximately 400 km/s to 480 km/s. Preceded by an enhancement and pileup in magnetic field components around 2025-01-13T04:15Z and a slight increase in density, followed by a decrease in density as the speed increased. As the solar wind speed increased, an increase in temperature is also observed. The candidate coronal hole can be seen crossing disk center in SDO AIA imagery on 2025-01-10, centered around latitude N10.
