High Speed Stream
Catalog: M2M_CATALOG
Event Time: 2023-03-24T14:19Z ( DSCOVR: PLASMAG )

All Detecting Spacecrafts:

DSCOVR: PLASMAG

ACE: SWEPAM

ACE: MAG

Activity ID: 2023-03-24T14:19:00-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: 2023-03-14
Note: The HSS arrival signature is marked by a gradual increase in solar wind speed from 400 to over 550 km/s, accompanied by the ion temperature increase. This high speed stream likely from the large southern coronal hole follows the L1 passage on 2023-03-23 and 24 of one or two (combined) CMEs from 2023-20 causing significant geomagnetic disturbance.
