High Speed Stream
Catalog: M2M_CATALOG
Event Time: 2026-03-13T08:08Z ( ACE: SWEPAM )

All Detecting Spacecrafts:

ACE: SWEPAM

ACE: MAG

Activity ID: 2026-03-13T08:08:00-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: 2026-03-06
Note: Coronal hole high speed stream characterized by an increase in solar wind speed from approximately 395 km/s to approximately 540 km/sThe candidate coronal hole can be seen first crossing the central meridian on 2026-03-12. Accompanied by an increase in temperature from approximately 54000K to 300000K. Preceded by an enhancement in magnetic field components starting at 2026-03-13T07:06Z from 6nT to 10nT, reaching 13nT. An increase in density is seen at the same time as this magnetic field enhancement. Upon coronal hole high speed stream onset, the density decreases.
