High Speed Stream
Catalog: M2M_CATALOG
Event Time: 2026-01-28T08:08Z ( ACE: SWEPAM )

All Detecting Spacecrafts:

ACE: SWEPAM

ACE: MAG

DSCOVR: PLASMAG

Activity ID: 2026-01-28T08:08:00-HSS-001 (version 2)
Event End Time:
Peak Solar Wind Speed (km/s):
Date of first appearance of coronal hole in EUV at east limb:
Note: The start time of this high speed stream is after a data gap in real time solar wind data from 2026-01-28T07:08Z to 2026-01-28T08:08Z. The high speed stream is characterized by an increase in solar wind speed from approximately 470 km/s to approximately 650 km/s, an increase in temperature, and a decrease in density. Magnetic field components gradually enhanced from approximately 5nT to 11nT. The candidate coronal hole can be seen centered around N05 and crossed the central meridian as seen in SDO AIA 193 imagery on 2026-01-25.
