Catalog: M2M_CATALOG
Event Time: 2026-06-03T23:00Z ( STEREO A: IMPACT )

All Detecting Spacecrafts:

STEREO A: IMPACT

STEREO A: PLASTIC

Activity ID: 2026-06-03T23:00:00-HSS-001 (version 1)
Event End Time:
Peak Solar Wind Speed (km/s): 500.0
Date of first appearance of coronal hole in EUV at east limb:
Note: Characterized by an increase in solar wind speed from ~400 km/s to ~500 km/s and concurrent temperature increase. An increase in density is observed leading up to the start time, then decreases with the speed and temperature increase. Also characterized by an enhancement starting at 2026-06-03T15:00Z in magnetic field components (B_t: approx. 5nT to a peak of 15nT , B_x: approx. 5nT to a peak of -15nT , B_y: approx. 0nT to a peak of 15nT , B_z: approx. -5nT to a peak of -17nT).
