 DONKI: View SW Activity
Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2025-06-02T20:02Z ( ACE: MAG )
All Detecting Spacecrafts:
ACE: MAG
ACE: SWEPAM
DSCOVR: PLASMAG
Activity ID: 2025-06-02T20:02:00-IPS-001 (version 4)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterized by a brief jump in Btotal from an already elevated 10nT background (due to waning influence from previous IPS 2025-06-01T05:22Z) to 12.4nT, rising to around 14.5nT by 2025-06-02T20:29Z. Also observed a distinct rise in solar wind speed from around 580 km/s to around 660 km/s at this time, with a small elevation in temperature and density timelines at the start of this signature. This may be the arrival of CME 2025-05-31T14:23Z expected at 2025-06-02T22:43Z (+-7 hours).
