Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2026-05-13T07:22Z ( DSCOVR: PLASMAG )

All Detecting Spacecrafts:

DSCOVR: PLASMAG

ACE: SWEPAM

ACE: MAG

Activity ID: 2026-05-13T07:22:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Relatively rapid magnetic field enhancement starting around 2026-05-13T07:22Z from 8nT to 11nT with increases in solar wind speed from 325 km/s to 390 km/s with secondary magnetic field enhancement to 14 nT after 2026-05-13T11:10Z with another rapid increase in velocity. this arrival signature may be associated with the arrival of partial halo CME: 2026-05-10T13:48Z with potential stream interaction region effects and associated coronal hole high speed stream starting around 2026-05-13T11:06Z. The signature is still under analysis.
