Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2026-02-14T19:39Z ( ACE: MAG )

All Detecting Spacecrafts:

ACE: MAG

ACE: SWEPAM

DSCOVR: PLASMAG

Activity ID: 2026-02-14T19:39:00-IPS-001 (version 1)
Quality of ICME Signature: 2 (clear signatures)
Note: Characterized preliminarily by a jump from an already elevated B_total around 9.9nT to 15nT. B_z largely southward in the early signature, around -10nT. Solar wind speeds slowly rise starting around 2026-02-14T15:30Z from ~370 km/s to ~450 km/s as of 2026-02-14T21:00Z, with a sharp increase in temperature and decrease in density observed starting around 2026-02-14T18:30Z. This arrival signature is likely associated with a corotating interaction region associated with the 2024-02-14 high speed stream.
