Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2025-04-15T16:36Z ( DSCOVR: PLASMAG ) Quality of ICME Signature: -1 (unspecified) Note: Characterized by an amplification of magnetic field components with Btotal increasing from 6nT at 2025-04-15T16:36Z to 17nT at 16:38Z. A subsequent increase in solar wind speed is observed, increasing from 400 km/s at 2025-04-15T16:36Z to ~480 km/s at 16:37Z, with density increasing to 35 p/cc at this time as well. This signature is likely associated with the arrival of CME: 2025-04-13T08:00Z and CME: 2025-04-13T08:12Z, with possible influence from the arrival of CME: 2025-04-12T00:48Z, CME: 2025-04-13T00:12Z and CME: 2025-04-13T07:48Z. This arrival signature is still developing and analysis is ongoing. Submitted on 2025-04-15T17:08Z by Mattie Anastopulos A Notification with ID 20250415-AL-002 was sent on 2025-04-15T17:20Z |
