Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2024-04-19T04:53Z ( DSCOVR: PLASMAG )

All Detecting Spacecrafts:

DSCOVR: PLASMAG

ACE: SWEPAM

ACE: MAG

Activity ID: 2024-04-19T04:53:00-IPS-001 (version 3)
Quality of ICME Signature: 2 (clear signatures)
Note: Sudden increase in B-total from 5nT to 15nT and rotation of B-field components observed in DSCOVR, which was the primary spacecraft at the time. Signature also observed in ACE. Simultaneous sudden increase in density at 2024-04-19T04:53Z. Bz remains predominantly in the negative regime. A sudden increase in temperature and speed is observed later at 2024-04-19T13:44Z, likely indicating the arrival of a flux rope. This signature observed at L1 is likely associated with the arrival of CME:2024-04-15T06:48Z.
