Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: STEREO A
Event Time: 2026-01-29T03:19Z ( STEREO A: IMPACT )

All Detecting Spacecrafts:

STEREO A: IMPACT

STEREO A: PLASTIC

Activity ID: 2026-01-29T03:19:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterized by the smooth rotation and amplification of magnetic field components following a data gap spanning from 2026-01-28T16:41Z to 2026-01-29T03:19Z. B_x and B_z remain smooth while B_y rotates from approx. -3nT to approx. 3nT. Minor amplifications in density and velocity are also noted, but data remains sparse. This signature may be associated with CME: 2026-01-25T12:00Z , CME: 2026-01-25T20:12Z and/or CME: 2026-01-25T21:48Z, as all three events were anticipated to arrive between 2026-01-28T06:58Z and 2026-01-28T21:00Z.
