Activity ID: 2025-10-17T13:25:00-IPS-001 (version 2)
Quality of ICME Signature: 2 (clear signatures)
Note: Characterized by a sudden increase in B-total from 5 nT to 12 nT, and peaking at 14 nT. Rotation in at least two B-field components (By and Bz) is observed. Solar wind speed increases from already elevated 600 km/s to over 800 km/s, ion density increases from the already elevated 10 pp/cc to just under 20 pp/cc, and ion temperature has a brief increase.
