## Summary:
Ongoing space weather storm in the Earth's magnetosphere. Geomagnetic Kp index has reached level 6.33 (moderate) during the synoptic period 2026-05-04T18:00Z to 2026-05-04T21:00Z.
The storm is caused by the Interplanetary Shock with ID 2026-05-04T04:10:00-IPS-001 and the arrival of CME with ID 2026-04-30T12:38:00-CME-001 and/or CME with ID 2026-04-30T18:24:00-CME-001.
NASA spacecraft at GEO, MEO, polar and other orbits passing through or in the vicinity of the Earth's ring current and auroral regions can be impacted.
Activity ID: 2026-05-04T18:00:00-GST-001.
