Warnning: SPArToS is an experimental product under validation process.
SPArToS (from the Spanish for Solar Storms Arrival Prediction System) is an early-alert system to forecast the arrival of coronal mass ejections and associated shock waves to Earth's neighborhood. SPArToS is based on the Piston-Shock model. SPArToS provides to the user the time and date at which a potentially dangerous solar storm would arrive to the Earth's neighborhood.
A list of all our arrival predictions can be found at our analyzed events catalog.

ISSUED: [05/31/2025-17:44 UTC] A halo-CME is reported, with its source region located near the center of solar disk (N14E10). The orientation of the magnetic structure that likely originated the CME, along with the position of the associated active region, make it highly possible for the center of the CME structure to impact the Earth's space environment. The initial velocity of the CME suggests that the event may drive a shock wave. Therefore, the arrival of the frontal region of a shock wave into the Earth's space environment is expected prior to the arrival of the CME. The original orientation of the magnetic structure in the solar atmosphere, the arrival velocity, and the arrival of the shock wave suggest that the event may be geoeffective (Kp <=8). |
