🌌Space Weather
Space weather conditions are currently quiet.
R0 - S0 - G0
Next 24 Hours: For satellite owner/operators, the absence of radio blackouts means reliable communication with your satellites is preserved, facilitating operational efficiency. Ground-based radars and telescopes will also benefit with minimal interference, ensuring optimal observation conditions. Satellite communication users are in a good position as there are no risks of solar radiation storms, contributing to stable communications. However, with moderate geomagnetic activity, there may be slight drag impacts on Low Earth Orbit (LEO) satellites, which operators should monitor.
Beyond: Looking ahead from June 9 to July 5, 2025, satellite owner/operators should prepare for potential R1-R2 (Minor-Moderate) radio blackouts, especially due to multiple active regions on the Sun’s disk and upcoming solar activities. The good news is that no proton events are anticipated at geosynchronous orbit, which limits risks to satellite systems. The forecast indicates elevated levels of greater than 2 MeV electron flux, peaking during mid-June and late June, likely affecting satellite operations. The geomagnetic activity is projected to experience some fluctuations with G1 (Minor) to G2 (Moderate) storms expected due to coronal hole high-speed stream influences, particularly on key dates in June. While LEO satellites might face increased drag during these storms, communication and operational capacities are expected to remain stable during quieter periods.
