Space weather conditions are currently quiet.
R0 - S0 - G0
Next 24 Hours: No risk of radio blackouts or solar radiation storms is expected in the short term, providing a stable environment for satellite operators and ground-based radar systems. However, a G1 (Minor) geomagnetic storm is anticipated on 28 May due to the onset of a coronal hole high-speed stream (CH HSS). While no significant solar wind features are forecasted, operators should remain vigilant, as there is a slight chance of the greater than 10 MeV proton flux reaching S1 (Minor) levels between 27-29 May. Additionally, radio blackout levels may reach R1-R2 (Minor-Moderate) with a potential for isolated R3 (Strong) events during this period, which could affect communications for some satellite users.
Beyond: From 26 May to 21 June, solar activity is expected to ramp up to moderate levels (R1-R2/Minor-Moderate), particularly as Region 4098 approaches the west limb of the Sun. There remains a chance for M-class X-ray activity, which could impact satellite operations and ground-based telescopes due to increased radiation levels. During this forecast period, no proton events are expected at geosynchronous orbit; however, expect high levels of the greater than 2 MeV electron flux around 30 May - 05 Jun and 14-21 Jun due to recurrent coronal hole influences. Geomagnetic conditions are likely to remain mostly elevated, with G1 (minor) storms anticipated on 13-14 June and active conditions potentially affecting operations on several dates throughout this forecast. Quiet conditions will only occur on 08-09 June, so satellite operators and communication users should stay updated and plan accordingly.
