NASA-French Satellite Captures Large-Scale River Waves
In an unprecedented achievement, the NASA-French satellite mission SWOT has documented large-scale river waves in the United States. These waves, ranging from 47 to 166 miles in length, were observed in rivers across Montana, Texas, and Georgia. Utilizing satellite data, researchers could measure both the height and speed of these potentially hazardous flood waves.
The mission’s novel observations offer critical insights into flood dynamics and risks associated with extreme weather events. Such data underscores the valuable contributions of satellite technology in environmental monitoring and disaster management.

🌌Space Weather
Current space weather shows Radio blackout conditions (R1).
R1 - S0 - G0
Next 24 Hours: No risk of radio blackouts is expected, allowing satellite operators and communication users to maintain normal operations without concern for disruptions. Ground-based radars and telescopes will function optimally during this period, providing clear observational opportunities. Additionally, there are no risks reported for solar radiation storms, which is positive news for those relying on satellite technologies. Drag impacts to Low Earth Orbit (LEO) satellites will also remain manageable, as no significant geomagnetic activity is anticipated.
Beyond: The forecast for solar and geomagnetic activity from 19 May to 14 June 2025 indicates a general low level of solar activity, although the potential for R1-R2 (Minor-Moderate) radio blackouts exists. Thankfully, no proton events are expected at geosynchronous orbit, which is a relief for satellite operators. However, the greater than 2 MeV electron flux at geosynchronous orbit is likely to increase to high levels during specific periods (19-23 May, 29 May - 05 Jun, and 14 Jun) due to recurrent coronal hole activity.
Geomagnetic conditions may experience elevated levels primarily due to these recurrent coronal hole features. G2 (moderate) conditions are likely on 29 May and 13 Jun, while G1 (minor) conditions are expected on the 19 May, 28 May, and 14 Jun. Active conditions will likely occur from 30 May - 01 Jun and on 10 Jun, with unsettled periods expected intermittently. For those operating satellites, while active and unsettled conditions may introduce some challenges, quiet conditions are projected for the last few days of this outlook period, offering a window for stable operations.
