Wind: light air, northeast, speed 4 km/h Wind gusts: 11 km/h Relative humidity: 74% Atmospheric pressure: 1008 hPa Waves in the sea: calm (glassy), wave height of 0,1 m Amount of precipitations: 0,1 mm Visibility: 100% Water temperature in the sea: +29 °C Geomagnetic Field:Strong Storm
Direction of wind shown by smoke drift, but not by wind vanes.
At Sea:
There are very weak waves at sea. Ripples with the appearance of scales are formed, but without foam crests.
Power systems: Voltage corrections may be required,
false alarms triggered on some protection devices.
Spacecraft operations: Surface charging may occur on satellite components,
drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems.
Other systems: Intermittent satellite navigation and low-frequency radio navigation
problems may occur, HF radio may be intermittent,
and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic latitude.).
