Two Space Weather Alerts in last 24 hours. High Radio and X-Ray Emissions

SpaceWeather

Were getting very close to Solar Max and the Sun has been becoming active. In the last 24 hours there has been a space weather alert for X-Ray Flux exceeding M5 and type two Radio Emissions.

Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.

The X-Ray event area of impact centered on sub-solar point on the sunlit side of Earth. Extent of blackout of HF (high frequency) radio communication dependent upon current X-ray Flux intensity.
