We are nearing Solar Maximum, which means that we will have some effects to radio spectrum telecommunications, like the X1.4 flare detailed below:
NASA has confirmed that a powerful X-class solar flare erupted from the sun on Apr. 24. Thanks to the space agency’s Solar Dynamics Observatory, there is photographic evidence of the solar event.
According to NASA, a solar flare is a “sudden, rapid and intense variation in brightness.” A flare takes place when magnetic energy that has accumulated in the solar atmosphere is suddenly released.
While harmful radiation from a flare cannot penetrate Earth’s atmosphere to physically impact humans on the ground, it can impact the atmosphere in the layer where GPS and communications signals travel.
