Enhancing Preparedness for Space-Weather Events

Our Nation’s security, economic vitality, and daily functioning depend on the reliable operations of satellites and aircraft, communications netwo

Space weather refers to variations in the space environment between the sun and Earth (and throughout the solar system). In particular, space weather describes the phenomena – solar flares, solar energetic particles, and coronal mass ejections – that impact systems in orbit and on Earth. In recent years, the Obama Administration has played an active role in maintaining and advancing the Nation’s ability to forecast and mitigate the various impacts of space weather. This work has included taking steps to replace aging satellite assets essential to monitoring and forecasting space weather, proposing space-weather standards for both the national and international air space, developing regulations to ensure the continued operation of the electric grid during an extreme space weather event, proposing a new option for replacing crucial Extra High Voltage (EHV) transformers damaged by space weather, and developing domestic production sources for EHV transformers.rks, navigation systems, and the electric power grid. As these and other, similar technologies and infrastructures become increasingly ubiquitous and interdependent, the United States – and indeed, the world – faces greater risks from the threats posed by space weather events.

Solar Flares are classified by "classes". These classes represent how strong the solar flare is, according to the energy that was released. 

We useally here about two classes: X-Class and M-Class, however there is 4 diffrent classes and they rank B-Class, C-Class, M-Class and X-Class, being the strongest.
