It's supposed to be G1, which is the lowest most mild,, wonder why they had a story about it?
Solar storm that could knock out power supplies, damage satellites and trigger auroras slams Earth after THREE massive holes open on the sun
Nasa spotted gaps in the sun, known as a coronal holes, earlier this week
National Oceanic and Atmospheric Administration issued a 'G1' storm watch
This minor storm may have a slight impact on systems on and around the planet
That includes power grid fluctuations and an impact on satellite operations
Images from the SDO show dark patches on the sun's surface, the location from which the solar winds originated.
Three such holes appeared between Tuesday and Friday last week.
In a written statement last week, a spokesman for Nasa said: 'For much of this week the sun featured three substantial coronal holes.
G1 - Minor
Power systems: Weak power grid fluctuations can occur.
Spacecraft operations: Minor impact on satellite operations possible.
Other systems: Migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (northern Michigan and Maine).
