A solar storm is expected to hit Earth on WEDNESDAY: The ‘hole’ in the sun boosts solar winds that could weaken power grids and bring stunning auroras to northern regions
- A coronal hole in the face of the sun reinforces the solar winds that head towards Earth
- This triggered a warning for a minor G1-class geomagnetic storm to hit Earth on Wednesday
- It is the weakest storm on a scale of five and can only weaken power grid fluctuations or have a slight impact on satellites
Earth is under a solar storm warning for August 3, as the National Oceanic and Atmospheric Administration (NOAA) announces that there is a chance of a minor G1-class geomagnetic storm to hit our planet.
A G-1 storm can weaken power grid fluctuations, impact satellites and potentially trigger auroras in regions around the north pole – in which case electric colors will be seen in the sky above Canada and Alaska. However, it is the lowest of the five rated by NOAA.
The geomagnetic storm is caused by a coronal hole in the southwest region of the sun’s face which is spitting out “gaseous matter”.
Mike Cook, who works in space weather operations, told DailyMail.com that the hole improved solar wind speed by throwing solar winds into a stream. He also notes that it’s expected to induce G-1 conditions, but we’ll have to “see if that comes true in the next 24-48 hours.”

NOAA’s Space Weather Prediction Center classifies geometric storms into five stages – with one being weakest and five being strongest.
And the one set for this week will have very little impact on satellites and technologies on Earth. This can, however, confuse migrating animals that use the earth’s magnetic field as a navigation tool.
Indeed, geomagnetic storms trigger electrical currents in the magnetosphere and ionosphere when the area shaped by the Earth’s magnetic field is compressed and disturbed.
There was also a C9.3 flare that shot out of the sun on Sunday. Class C flares are small with few noticeable consequences on Earth, but they are exciting to see.

This one, however, didn’t erupt on the side of the sun facing Earth, but it did explode enough to be captured by NASA’s Solar Dynamics Observatory – a craft that has been studying our massive star since its launch in 2010. .
The flare was captured late on July 31. This graphic then shows that the flare was picked up by satellites
It takes 169,090 hours to reach the sun if you are traveling at around 550 miles per hour.
‘Yesterday’s C9.3 eruption was from a region that technically isn’t even on the disc facing Earth yet, it’s just around NE [north eastern] member,” Cook told Dailymail.com.
“And solar flares themselves don’t cause a geomagnetic storm, it’s only if a CME (coronal mass ejection) is associated with an Earth-directed ET flare.
The snake-like filaments are CMEs, which are large expulsions of plasma and magnetic field from the solar corona – the outermost layer of a star’s atmosphere.
Earth experienced a solar storm on July 19 that brought stunning auroras to the northern United States and Canada. Pictured is an image of the aurora above Seattle, Washington
Earth experienced a solar storm on July 19 that brought stunning auroras to the northern United States and Canada.
The storm made headlines over the weekend when Dr Tamitha Skov announced she had spotted a ‘snake-like filament’ on the surface of the sun on Friday – and was heading towards the strike zone earthly.
Auroras were seen earlier Friday morning just as the storm hit, filling the northern sky with stunning electric shades of purples and greens.
Cook DailyMail.com July 19: ‘There have been several CMEs [coronal mass ejections] recent days flares (solar storms) but there is also a coronal hole (black hole like structures) which is at the center of the disk.’
“We should see the impacts of this in the next 2-3 days.”
And that’s right, the cosmic spectacle isn’t over – the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center (SWPC) shows that a G1 class is expected to impact our planet as early as Thursday and late Friday.
