Thankfully, the storm is classified as weak.

High-speed solar winds from a “hole” in the sun’s atmosphere are set to hit Earth’s magnetic field on Wednesday (Aug 3.), triggering a minor G-1 geomagnetic storm.

Forecasters at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC) made the prediction after observing that “gaseous material is flowing from a southern hole in the sun’s atmosphere,” according to spaceweather.com

Coronal holes are areas in the sun’s upper atmosphere where our star’s electrified gas (or plasma) is cooler and less dense. Such holes are also where the sun’s magnetic field lines, instead of looping back in on themselves, beam outward into space. This enables solar material to surge out in a torrent that travels at speeds up to 1.8 million miles per hour (2.9 million kilometers per hour), according to the Exploratorium, a science museum in San Francisco.

On planets with strong magnetic fields, like our own, this barrage of solar debris is absorbed, triggering geomagnetic storms. During these storms, Earth’s magnetic field gets compressed slightly by the waves of highly energetic particles. These particles trickle down magnetic-field lines near the poles and agitate molecules in the atmosphere, releasing energy in the form of light to create colorful auroras, similar to the ones that make up the Northern Lights

Note: Earth’s magnetic field stems from a complex geo-dynamo produced in the core of our planet. Its key role in ensuring the long-term habitability of Earth is well-established.

The storm produced by this debris will be weak. As a G1 geomagnetic storm, it has the potential to cause minor fluctuations in power grids and impact some satellite functions — including those for mobile devices and GPS systems. It will also bring the aurora as far south as Michigan and Maine.

This storm comes as the sun ramps up into its most active phase of its roughly 11 year-long solar cycle.

Astronomers have known since 1775 that solar activity rises and falls in cycles, but recently, the sun has been more active than expected, with nearly double the sunspot appearances predicted by NOAA. Scientists anticipate that the sun’s activity will steadily climb for the next few years, reaching an overall maximum in 2025 before decreasing again. 

Scientists think the largest solar storm ever witnessed during contemporary history was the 1859 Carrington Event, which released roughly the same energy as 10 billion 1-megaton atomic bombs. After slamming into Earth, the powerful stream of solar particles fried telegraph systems all over the world and caused auroras brighter than the light of the full moon to appear as far south as the Caribbean. If a similar event were to happen today, scientists warn, it would cause trillions of dollars in damage and trigger widespread blackouts, much like the 1989 solar storm that released a billion-ton plume of gas and caused a blackout across the entire Canadian province of Quebec, NASA reported.

    It’s just a matter of time before another Carrington Event hits us.

    Anyone for a Faraday cage?

    Faraday cage will keep you safe? Perhaps you ought also put your trust in Him whom Faraday himself put his trust in to keep him ‘eternally safe’?

    “Speculations? I have none. I am resting on certainties. I know whom I have believed and am persuaded that he is able to keep that which I have committed unto him against that day.”
    – Faraday – When asked about his speculations on life beyond death, as quoted in The Homiletic Review? (April 1896), p. 442

    “I shall be with Christ, and that is enough.”
    – Faraday – Last words, answering the question “Have you ever pondered by yourself what will be your occupation in the next world?”, as quoted in The Speaker’s QuoteBook (1997) edited by Roy B. Zuck, p. 108

    of note:

    “The book of nature which we have to read is written by the finger of God.”
    – Faraday, as cited in Seeger 1983, 101.

    Man of Science, Man of God: Michael Faraday
    Who: Michael Faraday
    What: Father of Electromagnetism
    When: September 22, 1791 – August 25, 1867

    Michael Faraday was arguably the best experimentalist in the history of science.,,

    Faraday invented the Faraday cage which suggests he did not trust his God to provide protection against electromagnetic fields at least.

    Seversky at 8,

    An expert on electromagnetism? Are you? Do you know the purpose of a Faraday cage? Or is this just another ‘I hate God! He’s just a man!’ posts? God does bad things, according to you. God should be judged like any man, according to you. I can find no other way to put this: you’re wrong.

    Seversky, apparently your understanding of Theology is as naive as that of Pentecostal snake handlers.

    Like the old Marine Corp commercial from 1970, as far as this world is concerned, Christianity “never promised you a rose garden.”

    John 16:33
    “I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world.”

    John 16:20-22
    Very truly I tell you, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy. A woman giving birth to a child has pain because her time has come; but when her baby is born she forgets the anguish because of her joy that a child is born into the world. So with you: Now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy.
