Aurora, Solar flare, Sun Deadly Solar Flares & Coronal Mass Ejections – We Must Prepare

Occasionally the earth is caught in its sights when a coronal mass ejections magnetic field is misaligned to earths, a dangerous geomagnetic storm can occur if were not prepared. This could be a multi trillion dollar calamity with potential loss of life. Looking closely at the corona, the suns outermost layer, astronomers can see wisps, loops, tendrils and even streams of hot ionized plasma. These are caused by the suns magnetic field as hot charged particles follow the magnetic field lines between various solar components, lines enter and depart the sun in a chaotic manner, with powerful magnetic fields that loop back split apart and reconnect on a regular basis. These magnetic reconnection events can cause not just rapid changes in the intensity and direction of the field near the sun, but also rapid acceleration of charged particles. This can result in the emission of solar flares as well as coronal mass ejections, solar flares and coronal. Mass ejections are composed of fast moving charged particles emitted by the sun, primarily protons and other atomic nuclei. The sun regularly emits a continuous stream of these particles called the solar wind in our solar system. Most space weather occurrences are benign, at least from the earths perspective. An incident represents a threat only when it points directly at us. Our first lines of defense are sun. Monitoring, satellites and observatories most of the time, the majority of solar weather events pose no immediate threat and simply calls a spectacular auroral display until recently, larger events pose little real threat to earth, but now electricity based infrastructure pervades our planet.

Solar events can cause massive amounts of electrical current to flow through the wires that connect our infrastructure, causing disruption. Consumer electronics, arent a major issue. If you knew a solar storm, was coming and disconnected everything in your house. Most of your gadgets would be just fine. The main problem is in our infrastructure for large scale. Electricity production and transmission uncontrollable surges have the potential to knock down power stations and pump far too much current far too quickly into cities and buildings essentially frying their circuits by disrupting heat, cooling, water and power. A major solar event could kill thousands, or perhaps millions of people to be serious about preventing harm from a solar event. We need early detection only by monitoring the magnetic fields of charged particles from the sun and comparing them with the orientation of the earths magnetic field. Can we tell if an event will be potentially disastrous for our planet in the past? Satellites could only alert us when solar particles were nearly upon us providing less than an hour to prepare for their arrival. We recently got an upgrade with the national science foundations, new observatory, the daniel k, inoa, solar, telescope or dkist. Four of dkis five scientific instruments are spectropolarometers built and optimized to detect the suns magnetic characteristics. Dkis lets us measure the magnetic field in all three visible layers of the sun, the photosphere, the chromosphere and the solar corona. With this knowledge, we can estimate the orientation of a coronal mass ejections magnetic field just after its released, and we can quickly evaluate whether the expelled material presents a risk to earth.

Instead of less than an hour. We might have three or four days warning the time that ejected, coronal material usually takes to reach earth. This is better, but at large were still not really prepared. Most electric stations and substations lack sufficient grounding to divert huge induced currents into the earth rather than into homes, businesses and industries. Early warning to power companies to cut off current in their electrical grid could reduce the risks and severity of fires, but this has never been tested. Creating official recommendations for how to cope in a household would be a good step as well.
