Aurora chasers, now is the time! Heads up for the next couple of days for enjoying beautiful auroras. That means auroras are possible at northern latitudes, possibly as low as Montana and North Dakota in the U.S. For today and tomorrow, the Space Weather Prediction Center issued a double alert for G1 levels. For most of yesterday, October 28, the index stayed at Kp 4. The threshold occurred at 8:05 UTC on October 29, 2022. The planetary Kp index reached level 5, G1 (minor) on the NOAA scale. As we write this article early on October 29, the disturbance is ongoing. Today’s top news: A G1 (minor) geomagnetic storm is here. Sun activity October 29: Double aurora alert for northern US That’s good news for Northern Lights fans, but there could be some serious connectivity and power problems for civilization, especially considering it comes at a time when we’re more dependent on satellite communications than ever before.Octosun activity: Double alert on auroras forecast for today, October 29, and tomorrow, October 30, 2022. Many space watchers forecast an increasing number of sunspots and solar flares between now and sometime in the next few years before activity resumes.īy some accounts, this current solar cycle phase called solar maximum has already been more active than expected and may be one for the record books. The Sun is moving toward the peak of activity in its 11-year cycle of sunspot activity. It also enlarges the aurora borealis and aurora australis, making them potentially more active and visible at lower latitudes.Īll this could be just the beginning. Such space weather could be harmful to spacecraft in orbit and could deliver small doses of radiation to astronauts on the International Space Station. More from forbes A ‘dangerous’ sunspot with major solar flare potential is pointing to Earth By Eric Mack According to NOAA’s Space Weather Prediction Center, the CME is expected to reach the planet by Tuesday and could cause a geomagnetic storm over Earth. The sun gave off several CMEs as well as two strong M flares over the weekend, which move much slower than the particles in the flares.
In the most extreme cases, bursts and bursts of charged plasma called coronal mass ejections (CMEs) can often affect electrical equipment and grids on the ground. However, flares can also briefly disrupt radio and satellite communications in the part of the world that is in line of fire, including navigation systems such as GPS. These bursts of radiation travel at the speed of light, reaching Earth in less than ten minutes, but our planet’s magnetosphere prevents most energetic explosions from reaching the surface. Solar flares are bursts of energetic particles that usually erupt from sunspots on the Sun’s surface. While an X1 is a significant flare, flares up to X28 have been recorded which, according to NASA, overloaded the sensor during the most powerful flare in 2003. Each letter is ten times more powerful than the previous, so an X-flare is ten times more powerful than an M flare and 100 times more intense than a C flare. Flares are grouped by intensity into C, M and X class flares with X flares being the most powerful. The eruption was classified as an X1 class flare, peaking at 4:25 p.m. NASA’s Solar Dynamics Observatory and other Sun watchers picked up an intense X-class flare from our local star on Sunday afternoon, the most powerful burst of energy seen from the Sun since May 10. A powerful X-flare from the Sun as recorded in 2003.
