But according to the Solar Influences Data Analysis Center, there have been no other Earth-directed CMEs observed in the past 24 hours other than the one spit out by AR2987's remnants. Strong geomagnetic storms were also observed on Sunday (April 10) (opens in new tab).
The number of sunspots during this cycle is on the upswing and is expected to peak in 2025 (opens in new tab), which means more opportunities for solar storms - and auroras. The sun is currently in Solar Cycle 25, the 25th since formal observations began in 1755. It's a time of increased activity for our nearest star, which goes through periods of quiet and activity known as solar cycles. The aurora may become visible at lower latitudes than usual, as far south as northern Michigan and Maine.Īll of this activity is fairly par for the course for the sun, according to the Solar Influences Data Analysis Center, part of the Royal Observatory of Belgium. The CME released Monday might yield a minor (G1) geomagnetic storm on April 14, meaning that there could be minor impacts on satellite operations and weak fluctuations in the power grid, according to SpaceWeather. 9 Ideas about black holes that will blow your mind (opens in new tab) The 12 strangest objects in the universe (opens in new tab)
15 Unforgettable images of stars (opens in new tab) The idea of a "dead" sunspot is more poetic than scientific, said Philip Judge, a solar physicist at the High Altitude Observatory at the National Center for Atmospheric Research (NCAR), but the convection of the sun breaks these spots apart, leaving in their wake magnetically-disturbed bits of quiet solar surface. These spots are temporary and can last anywhere from hours to months. They are caused by intense magnetic flux from the sun's interior, according to the Space Weather Prediction Center (opens in new tab). 14, 2021, NASA announced that the spacecraft has plunged through the unexplored solar atmosphere known as the corona in April, and will keep drawing ever closer to the sun and diving deeper into the corona. Sunspots are dark regions on the surface of the sun. FILE - This image made available by NASA shows an artist's rendering of the Parker Solar Probe approaching the Sun.
The material in that CME is likely to impact Earth on April 14, according to SpaceWeather. The sunspot explosion released loads of energy in the form of radiation, which also led to a coronal mass ejection (CME) - explosive balls of solar material - both of which could spur more intense northern lights in Earth's upper atmosphere. The sun explosion comes courtesy of a dead sunspot called AR2987, according to (opens in new tab).
