NOAA: Largest Solar Radiation Storm Since 2005 Now in Progress

NOAA: Largest Solar Radiation Storm Since 2005 Now in Progress:

Earth’s magnetic field is already full of activity from an Earth-directed Coronal Mass Ejection (CME) last week. But all indications are another blast is headed our way from the strongest solar radiation storm since September, 2005. NOAA says the storm is currently in progress and continues to get stronger, with a very fast CME headed towards Earth. Sunspot 1402 erupted, producing a long-duration M9-class solar flare. “Geomagnetic storming is a near certainty from this event,” reported NOAA. The associated solar flare peaked at about 0400 UTC on January 23 (11pm Jan 22 EST).”

A computer model just released by NOAA’s Space Weather Prediction Center forecasts the storm will arrive sometime on January 24, at about 14:18 UT (+/- 7 hours), as the CME is traveling at approx. 2,200 km per second. Click here to see the animated model.

We’ve already shown you a video of the auroral activity going on yesterday and will soon post a gallery of beautiful aurorae from around the world. And it looks like we’ll likely have more photos to share in the coming week! And NASA says skywatchers should be on the lookout for aurora in lower than normal latitudes. Scientists are also predicting that Mars will get hit too, several hours after Earth. At this point, there’s no way to predict the possible effect on Earth-orbiting satellites for communications, GPS, etc, or the effect on Mars spacecraft.

These kinds of events can cause problems for spacecrafts in geosynchronous, polar and other orbits passing could be affected by the cloud’s arrival. In addition, strong geomagnetic storms are possible, so high-latitude sky watchers should be alert for aurorae.

Below is a video from the Solar Dynamics Observatory of the event:

NASA Photos Photography

The National Aeronautics and Space Administration (NASA) is the United States government agency responsible for the civilian space program as well as aeronautics and aerospace research. President Dwight D. Eisenhower established the National Aeronautics and Space Administration (NASA) in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.

UFO SIGHTINGS PHOTO PHOTOGRAPHY

The Oxford English Dictionary defines a UFO as "An unidentified flying object; a 'flying saucer'." The first published book to use the word was authored by Donald E. Keyhoe. The acronym "UFO" was coined by Captain Edward J. Ruppelt, who headed Project Blue Book, then the USAF's official investigation of UFOs. He wrote, "Obviously the term 'flying saucer' is misleading when applied to objects of every conceivable shape and performance. For this reason the military prefers the more general, if less colorful, name: unidentified flying objects. UFO (pronounced Yoo-foe) for short." Other phrases that were used officially and that predate the UFO acronym include "flying flapjack", "flying disc", "unexplained flying discs", "unidentifiable object", and "flying saucer". The phrase "flying saucer" had gained widespread attention after the summer of 1947. On June 24, a civilian pilot named Kenneth Arnold reported seeing nine objects flying in formation near Mount Rainier. Arnold timed the sighting and estimated the speed of discs to be over 1,200 mph (1,931 km/h). At the time, he described the objects' shape as being somewhat disc-like or saucer-like, leading to newspaper accounts of "flying saucers" and "flying discs". In popular usage the term UFO came to be used to refer to claims of alien spacecraft. and because of the public and media ridicule associated with the topic, some investigators prefer to use such terms as unidentified aerial phenomenon (or UAP) or anomalous phenomena, as in the title of the National Aviation Reporting Center on Anomalous Phenomena (NARCAP).

UFO - Unidentified Flying Object An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon. Culturally, UFOs are associated with claims of visitation by extraterrestrial life or government-related conspiracy theories, and have become popular subjects in fiction. While UFOs are often later identified, sometimes identification may not be possible owing to the usually low quality of evidence related to UFO sightings (generally anecdotal evidence and eyewitness accounts). Stories of fantastical celestial apparitions have been told since antiquity, but the term "UFO" (or "UFOB") was officially created in 1953 by the United States Air Force (USAF) to serve as a catch-all for all such reports. In its initial definition, the USAF stated that a "UFOB" was "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." Accordingly, the term was initially restricted to that fraction of cases which remained unidentified after investigation, as the USAF was interested in potential national security reasons and/or "technical aspects" (see Air Force Regulation 200-2). During the late 1940s and through the 1950s, UFOs were often referred to popularly as "flying saucers" or "flying discs". The term UFO became more widespread during the 1950s, at first in technical literature, but later in popular use. UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security. Various studies have concluded that the phenomenon does not represent a threat to national security nor does it contain anything worthy of scientific pursuit (e.g., 1951 Flying Saucer Working Party, 1953 CIA Robertson Panel, USAF Project Blue Book, Condon Committee).
