On Feb. 13th at 1738 UT, sunspot 1158 unleashed the strongest solar flare of the year so far, an X-ray irradiance magnitude.
The biggest sunspot on the face of the sun in more than two decades unleashed a major flare on Friday (Oct. 24), the fourth intense solar storm.
Below you'll find an overview of the solar flares that occurred on the Sun today, arranged in order of time of occurrence. If there weren't any noteworthy events on.
Sunspot flare - puzzles
For example, magnetically complex regions based on line-of-sight magnetic field called delta spots produce the largest flares. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. The same energy releases may produce coronal mass ejections CME , although the relation between CMEs and flares is still not well established. Direct radio emission at decimetric wavelengths may disturb the operation of radars and other devices that use those frequencies. Regions due to return. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay.

Center. For example, magnetically complex regions based on line-of-sight magnetic field called delta spots produce the largest flares. Sunspots are dark areas on the surface of the sun that are slightly cooler than surrounding regions. Forecasts looking ahead more than a few days are often wrong.
