Näin kertoo SIDC tänään: Except for a small magnetic dipole just passing the East limb in Extreme-UV images (probably a plage without sunspots), the Sun is featureless and is expected to remain inactive. Since early today, the solar wind has virtually vanished, reaching exceptionally low speeds (now at 250 km/s), low densities (< 0.1 electron/cm3) and low plasma temperatures (< 10⁴ K), based on ACE and SOHO/MTOF data. This leads also to exceptionally quiet geomagnetic conditions (Kp=0 at many ground stations). Those extremely quiet conditions certainly deserve special study.
Eli aurinko on nyt niin hiljainen, että tarvitaan lisätutkimuksia selvittämään, mistä tämä johtuu. Miksei sitten mitään kuulu? Onko meillä huomenna enää aurinkoa?? Miten käy plussakeskustelulle, jos aurinko sammuu??? T: Jim
