Bulletin

The Sun produced no C flares during the past 24 hours. B flaring is expected, with a chance for a C flare. During the past 24 hours, solar wind speed further decreased from about 400 to 340 km/s, while the magnitude of the Interplanetary Magnetic Field varied between about 1 and 4 nT. Bz was never below -4 nT for an extended period. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 0 and 2). Quiet geomagnetic conditions (K Dourbes < 3) are expected on July 18 and 19. Quiet to unsettled levels with active (K Dourbes = 4) excursions are possible on July 20 due to the expected arrival of a coronal hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 062, gebaseerd op 20 stations.
