公告

A new region near the East limb produced a C1.2 flare peaking at 12:10 UT on July 14. B flaring is expected, with a chance for a C flare. During the past 24 hours, solar wind speed gradually increased from about 450 to 520 km/s, while the magnitude of the Interplanetary Magnetic Field varied between about 7 and 10 nT. Bz was mostly positive throughout the period. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 1 and 3; NOAA Kp between 1 and 2). Quiet to active geomagnetic conditions (K Dourbes < 5) with possible minor storm excursions (K Dourbes = 5) are expected on July 15. Quiet to unsettled conditions (K Dourbes < 4) are likely on July 16 and 17.
