Solar activity was very low with X-ray flux below C level and no flares observed. NOAA region 2581 grew slightly, while the other regions were in decay. X-ray flux is expected to remain below C level. Solar proton flux is at background levels and expected to remain so. No Earth directed CMEs have been observed in coronagraph data. A transequatorial positive polarity coronal hole is currently transiting the central meridian and is expected to become geoeffective on August 29.
Solar wind conditions were near nominal with solar wind speed currently around 425 km/s. Total magnetic field was steady around 5nT with a variable Bz component. The magnetic field phi angle indicates a negative sector throughout the period. Solar wind conditions are first expected to remain nominal with later tomorrow an expected boundary crossing ahead of the onset of a positive polarity coronal hole high speed stream.
Geomagnetic conditions were quiet to unsettled (both local K Dourbes and NOAA Kp 1-3) and expected to remain so the next 24 hours. Afterwards conditions are expected to rise to unsettled to active and later unsettled to minor storm levels with the expected sector change and high speed stream influence.
Today's estimated international sunspot number (ISN): 058, based on 18 stations.
