Solar flaring activity was at low levels over the past 24 hours. The largest flare observed was an C6.5 flare, peaking at 17 July 12:27 UT, originating from NOAA AR 3058. The flaring activity is expected to be at low levels with C-class flares expected, M-class flares are possible and there is chance for an X-class flare.
No significant Earth-directed coronal mass ejections have been observed over the past 24 hours.
The greater than 10 MeV proton flux was at nominal levels in the past 24 hours. The proton flux is mostly expected to remain at nominal levels for the next 24 hours. The greater than 2MeV electron flux dropped below the 1000 pfu threshold on 18 June 06:00UT. It is expected be about threshold over the next 24 hours. The 24h electron fluence was at moderate levels and is expected to be at moderate levels over the next 24 hours.
The solar wind speed had a slow decrease to around 400 km/s. The total magnetic field was mostly stable, reaching 8 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). A negative polarity southern coronal hole is currently at central meridian. A negative polarity northern coronal hole will be at central meridian tomorrow. Their high speed streams (HSS) can be expected 21-22 of July. A possible small effect from a HSS associated with the coronal hole at central meridian on 15 June cannot be excluded. In addition, possible impact from the CME associated with a filament eruption on July 15, expected late 19 July, may also be reflected in the solar wind parameters.
Geomagnetic conditions were quiet to unsettled over the past 24 hours (K Dourbes 3). Geomagnetic conditions are expected to be quiet to unsettled over the next 24 hours.
Today's estimated international sunspot number (ISN): 128, based on 28 stations.
