Solar Activity

24 hr Summary: Solar activity was very low under a spotless solar disk. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to be very low on 15-17 Jul.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 15-17 Jul. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were nominal.

Forecast: Solar wind parameters are expected to be slightly enhanced on 15-17 Jul.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (15-16 Jul) due to influence from a recurrent, negative polarity CH HSS. Day three (17 Jul) should be mostly quiet as CH HSS effects lessen.
