1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 01.07.2019 at 20:00 UTC was 68 sfu.
The background X-Ray flux is at the class A7 level.
The geomagnetic field was at quiet to unsettled levels on July 1.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at almost quiet levels with Kp=2.

2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 365 km/s.
Solar Wind speed from STEREO A: 380 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 2 nT south.

3. Solar Energetic Particle Events
Protons and electrons are quiet.

4. Coronal Holes
A new equatorial coronal hole (CH927) will be in Earth facing position on July 1-2. A high speed stream of solar wind from this CH is expected to reach Earth on the first half of July 5.

5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on July 2-4 with a chance for unsettled intervals.
