1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 29.09.2023 at 20:00 UTC was 155 sfu.
The background X-Ray flux is at the class A0.0 level.
The geomagnetic field was at quiet to active levels on September 29.
No obviously Earth directed CMEs were observed in available LASCO imagery.
The Kp index now is at quiet levels with Kp=2.
2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 453 km/s.
Solar Wind speed from STEREO A: 400 km/s.
Solar Wind speed from STEREO B: - km/s.
The southward component Bz is: 5 nT south.
3. Solar Energetic Particle Events
Protons and electrons are quiet.
4. Coronal Holes
No obvious coronal holes are currently in the visible solar disk.
5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on September 30-October 02.
Date Estimated Ap index Expected geom. storm
