I. Solar activity--Current StatusSolar Flux (10.7cm) measured on 30.03.2025 at 23:00 UTC was 171 sfu.
The background X-Ray flux is at the class C5.0 level.
Five M-class solar flares were produced on March 30.
No obviously Earth directed CMEs were observed in available LASCO imagery on March 27-29.
A large coronal hole (CH1279) at southern hemisphere will be Earth facing on March 21-26.
II. Solar Energetic Particle EventsProtons fluxes are quiet.
The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm level.
III. Interplanetary and Geomagnetic conditionsThe solar wind speed measured by ACE satellite reached the max value 475 Km/s on March 30 at 04:35 UT during the last 24 hours.
The solar wind speed from STEREO A was detected 400 Km/s during the last 24 hours.
The vertical component of IMF Bz reached the max value -5 nT on March 30 at 06:55 UT during the last 24 hours.
The geomagnetic field was at quiet to unsettled levels during the last 24 hours.
The Kp index now is at quiet levels with Kp=1.
IV. 3-day Geomagnetic Activity ForecastThe geomagnetic field is expected to be at quiet to unsettled levels on March 31-April 02.
