Weekly Forecast

During the past 24 hours, solar activity was low. There were 3 active sunspot regions on the visble disk without M-class and above flares produced. The solar wind speed decreased to about 450 km/s, the geomagnetic field was quiet to unsettled.

Within the next three days, solar activity is expected to be low to moderate with chances for M-class flares. Due to the effects of the recurrent coronal hole high speed stream and the CME from 16 Feb, the geomagnetic field is expected to reach isolated active levels on 19 Feb and mainly quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit will reach minor storm level on 18-21 Feb.

During the last week, solar activity was low to moderate, moderate on 8-12 Feb and low for the rest of the time. Eleven active sunspot regions (AR4358, AR4362, AR4366-AR4371, AR4373-AR4375) were on the visible disk with 8 M-Class flares produced. No solar proton event occured. The F10.7 index decreased from 169 sfu to 129 sfu. Due to the continuous effect of the CME from 2 Feb, the geomagnetic field reached active levels for 15 hours on 6-7 Feb. The geomagnetic field reached active levels for 9 hours on 10-11 Feb. It was quiet to unsettled for the rest of the time.

Within the next week, solar activity is expected to be mainly low with chances for M-class flares. The geomagnetic field is expected to reach isolated active or minor storm levels on 14-16 Feb due to the effect of the recurrent coronal hole high speed stream. It will be mainly quiet to unsettled for the rest of the time.

LATEST DATA



		The magnetic map of the activity area is generated based on the full day longitudinal magnetic field data of the Huairou Solar Observatory in Beijing.				This full-disk Hα image of sun is observed with the 20cm Full-Disc Hα Telescope located at Huairou Solar Observatory Station of Beijing in China.



		Observatories of cosmic ray in SEPC include Beijing station monitoring Neutron intensity variations and Guangzhou station monitoring the intensity variations of East, West, South, North and Vertical components of muon.				This model is an improved geomagnetic K-index current reporting model based on the evaluation of Takahashi, a commonly used international Kp index current reporting model, and its application to Chinese geomagnetic stations.
