Weekly Forecast

During the past 24 hours, solar activity was very low. Five active sunspot regions were on the visible disk without C-class and above flares produced. The solar wind speed decreased to about 270 km/s. The geomagnetic field was quiet.

Within the next three days, solar activity is expected to be mainly low with a slight chance for M-class flares. The geomagnetic field is expected to be mainly at quiet to unsettled levels with isolated active levels on 8 Aug.

During the last week, solar activity was low. Ten sunspot active regions (AR4492, AR4494-AR4496, AR4498-AR4503) were on the visible disk without M-class or above flare produced. SEP ended on 31 Jul and the maximum proton flux reached 18.1 pfu. The F10.7 index decreased from 148 sfu to 101 sfu. Due to the effect of CME on 30 Jul, the geomagnetic field reached moderate storm levels for 3 hours and active levels for 18 hours on 2-4 Aug. It was quiet to unsettled for the rest of the time.

Within the next week, solar activity is expected to be low to moderate with chances for M-class flares. The geomagnetic field is expected to be mainly quiet to unsettled with isolated active levels on 8 Aug and 11 Aug due to the effect of a recurrent coronal hole high speed stream.

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.
