Weekly Forecast

During the past 24 hours, solar activity was moderate. Five active sunspot regions were on the visible disk with one M-class flare produced. The solar wind speed maintained at about 400km/s, and the geomagnetic field was at quiet to unsettled levels.

Within the next three days, solar activity is expected to be moderate with chances for M-class and above flares. The geomagnetic field is expected to reach active to minor storm levels on 9-10 Jul due to the effect of the recurrent coronal hole high speed stream. It will be mainly quiet to unsettled for the rest of time.

During the last week, solar activity was high on 30 Jun and 1 Jul, moderate on 29 Jun and 2 Jul, low for the rest of time. Six sunspot active regions (AR4475-AR4480) were on the visible disk with one X1.1 flare and seventeen M-Class flares produced. No solar proton event occurred. The F10.7 index increased from 163 sfu to 203 sfu. Due to the effect of CME from 26 Jun, the solar wind speed reached a peak of about 430 km/s. Due and the geomagnetic field was at minor storm level for 6 hours, active levels for 6 hours during 30 Jun-1 Jul. It was quiet to unsettled for the rest of the time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 27-30 Jun.

Within the next week, solar activity is expected to be mainly moderate with a chance for M-class or above flares. The geomagnetic field is expected to reach storm levels on 3-4 Jul due to the effects of the CME from 30 Jun, and reach active to minor storm levels on 8-9 Jul due to the recurrent coronal hole high speed streams. It will be 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.
