Weekly Forecast

During the past 24 hours, solar activity was low. Eight sunspot active regions were on the visible disk without M-class and above flare produced. The solar wind speed decreased to about 430 km/s. The geomagnetic field was at quiet to unsettled levels.

Within the next three days, solar activity is expected to be low to moderate with chances for M-class flares. Due to the effect of the CME from 6 Jun, the geomagnetic field is expected to reach minor storm levels on 9 Jun. It is expected to be mainly quiet to unsettled with isolated periods for active levels during 10-11 Jun.

During the last week, solar activity was high on 3 Jun, moderate on 29 May and 2 Jun, and low on the other days. Fourteen sunspot active regions (AR4444, AR4446-AR4447, AR4449, AR4452, AR4454-AR4462) were on the visible disk with one X1.0 and six M-class flares produced. No solar proton event occurred. The F10.7 index ranged from 132 sfu to 148 sfu. Due to the effect of a recurrent coronal hole high speed stream, the solar wind speed reached a peak value of about 550km/s, and the geomagnetic field was at active levels for 12 hours on 29-31 May. 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 a chance for M-class flares. Due to the effects of multiple CMEs on 3 Jun, the geomagnetic field is expected to reach storm levels on 5-6 Jun. It is expected to 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.
