| During the last week, solar activity was extremely high on 1 Feb, high on 2-5 Feb and low for the rest of the time. Fifteen active sunspot regions (AR4349, AR4357-AR4360, AR4362-AR4363, AR4365-AR4372) were on the visible disk with 6 X-class and 61 M-Class flares produced. No solar proton event occured. The F10.7 index ranged from 128 sfu to 178 sfu. Due to the continuous effect of the recurrent coronal hole high speed stream, the geomagnetic field reached active levels for 3 hours on 30 Jan. Due to the arrival of the CME which associated with X8.1 flare on 2 Feb, the solar wind speed reached a peak value of 610 km/s, and the geomagnetic field reached minor storm levels for 6 hours and active levels for 9 hours on 4-5 Feb. The geomagnetic field was quiet to unsettled on the rest of the time. The greater than 2 MeV electron flux at geosynchronous orbit maintained at minor storm levels during 30 Jan - 4 Feb. | |
| Within the next week, solar activity is expected to be mainly moderate with chances for M-class and above flares. The geomagnetic field is expected to reach isolated active levels on 6-7 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. | | Published: 2026-02-06 06:30 UTC Forecaster: 027/026 |

| 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. | | Published: 2026-02-13 06:30 UTC Forecaster: 027/022 |

| During the last week, solar activity was low to moderate, moderate on 13, 16 Feb and low for the rest of time. Six active sunspot regions (AR4369, AR4373-AR4377) were on the visible disk with two M-Class flares produced. No solar proton event occured. The F10.7 index ranged from 116 sfu to 122 sfu. The solar wind speed increased to 420km/s and the geomagnetic field was at active levels for 6 hours. Due to the effect of the recurrent coronal hole high speed stream, the solar wind speed reached the peak of 700km/s and the geomagnetic field was at moderate storm levels for 3 hours, minor storm levesl for 6 hours, active levels for 18 hours on 14-16 Feb. It was quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 18,19 Feb. | |
| Within the next week, solar activity is expected to be mainly low with little chances for M-class flares. The geomagnetic field is expected to reach active to minor storm levels on 24-26 Feb due to the effect of the recurrent coronal hole high speed stream. It will be mainly quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit will remain at minor storm levels on 20-22 Feb. | | Published: 2026-02-20 06:30 UTC Forecaster: 010 |

| During the last week, solar activity was moderate on 25 Feb, very low on 21 Feb and 23 Feb, and low on the rest of the time. Six active sunspot regions (AR4374-AR4375, AR4377-AR4380) were on the visible disk with one M-Class flare produced. No solar proton event occured. The F10.7 index ranged from 108 sfu to 130 sfu. Due to the effect of the CME on 16 Feb, the geomagnetic field was at active levels for 6 hours on 20-21 Feb. Due to the effect of the recurrent coronal hole high speed stream, the solar wind speed reached to a peak value of 720 km/s and the geomagnetic field was at minor storm levels for 12 hours, and active levels for 48 hours on 21-26 Feb. It was quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 20, 23-26 Feb. | |
| Within the next week, solar activity is expected to be mainly low to moderate with chances for M-class flares. The geomagnetic field is expected to be mainly quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit will remain at minor storm levels on 27 Feb-1 Mar. | | Published: 2026-02-27 06:30 UTC Forecaster: 041/012 |

| During the last week, solar activity was low. Nine active sunspot regions (AR4378-AR4386) were on the visible disk without M-Class flare produced. No solar proton event occured. The F10.7 index ranged from 139 sfu to 148 sfu. The solar wind speed reached a peak value of 440 km/s and the geomagnetic field was at minor storm levels for 3 hours on 3 Mar. It was quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 27 Feb to 2 Mar. | |
| Within the next week, solar activity is expected to be mainly low with chances for M-class flares. Due to the effect of the recurrent coronal hole high speed streams, the geomagnetic field is expected to reach isolated active or minor storm periods during 6-9 Mar. It will be mainly quiet to unsettled for the rest of time. | | Published: 2026-03-06 06:30 UTC Forecaster: 010/042 |
