There were 3 flares with all of them are C-class flares in the last 24 hours. The maximum flare class was C1.1 from NOAA4366 peaked at 7:40UT. There were 2 solar radioburst all of which are type-III occurred in the last 24 hours. There was 4 CME event in the last 24 hours. The east-directed CME has the highest median velocity of 272 km/s with an angular width of 20 degrees and the west-directed CME has the highest median velocity of 428 km/s with an angular width of 30 degrees. The latest SDO/HMI Intensitygram data shows 7 active regions (NOAA4367,4368,4369,4371,4373,4374,4375) and the latest BBSO H-Alpha data shows 1 H-Alpha plages (NOAA4370).

Geomagnetic Activity

The geomagnetic activity was on quiet level for the last 24 hours.

The solar wind speed decrease from 363 km/s to 537 km/s, north-south component of interplanetary magnetic field fluctuate between -6.8 nT and 6.5 nT. There was geoeffective coronal hole at central equator, while the others at eastern equator, north-west and south-west were not geoeffective. CME on 12 February 2026 13:36 UT was mainly errupted toward south-west with speed of 428 km/s and angular width of 30°. The CME was geoeffective and is likely to have impact on 20 February 2026.

Ionospheric Activity

Evaluation of the ionospheric activity, foF2 value, the increase in the fmin value, Spread-F, and the Sporadic E-Layer cannot be reported due to problems at the CADI station. However the S4 index values (condition of ionospheric scintillation) was on quiet level (S4<0.5) for the last 24 hours over Pontianak. TEC index was on quiet level (VTEC<125) for the last 24 hours over Pontianak.
