Detailed Information

Solar Activity

Solar activity over the past 24 hours was eruptive, characterized by four C-class flares. No M-class or X-class flares were observed. The strongest event was a C1.9 flare originating from NOAA 14383, which peaked at 7:12UT. Associated with this activity, no solar radio bursts were observed. One coronal mass ejection was detected, originating from the west limb with a speed of 310 kilometers per second and an angular width of 36 degrees. No east limb CME data was available.

On the visible disk, five active regions were identified by SDO/HMI: NOAA 14378, NOAA 14381, NOAA 14384, NOAA 14385, and NOAA 14386. Additionally, three H-alpha plages were noted by BBSO, corresponding to NOAA 14379, NOAA 14380, and NOAA 14383. Looking ahead, one region is due to return between 06 March and 08 March. 

The overall solar activity for
march 8th, 2026 04:00 UT - march 9th, 2026 03:59 UT is predicted to be eruptive,
march 9th, 2026 04:00 UT - march 10th, 2026 03:59 UT is predicted to be eruptive,
march 10th, 2026 04:00 UT - march 11th, 2026 03:59 UT is predicted to be eruptive,
with the Random Forest (RF) model forecasting a maximum flare class of C.

Geomagnetic Activity

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

The solar wind speed decrease from 473 km/s to 362 km/s, north-south component of interplanetary magnetic field fluctuate between -6.6 nT and 7.7 nT. There was geoeffective coronal hole at central equator, while the others at north-east and south-west were not geoeffective. CME on 05 March 2026 18:36 UT was mainly errupted toward west with speed of 310 km/s and angular width of 36°. The CME was geoeffective and is likely to have not impact until next 3 days.

Quiet level geomagnetic activity is expected for the next 24 hours.
Quiet level geomagnetic activity is expected for 07 March 2026 04UT - 08 March 2026 04UT.
Quiet level geomagnetic activity is expected for 08 March 2026 04UT - 09 March 2026 04UT.

Ionospheric Activity

Ionosphere was on quiet level for the last 24 hours.

There was no depression of foF2 lower than 30% of its median value. There was 45 minutes increment of fmin more than 30% of its median values. The Spread-F was detected for 510 minutes for the last 24 hours. There was 735 minutes Sporadic-E occurred in the night and daytime with foEs value exceeded the foF2 for several times. The S4 index values (condition of ionospheric scintillation ) was less than 0.8 (moderate) and the maximum TEC index value was at 95.42, both over Pontianak.

The ionosphere activity for the next 24 hours is predicted to be quiet.
The ionosphere activity for 07 March 2026 04.00UT - 08 March 2026 03.59UT is predicted to be quiet.
