Searchable data on this website include: GOES and ACE Satellite data, Kp and local K index and various local ground based observation data.
Graphs of 5-minute solar x-ray flux values measured on the GOES satellite.
Graphs of 5-minute proton flux values measured on the GOES satellite.
Graphs of 5-minute electron flux values measured on the GOES satellite.
The K-index ranges from 1 to 9. The K-index is calculated during a 3-hour interval based on the average values observed from various regions of the Earth. K-indices from Icheon, Gangneung and Jeju stations in South Korea are also available.
The variations in the geomagnetic field measured by GOES satellites (the horizontal components of the Earth’s rotation axis, Hp) are averaged every minute. The nanoTelsa is used as the unit of measurement.
Solar radio emissions provide one day values of the absolute solar flux in the wavelength bands of 30MHz-2.5GHz, as measured by the Icheon station of RRA.
Yesterday and today’s values of absolute solar flux in the wavelength bands, as measured in five different solar radio observatories around the world, are shown.
A total of 12 different types of solar images in various wavelength bands are displayed. Some of the solar images are observed by extreme ultraviolet and include the solar corona, solar white light and solar magnetic field distribution.
K-indices are calculated based on D and H components by using the magnetometers in Icheon, Gangneung and Jeju stations.
The values of the TEC (Total Electron Content) in the ionosphere observed in Icheon and Jeju stations are displayed. The values might temporarily fluctuate due to solar activity or geomagnetic storms.
