What is geomagnetic K index?
The K-index quantifies disturbances in the horizontal component of earth’s magnetic field with an integer in the range 0-9 with 1 being calm and 5 or more indicating a geomagnetic storm. It is derived from the maximum fluctuations of horizontal components observed on a magnetometer during a three-hour interval.
Where is Space Weather Prediction Center?
The Space Weather Prediction Center (SWPC) is a laboratory and weather forecasting center of the National Oceanic and Atmospheric Administration (NOAA) located in Boulder, Colorado. SWPC continually monitors and forecasts Earth’s space environment, providing solar-terrestrial information.
What is a good solar flux index?
For best conditions, the solar flux should remain above about 150 for a few days with the K index below 2.
Are we in a solar minimum 2021?
It began in December 2019 with a smoothed minimum sunspot number of 1.8. It is expected to continue until about 2030….

What does KP 4 mean?
Active
Kp 4 – Active – Bright, constant and dynamic northern lights visible. More colours start to appear. Kp 5 – Minor storm – Bright, constant and colourful aurora display, red and purple colours appear. Aurora coronae likely. Kp 6 – Moderate storm – Bright, dynamic and colourful aurora display.
How do you read the Kp index?
Kp-index
- Kp 0 – Quiet – Aurora oval mostly to the north of Iceland.
- Kp 1 – Quiet – Aurora oval over Iceland, faint and quiet aurorae visible to the unaided eye low in the northern sky.
- Kp 2 – Quiet – Auroras readily visible and become brighter and more dynamic.
- Kp 3 – Unsettled – Bright auroras visible at zenith.
How long does it take a solar flare to reach Earth?
8 minutes
The radiation emitted from solar flares travels at the speed of light and can reach Earth from the sun in just over 8 minutes.
How do you read the solar flux index?
Values between 0 and 1 represent quiet magnetic conditions and this would indicate good HF band conditions, subject to a suffi- cient level of solar flux. Values between 2 and 4 indicate unsettled or even active magnetic conditions, and are likely to be reflected in a degradation of HF condi- tions.
Are we overdue for a Carrington event?
Usually, we get lucky with these solar storms failing to collide with Earth, but scientists warn our good fortune won’t last forever and we’re long overdue an event of the magnitude of the so-called Carrington Event in 1859.
What is the intensity of a solar flare?
Solar flare intensities cover a large range and are classified in terms of peak emission in the 0.1 – 0.8 nm spectral band (soft x-rays) of the NOAA/GOES XRS. The X-ray flux levels start with the “A” level (nominally starting at 10 -8 W/m 2 ).
What will be the sunspot number and radio flux in 2021?
Predicted Sunspot Number And Radio Flux Date Sunspot Number Predicted Sunspot Number High Sunspot Number Low 10.7 cm Radio Flux Predicted 2021-03 20.6 21.6 19.6 78.5 2021-04 21.6 23.6 19.6 78.8 2021-05 21.5 24.5 18.5 78.3 2021-06 21.2 26.2 16.2 77.5
What is the frequency of the 2800 MHz daily radio flux?
The microwave wavelength 2800 MHz daily radio flux correlates highly with the daily sunspot number and the two databases are used interchangeably. The 2800 MHz, or 10.7 cm, responds to the same conditions that produce changes in the visible and X-ray wavelengths.
What is the frequency range of solar radio waves?
The 2800 MHz, or 10.7 cm, responds to the same conditions that produce changes in the visible and X-ray wavelengths. Schmahl and Kundu (1995) find that the solar radio fluxes in the spectral range 1000-9400 MHz correlate well with the total solar irradiance.
