Propagation (Updated daily)

Solar Data

The Weekly Solar Data chart plots Solar Flux Index (SFI), Sunspot number (SSN) and Planetary K-Index (K-Idx) for the past 8 days. With 8 Planetary K-index readings each day, only the minimum, average and maximum K-index values are plotted. Note: You may click here or on the chart above to see the same data for the past month.

The Daily Solar Flux Index, Sunspot number, Planetary K-index, Solar Flux predictions and Solar Flare data used in this bulletin have been collected by KØCF from from the U.S. Department of Commerce's NOAA Space Weather Prediction Center.

The propagation graphs above are the creations of KØCF and are unique in space weather reporting.

Propagation Summary
For the 8 day period from Thursday, February 15th through yesterday, February 22nd.

The average solar flux was 163, down 25 points from the previous week, with a weekly high of 178 on Thursday, February 15th, followed by a low of 152 on February 19th.

The average sunspot count was 69, down by 65 from last week, peaking at 151 on Thursday, February 15th followed by a weekly low of 45 on February 21st.

The Planetary K-index weekly average was 2.2 with a maximum of 3.3 on Sunday, February 18th, resulting in generally quiet geomagnetic conditions.

Solar flare activity since February 15th has been high with 10 major flares, the largest of which was a major X 6.3 event on Thursday, February 22nd.

Another Major Solar Flare
Earth-orbiting satellites have just detected an X6.3-class solar flare from sunspot AR3590 (Feb. 22 @ 2234 UT). This is the strongest flare of Solar Cycle 25, and the third X-flare the sunspot has produced in a 24 hour period. Stay tuned for updates about this explosion, especially whether or not it has hurled a CME toward Earth.

Double X-Class Solar Flare (Updated)
Big sunspot AR3590 is as dangerous as it looks. Late yesterday (Feb. 21 @ 2307 UT), the active region produced a powerful X1.8-class solar flare with a shortwave radio blackout over the western USA and Pacific Ocean. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:

Double X-Flares

Hours later (Feb. 22 @ 0635), the sunspot erupted again, producing an almost identical X1.7-class flare. Neither explosion produced a bright CME. This means the double flares will *not* cause a geomagnetic storm on Earth.

More explosions are in the offing. AR3590 has an unstable 'beta-gamma-delta' magnetic field that harbors energy for additional X-class explosions.

Cycle 25 vs. Past Cycles
Propagation guru Carl Luetzelschwab, K9LA has created this graph showing Cycle 25 progress as compared to a few past Solar Cycles. It is very interesting to see that Cycle 25 is a very modest iteration, providing some good but not great propagation on the HF bands.

A Propagation Tutorial
The solar X-ray flux tracks solar activity and solar flares. Solar flux, which can vary from as low as 50 to as high as 300, influences the level of ionization in the F2 region of the ionosphere, providing a very good prediction of HF DX conditions. The higher the solar flux, the better conditions will be for the higher HF frequencies and even 6 meters. However, the levels need to be maintained for some days to allow ionization in the F2 layer to build up. A solar flux of 150 results in good HF band conditions, while levels of 200 and up can provide great conditions.

Large X-ray flares on the sun can increase the ionization of the D layer of the ionosphere (a lower layer) on the sunlit side of the Earth, greatly attenuating or blocking HF radio transmissions for up to a half hour. Solar flares often produce Coronal Mass Ejections (CMEs) which, if Earth directed, can lead to geomagnetic storms. Some large flares are also accompanied by strong radio bursts that may interfere with other radio frequencies and cause problems for satellite communication and radio navigation (GPS).

The Planetary K-index is a measure of the magnitude of geomagnetic storms and is an excellent indicator of disturbances in the Earth's magnetic field. A level of 1 or 2 represents quiet geomagnetic conditions; a reading of 3 or 4 may cause some propagation deterioration; 5 and 6 are minor to moderate geomagnetic storms; and 7 to 9 are strong, severe, and extreme storm conditions. Strong geomagnetic storms can trigger Auroral displays and cause HF radio blackouts. Higher geomagnetic activity also has the adverse effect of lowering maximum usable frequencies, much like lower solar flux does.

For best conditions, the solar flux should be above 150 for a few days with the K index below 2. When these conditions are met, some good DX is likely!
