EA, SPAIN. Plans are for team EG5MI to reach Penyeta del Moro (EU-151) on May 24th in the afternoon. They will place a wooden platform on the rocks, followed by a first station (15m CW) and hopefully a second station (20m FT8 around 14087 kHz). They will QRT soon after sunset (1915 UTC). On May 25th, soon after sunrise (0441 UTC), they will return to the islet and, if the platform is still there - they will set up the CW station (first on 17m and later QSY to 12m) and hopefully the FT8 station (first on 20m and later on 15m around 21087 kHz). EG5MI will operate also SSB, "bands and times will be decided on the spot". They will QRT when the batteries die, possibly by 1100 UTC. A "less optimistic scenario" involves activating only one station at a time, having to choose the mode subject to best rates. "The good news is that in such case our time on air would be longer", EA3NT says. Check out https://www.youtube.com/@EA3NT for live coverage of the sailing, the landing and the set up on the islet, and probably even the first QSOs being worked. QSL via EA5GL.

Solar Data

The Weekly Solar Data chart plots Solar Flux Index (SFI), Sunspot number (SSN) and Planetary K-Index (Kp) 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 Saturday, May 18th through yesterday, May 25th.

The average solar flux was 183, down 28 points from the previous week, with a weekly high of 201 on Sunday, May 19th, followed by a low of 152 on May 25th.

The average sunspot count was 126, down by 59 from last week, peaking at 166 on Saturday, May 18th followed by a weekly low of 100 on May 24th.

The Planetary K-index weekly average was 3.0 with a maximum of 4.0 on Thursday, May 23rd, resulting in generally quiet geomagnetic conditions. Yesterday's K-index maximum was 2.7, producing generally quiet geomagnetic conditions.

Solar flare activity since May 19th has been high with 14 major flares, the largest of which was an M 4.2 event on Thursday, May 23rd.

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!
