Also active will be seven memorial stations from the regions along whose coasts Gerasimov had imagined it would be possible to reach Asia: R5ØØO (Arkhangelsk Oblast), R5ØØM (Murmansk Oblast), R5ØØX (Komi Republic), R5ØØK (Yamalo-Nenets Autonomous Okrug), R5ØØZ (Kamchatka Krai), R5ØØF (Sakhalin Oblast), R5ØØL (Primorsky Krai). Gerasimov's geographical hypothesis was recorded by the Italian humanist Paolo Giovio in 1525. See https://hamlog.online/club/srr/1604/ for the certificate. All QSOs will be confirmed automatically via the bureau. QSL manager for all stations is RN3RQ.

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 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.

A Large Hole In The Sun's Atmosphere
A hole has opened in the sun's atmosphere, and it is spewing a stream of solar wind toward Earth. NASA's Solar Dynamics Observatory photographed the 300,000-wide butterfly-shaped gap on Sept. 11th:

This is a "coronal hole" -- a region in the sun's atmosphere where magnetic fields open up and allow solar wind to escape. Coronal holes look dark because hot plasma normally contained there is missing. It's on its way to us.
   A stream of solar wind flowing from this coronal hole should reach Earth on Sept. 14th. Its arrival could spark G1 to G2-class geomagnetic storms. The odds of storming are increased by the "Russell-McPherron effect," which links the magnetic fields of the sun and Earth during weeks around equinoxes.

Global D Region Absorption
Conditions in the D-region of the ionosphere have a dramatic effect on HF communications. The D-Region Absorption map combines the effects of solar particles and photons. Yellow to red colors on the map depict increasing signal attenuation, where the bar chart at the right displays attenuation versus frequency. Click the thumbnail below for an animated map of D-Region Absorption:
Absorption

The Aurora Borealis
The aurora is not only beautiful to see but can have a profound impact on HF and VHF radio propagation. For the HF operator, auroras can result in a complete shut-down of propagation. However, on VHF, auroras present interesting DX possibilities. Beam antennas are very desirable and should be pointed north, towards the aurora. Signals are reflected by “back-scatter” and will be distorted with a rough buzz. SSB is the best voice mode to use, but copy can be difficult. CW will have a rough buzzy sound but be perfectly copyable. Click the thumbnail below for an animated map of aurora versus time:

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!
