I cannot remember the supposed link between Es and thunderstorms (something to do with sprites going upwards from thunder clouds?) but with plenty of thunderstorms in the Alps, I wonder how Es will be tomorrow? Maybe conditions to southern Europe will be good on 6m Es?
Although I probably could safely reconnect antennas this evening now the storms have passed, I think it will be better to wait until the morning.
Knowing my luck, the 6m band will open transatlantic tonight and I shall miss it all! That would not be the end of the world.
It is now 2015z and on 10m the Es keeps on coming. This is a good, solid and widespread Es opening.
|Recent 10m WSPR spots this evening|
UPDATE 2110z: 10m Es still going strong a few minutes ago.
UPDATE 2145z: Es seemed to have stopped (here) at about 2100z. Oh no it didn’t! IK1WVQ was spotted at 2134z and 2142z.. HB9JOI spotted me at 2138z. The Es is still going strong.
UPDATE 2220z: Although Es has been good on 10m all day and F2 was good to FR1GZ earlier, there has been no F2 to South America on 10m WSPR at least not yet. This was surprising. EB3EPR is still spotting me at 2218z.
UPDATE 2232z: Bed time, but 10m WSPR still running overnight, unless the PC does an update and closes the software again!
As teatime continues, yet more Es 10m propagation is evident.
DC3RJ (817km) is the latest who spotted me at 1754z. Earlier EB3EPR (1248km) spotted me twice. Now EA1KV (1304km) and DK6UG are spotting me at 1806z.
Some weeks ago I was questioning the propagation to a GM reporter on 6m, but realise now the distance is comparable with parts of Germany, so an easy Es single hop.
UPDATE 1840Z: HB3YHB (793km) was spotted at 1838z on 10m WSPR.
During the afternoon G4FFC (45km) and M0BOB (74km) were both copied on 10m WSPR. These are both outside local range and I would class these as GDX (just). Both show some Doppler so may be helped by aircraft reflection.
On F2 FR1GZ (9724km, Reunion Is) was being copied until 1512z, so good F2 propagation. I wonder if we’ll see South Americans later?
Es disappeared (here) at 1404z but may return this teatime.
UPDATE 1740z: EB3EPR (1248km) spotted me at 1736z and 1746z so Es is back (it is teatime!).
FR1GZ (9734km, on Reunion Is, south Indian Ocean) is still coming through here on 10m WSPR at -27dB S/N at 1444z and again at 1504z at -25dB S/N. F2 propagation N-S is still there when HF conditions are good.
Sunspot count today is “only” 80 – a year from now this will sound amazingly high – although 20-30MHz conditions are forecast to be “good”.
F2 on 6m is very rare except at high sunspot peaks and in latitudes nearer the equator. TEP involving F2 over the equator is more common, but it requires stations to be in the right places to work. On 6m the paths from CN8 to FR1 were open by TEP this spring. Also 4X to FR1 and VK to JA.
On 10m TEP should be more frequent. Sometimes F2 links with Es further from the equator, allowing TEP to be extended to stations in higher latitudes.
On 10m G4DAY (142km) was copied twice in the early morning and again at 0940z.
Es has been plentiful this morning. Looking at the WSPR screen earlier there was lots of MS about with several traces of intermittent (non decoding) signals on 10m WSPR, presumably UK or EU signals reflecting off meteor trails. Es so far includes DL6UG, DL6NL, EB3EPR, EA5CYA, LB9YE and HB9JOI.
Also spotted FR1GZ (9724km) by F2 propagation at 1038z, 1122z and again at 1128z.
10m is a far more productive band than 6m. Interestingly, G4DAY (10W) was being spotted by Es several times in the night suggesting Es propagation was there but not good enough to allow my 2W to be decoded. For some Es and GDX it seems 10W helps.
