3000km Sporadic-E opening on 144 MHz from the Azores to Germany - 3rd June
2021

Posted: 04 Jun 2021 12:22 AM PDT https://ei7gl.blogspot.com/2021/06/3000km-sporadic-e-opening-on-144-mhz.html



Thursday 3rd June 2021: There was a remarkable opening on the 3rd of June
from the Azores in the North Atlantic to Europe with paths in excess of 3,000kms being recorded.
The FT8 map above from the PSK Reporter website for CU3EQ in the Azores
with a cluster of reports out around the 3000km mark in Belgium, the Netherlands and Germany. A full list of stations is shown at the bottom of
this post.
This is the map for CU3AA which has a similar pattern...

And this is the map for CU1AL...

For all three CU stations, paths in excess of 3000kms were open to Germany
on 144 MHz.
Propagation Mode: As reported by stations on the DX Cluster, the primary propagation mode was Sporadic-E. However as the maximum range for one hop
is in the region of 2300kms, something else had to make up the additional
700 or so kms.
There are two possibilities.
One was Chordal Hop Sp-E with a bounce going from Sp-E to Sp-E cloud. This would however require two intense areas of Sporadic-E at just the right
spot to support 144 MHz propagation.
The more likely scenario was that it was one Sporadic-E with a tropo
extension. The weather charts show high pressure over the Azores...

The tropo forecast from the website of Pascal, F5LEN suggests that a few hundred kms of tropo around the Azores might be possible.
The Sporadic-E prediction map from Jim, G3YLA shows a kink in the Jet
Stream to the south of Ireland which may have been a trigger mechanism for
the Sporadic-E.

In his daily E's prediction on the PropQuest website, G3YLA wrote... "The
sharp upper trough west of the UK is also a good source of atmospheric
gravity waves (AGW) and the southerly jet stream from Portugal to Ireland
could look good for paths to EA and CT with a possible extension by second
hop to EA8/D4."
This region is shown in Purple above and is very close to where the 144 MHz Sporadic-E cloud was located.
Conclusion: It seems likely that the first few hundred kms were via tropo
from the Azores and then coupled into a single Sporadic-E hop onwards to Europe.
Trans-Atlantic on 144 MHz??? The map below shows a 3000km circle centred on
the Azores...

Considering there was a 3000km opening on 144 MHz between the Azores and Germany on the 3rd of June, sure a 3000km path on 144 MHz from the Azores
to North America is possible?
Stations in St.John's, Newfoundland are close to the one hop Sporadic-E
range. Stations in Nova Scotia would need a tropo extension.
If the North Atlantic is going to be bridged on 144 MHz then surely Canada
to the Azores would be a first step in the process?

15,000km opening on 50 MHz between the Canary Islands & Guam in the Pacific
- 3rd June 2021

Posted: 03 Jun 2021 01:11 PM PDT https://ei7gl.blogspot.com/2021/06/15000km-opening-on-50-mhz-between.html



Thursday 3rd June 2021: Another day, another 15,000km opening on the 50 MHz band.... well almost. This time the longest opening seen on the PSK
Reporter website was the 14,966km path between KG6DX on the island of Guam
in the Pacific and EA8DBM on the island of Tenerife in the Canary Islands.EA8/DF4UE on the neighbouring island of Lanzarote was just 150kms behind.I checked the PSK Reporter site and there were paths open for both
to multiple stations in Japan as well. IF the signals took the direct path
then they crossed over the north of Russia.

Propagation Mode: At this stage, I suspect that we are looking at a
combination of different propagation modes. We have almost daily paths from Europe to Japan on 50 MHz at almost the same time as Noctilucent Clouds are making an appearance in the north of Europe and this may be a factor.
Chris, SP4K in Poland tells me that he is using a 7-element YU7EF Yagi on
50 MHz and he is working Japan on the direct beam heading of about 54
degrees. He also mentions that he noticed that the path to Australia is
skewed about 15 degrees to the North! In other words, he was getting VK3
and VK4 on the same beam heading as Japan. He also mentions that the path
to KG6 (Guam) and DU (Philippines) was on the direct beam heading.
Are the signals from Australia traveling north via TEP (Trans-Equatorial Propagation) to Japan and then skewed onwards to Europe via another
propagation mode?
It would be very interesting to hear about about other skewed paths on 50
MHz that people are experiencing.
