Newfoundland 144 MHz monitoring station VO1FN hears US station at 1760kms - 13th June 2021

Normally, a reception report of a station at 1700km on the 144 MHz band
isn't all that special as we're in the middle of the Summer Sporadic-E
season but I found this one of interest.

13th June 2021: The VO1FN station at St.John's, Newfoundland was set up to monitor the 144 MHz for Trans-Atlantic signals. On the 13th of June, it
heard a FT8 signal from K1TEO in Connecticut in the USA.

The distance was just over 1760 kms which is pretty typical for Sporadic-E
or meteor scatter at 144 MHz.
This is the tropo prediction map for the day from Pascal, F5LEN...

It shows some enhancement on the 1760 km path but probably not enough to explain the propagation mode.
Propagation Mode: Frank, VO1HP outlined in the update at the end of this
post how the signal was heard off the back of the beam. As there was just
one decode, I don't think it was tropo. If it was meteor scatter then it required a burst that was at least 15 seconds long. The other option was a
very short Sporadic-E opening.
My interest in this reception report is how it compares to the distance
from Newfoundland to the Azores Islands.

The beam heading from VO1FN to K1TEO is 254 degrees which is 16 degrees
south of West. I calculated what the equivalent point is at 16 degrees
south of East and it is shown above.
As you can see, the distance to the Azores is just a few hundred kms.
It's my opinion that proof of a 144 MHz path between Newfoundland and the Azores would be a valuable first step in the eventual goal of a
Trans-Atlantic 144 MHz contact on 2-metres. I think this is most likely to happen between the north-west of Spain / Portugal and either Newfoundland
or Nova Scotia in Canada.
Update 15th June: From Frank, VO1HP... "The antennas were pointing at
Ireland. I regularly monitor 144.174 even though EI2DKH is opearting on 144.488Mhz Q65 every time there is an opening on 6M. The actual decode
took place on Jun 13 2021 not Jun 14. Jun 14 was the date displayed by
WSJT-X on Monday when I logged on to the PC using Anydesk. The time stamp
of the recording is 20210613_101845"
