Tuesday 24th January 2023: It looks as if there was another very short opening on the 50 MHz band but this time between Germany and New Zealand. It seems as if there was an impressive path of 18,646kms between DK6M in Germany and ZL4LV in New Zealand.
As far as I know, both parties managed to complete a FT8 contact. The FT8 signal from the ZL station peaked at -5dB in Germany.
The first thought of course is if the path is genuine? VK3WE in the SE of Australia also heard DK6M so there was a path open to that area. See Addendum below for a report from DK6M.
Txmtr Rcvr Band Mode Distance Time (UTC)
ZL4LV DK6M 6m FT8 18646 km 08:10:58
DK6M VK3WE 6m FT8 16592 km 08:59:41
SP4MPB in Poland also heard ZL4BV and was heard by DU6/PE1NSQ in the Philippines.
ZL4LV SP4MPB 6m FT8 17696 km 08:38:28
SP4MPB DU6/PE1NSQ 6m FT8 9839 km 09:20:44
Analysis... So what is going on? Why the short openings on 50 MHz?
