The band was pretty much open for a full ten hours from about 09:00 to 19:00 UTC.
The opening was especially good to the south with strong signals from Spain and Portugal. I heard a lot of traffic from South America as well which isn't the best direction from here due to a local hill.
The map below shows the closer signals in more detail. Some of the signals not uploaded to PSK Reporter are shown as extra pink dots.
Notes...
1) The single hop limit is shown by a Yellow dotted line. The signals to note here are the double hop ones to Western Sahara, Greece, Israel, Bulgaria and Ukraine. However on closer inspection, there aren't that many to the east.
2) There was single hop Sporadic-E into Germany but the number of stations for a country of that size was low.
3) While it was a widespread opening with different areas of Europe being heard at the same time, most of the signals were modest. The signals from the south however was especially strong.
4) I wasn't listening on the FT8 frequency all of the time. I did tune around a few times and I did work some of the Spanish AM70 stations on cw. However, the radio was probably on the FT8 frequency for at least 90% of the day so it's a good reflection on what was happening on the band.
Beacons...These are the beacons that I heard and they reflect the very good conditions to the south. The ED4YAK beacon near Madrid was noticeably the strongest of the lot.

The band was also open much further south with 9J2BO in Zambia being heard on cw.

The special event AM70 stations in Spain were really strong and I worked AM70O, AM70R, AM70P and AM70L on cw.
I heard someone on RTTY as well which seemed unusual, especially for 28 MHz.
One odd signal was an illegal fishing buoy on 28.029 MHz.
50 MHz... I did check 50 MHz at one stage and I heard a beacon in Portugal.

While I was there, I didn't hear any other signals except for the FT8 frequency.
According to the PSK Reporter website, I uploaded 456 reports for 28 MHz from 311 different stations in 41 different countries. A list is show below.
