Since 1358z I have been on 10m WSPR TX with my 500mW W5OLF beacon. It is now 1310z and so far no spots.
UPDATE 1326z: Spotted several times in the Canary Islands.
UPDATE 1546z: First spot today from the USA received on 10m WSPR. It is a pity the USA stations no longer have prefixes that point to locations. In years gone past W7 would have meant western USA. No longer!
UPDATE 1707z: Just 3 unique stations spotted today.
