The two receptions below are completely plausible at this time of year near earliest sunset.
<<
first audibility of the Iranian jammer in Victoria, 22:54UT...may
have been there earlier? 90 minutes until local sunset.
best wishes,

UNIDENTIFIED. 1521, Nov 28 at 2044 UT, on my MW bandscan in western
Enid, KOKC OKC has a JBA het upon it! Roughly 1 kHz, but I can`t tell
exactly on caradio and whether it`s 1519 or 1521. Could the 2-megawatt
Saudi be propagating this early? (Hauser-OK)

Sunset here in MA late NOV / DEC is about 2115 UTC. A few years ago during a DX get-together at the Cape Cod house of Chris Black (N1CP), we witnessed 1521 Saudi het at noon EST / 1700 UTC and discernible audio 15 minutes later: 4 hours pre-sunset.
Inland sites can experience long-haul DX up to 2 hours before sunset; salt-water sites - as noted above - can be getting into the game up to 4 hours before sunset.
Shorter skip (<2000 km), especially on the upper half of the band, is pretty much an all day thing this time of year in northern states and anywhere in Canada.
