Australia 1548 in at Nick's end 3 hours after sunrise is kind of like the
mirror image of what happens here on the East Coast with some TA stations
coming in 3 or more hours before sunset at shore sites.
In the NOV/DEC stretch several years back, Saudi Arabia 1521 was received at
East Harwich, MA at 1 p.m. EST / 1800 UTC and on another occasion right here in
South Yarmouth (former QTH of Chris Black, N1CP) with carrier at 1730 UTC, good
audio by 1800. Earliest Cape Cod sunset is 4:10 p.m. EST / 2110 UTC.
The extreme case is Cappahayden, Newfoundland where the old Norway 1314 blaster
was audible all day on skip in late autumn. Of course that's dealing with much
less distance (and more power) than TP routes from most of western North
America.
It does say that quite a bit of a path can be in daylight while some degree of
skywave propagation is supported.
Azores 693, another now-silent TA, was all day to Cappahayden but that was
actually GROUNDWAVE (about 1240 miles / 2000 km), a similar distance to the
Turks and Caicos to West Dennis Beach, MA reliable-groundwave run enjoyed in
530's high power days.
I wonder if any Asians make it Alaska or Hawaii via groundwave.
Of course a chunk of Alaska has "all day" skip reception during its lengthy
winter when the sun barely gets above the horizon.

A belated thank you to Craig and Walt for their DXpedition reports
for this date. I'll round it out with a report from Tofino
BC, using a NetSDR and ALA100 pair.
First noted Tonga with quite a good signal, island music and talk
before 0600UT.
Then, after 1300UT quite a lot of Japanese, including NHK1 on 946 and
NHK2 on 1386 in addition to the larger guns, but 1593 was CNR1, and
maybe Tagalog on 837, and Korean on 657....then there were commercial
Japanese such as 1242 1314 1332 1179 954 918 etc. In addition,
there was a preacher on 1611, but couldn't hear anything definite
for // on 1629; just a rumble. This all lasted until about 1400UT,
when all Asians, except the big guns, wandered off, leaving a number
of down unders, and by 1440UT, it was all down under, most not too
strong, but some of which just wouldn't quit.
DUs continued popping up erratically until well after 1530UT; figured
that everything was over by 1550UT, but no, 1116, 1548 were still
there, just not regularly, but heck , 1548 particularly just wouldn't
go; at 1631UT, it was as strong as the 1550 domestics (admittedly,
not strong there), and finally sailed away, I think, at 1700UT with
the ABC news fanfare heard weakly, three hours after local sunrise,
with the terminator out past Hawaii by this time.
So, actually, not a bad morning. I'm surprised that DUs didn't make
more of an appearance at Rockaway judging by that
performance. However, they weren't really pounding in, and domestic
interference after sunrise is fairly weak at Tofino, so it might have
been a signal to interference issue, plus equipment difference.
best wishes,
Nick
