When Does The Mid-Winter Anomaly Cease?

S

Steve_Green

I hope I have that spelled, if not suggested, correctly.

The topic I've seen here most on odd seasonal daytime reception was eaggerated groundwave DX in winter's broad daylight. Is this quirk the same thing as the Mid-Winter Anomaly I'd read about decades ago?

If so, how many shopping days are left? The oddity made for some good cabin fever eccenticities for a while. Are we past the peak?
 
I've recently been hearing 10kW 1680 KNTS Seattle, WA, at local noon just south of El Cajon, CA, about 1,070 miles away, so apparently we're still getting enhanced daytime reception. (I do get co-channel interference from KGED Fresno, CA, which is usually on top of the frequency, as well as occasional adjacent-channel from 1670 KHPY Moreno Valley, CA. KNTS can often be heard underneath, though, and has occasionally come up level with KGED or even risen above maybe a couple times.)
BTW I was using a Tecsun PL-606 with the Select-A-Tenna, and the signals were fairly weak (and completely undetectable without the loop, except for KHPY which has been sounding almost like a local at times.)
I don't know when the D-layer absorption will be back up, and all daytime reception will be strictly groundwave only. Anyone have any ideas when I should expect that at a latitude of 32°45'40"N?
