10m Es and early morning MS?

LB9YE and I have been exchanging WSPR spots since 0458z this morning. In both directions there is considerable Doppler. On another signal (not currently decoding) there are clear signs of meteor reflections as the signals are strong but in short bursts. I wonder if MS was playing a part in LB9YE’s decodes?

Earier in the night PB0AIC (288km) was decoded STRONGLY at -8dB S/N . At this range I assumes this was early morning tropo or again possibly MS? At the very same time 0404z, G8VDQ (93km) , was decoded strongly at -12dB S/N.

Otherwise all quiet on the Es front.

I do wonder sometimes about Es (SPORADIC E-layer) reflections. Many signals do come into this category with fleeting, often quite localised, strong openings, but many others are anything but sporadic. Are these really Es as we know it or some other propagation?
