Markus,

 

I=92m=20 glad that you suggested a 2-hour time slot (if it works for Bob). Based = on your=20 NAA spectrogram (attached), the window that you=92re shooting for may be = a=20 multimode interference peak, which might be shifted (an hour or so?) for = a Penn=20 Yan path; and I don=92t know which direction in time the window would = shift.=20

 

Paul=20 is doing so many things that I hate to mention this, but I wonder if = LWPC would=20 show the interference peak near 1500 UT; and if so, which direction in = time the=20 peak would shift for the Penn Yan path.

 

I=20 seem to remember that Paul provided an online interface to LWPC, I=92ll = see if I=20 can find it.
