Hi Jay,

EZ1 is a pretty good reference beacon. He shows up after my local sunrise and I'm hoping he's still around at sunrise and beyond. I have a good idea that the ionosphere cools off more slowly at sundown (recombination is a slower process) than at sunrise (ionization is a faster process). Almost due south at the right single bounce distance being 680 nm away.

By having the WSPR data you can visually compare the WSPR trace to the QRSS ones. I was amazed to see that sometimes the QRSS signals were stronger and at times weaker at various time intervals. There's probably more ways to get comparative data but this was the quick and easy way using an interval screen capture program and a fixed in one place window to FTP to the grabber page every 10 minutes.

Thanks and glad you like the page. I keep all the grabs archive on my T-byte HD. I use Irfan View to flip through the images and make a pseudo movie of the Spectrum Lab raw screen grabs. Easy to spot something that shows up out of the blue. Same idea with astronomy images (flip comparator) looking for anything that jumps out of fixed star patterns and moves.
