EME planner
Plan Earth-Moon-Earth contacts ahead of time: which days are best from your station, when the Moon is up at both ends of the path, and what Doppler and polarization to expect.
Right now
Best days of the next 30
Each bar is the best moment of the day with the Moon above your minimum elevation. Degradation is the loss against the Moon at its closest in a cold part of the sky, with an 80 K receiver. It covers distance and sky noise. Days with the Moon within 15° of the Sun are never listed as best.
Windows with the DX station, next 14 days
Polarization offset is the spatial part only. Faraday rotation adds to it and cannot be predicted: it dominates on 144 MHz and below, so nothing is shown there, and it is about as strong as the offset on 432 MHz, so that value is only a guide. From 1296 MHz the offset is what counts.
EME beacons
Hearing a beacon tests your receive side without transmitting anything.
From what the beacon operators have published; a beacon can be off without notice, so check DL0SHF and the HB9Q logger before you trust a silent band.
All times are UTC. Degradation, spread and polarization offset follow the WSJT-X Astronomical Data window. Sky temperature: Haslam 408 MHz map (Remazeilles et al. 2015) from NASA LAMBDA. Moon position agrees with JPL Horizons to 0.03°, and the echo Doppler to 2 Hz on 1296 MHz and 15 Hz on 10 GHz.
