This morning – Bertrand Pinel, a keen amateur radio-astronomer who’s shared his work with us before – was awake to listen to Phobos making is Syzygy occultation of Mars Express.
At 01:11 UT (03:11 CEST), Mars Express was occulted by tiny Phobos, a roughly potato-shaped body measuring 27 km across its longest axis and 18 km across its shortest.
Bertrand (the same gentleman who gave us the Phobos sound recording) captured the drop in signal (as Phobos blocked the direct line of sight between MEX and Earth) using his own radio dish antenna in his garden in France. Some screen shots are included below from his signal processing equipment – you can see the gap and the times of occultation.
Thanks, Bertrand, for sharing!
Here are my screen shots and pictures of the event. Lucky with the meteo on this night; very stormy weather in South-West of France these last days. About the occultation of MEX signal by Phobos, I can see:
LOS @ 01:08:24 UTC
AOS @ 01:08:33 UTC
Giving an occultation time = 9″
