Tony -

We heard something intriguing after about 14:43:40 UT as the tracking said the satellite was on it's way off to the north pole.

The 'chuff-chuff' description reminds me of a sound we seem to hear quite a lot. Quite often it coincides with a pass, though I think we hear the same (or very similar) during times when Prospero is over the horizon.

We are going to try the next pass at ~16:00UT if you want to listen in again. Our new ploy is to wait for the last most opportune moment to command, as the power _may_ be at it highest (longest charging of batteries, potentially). So, we'll do short commanding at above 30o el, and listen.

Hi Roger

I could hear some "chuff-chuff" noises on the last pass and they show a related doppler shift (although I am not correcting sufficiently) as you can see in the attached plot. Maybe its some other noise but you never know.

Commanding went well, from as far as we could make out. We're not sure if we're getting anything back, however.

We'll be doing this pass today, hopefully:
