@JH4XSY thanks for opening a thread for that!

I’ve scheduled a couple of observations for 9th and 10th and I’ll try to keep tracking for the next days, however to station owners, please keep scheduling for these passes in your mind too.

PS I’ve changed the thread title to something more generic, in order to keep all the updates and interesting events for this satellite/mission here.

Today I got a MoG(Music of Geomagnetic) sound. KASHIWA generates this from 2-axis geomagnetic sensors.

Listen observation #9663995. It sounds like an alarm.

Nice catch!!!

If I’m not mistaken, with the loss of signal and/or the fluctuation on the power (if this is not part of the experiment) we can see the tumbling of the satellite.

Does anyone know if the times listed on the published schedule represent a single 10-15 minute session of activity over the listed location, or if it’s actually a START time for the downlink to be active for some longer period of time?

Thanks!

From a quick look it seems to be just for a single pass.

Thanks @JH4XSY! That’s very interesting.

For the next two scheduled events on 20th at 03:14 and 04:54, I’ve scheduled observations from 2024-06-20 00:00 to 2024-06-20 06:00 on both UHF and VHF transmitters.

Let’s see if we can observe again this difference in the satellite timer.
