[amsat-bb] Some AO-51 TLM observations

[Bent, OZ6BL]

Hi

The attached picture is a screenshot of some recent TLM data taken off 
www.amsat.dk/oz7sat/tlm/

The battery voltage curve is the one that I find interesting. It appears 
to contain two superimposed sine curves. Can anyone interpret this? The 
period time is approx 3 minutes. Is this consistent with the rotation of 
AO-51?

Best 73,
