[amsat-bb] Russian Thing

[Paul Andrews]

Paul,

Thanks for the update.    Without the sail deployed the 10cm x 10cm x
10cm satellite's luminance is still very low.   It should be much more
interesting when the 170 sq ft sail is deployed.   This sail is still
smaller than the ISS solar panels.

I will be in up state New Hampshire during the first week of August.
I hope the sail is deployed and I see a light show.

When I return to my FN20 QTH, I hope to try meteor scatter techniques
to make a QSO off the sail.  I'm sure many others will try as well.
Scatter QSOs off the ISS are rare.
