Hi August,

On 2021-12-26 09:48:00, you wrote to me:

That's odd, because he is connected to that area on my system, so he got it
direct. (And my outbound is empty)

 WvV>> It's now, a day after launch, almost 240 km from earth.
                                            ^^^^^^
That should have been: 240K km! :/

 WvV>> That's not even half way the distance to the moon. And

Indeed.

 WvV>> If you're interested you can follow it's journey..

That also took days? ;-)

 AA> But what do the gaps between day 2-3, 9-10, 11-12, 14-15, 26-29

I don't know, I was wondering about that too. And it doesn't seem to correlate
too well to the deployment steps...

 AA> At about 1.5-2mi/sec hope there isn't any teeny tiny debri that
 AA> can render it useless.

There's always that tiny, tiny, tiny risk. But it's already well beyond the
"commercial" earth orbits, so that debri wouldn't be human made...

Bye, Wilfred.
