Yes, I am on the dark side, not a HP-65 HP 67 kind of guy. TI vs
HP, PC vs Mac. The nerd wars continue. I enjoyed your comment as it
brought back all the discussions at that time. I could smile and
enjoy sharing the memory with you

Hi Brooke,
A close up of one slot, but the photo is wide enough to show more than five
satellites. Or am I missing something here.

for you.

I think I found the math to determine look angles:
http://www.freeclassnotesonline.com/Satellite-Look-Angle.php
It's beyond me, but my guess is that we could solve for latitude and
longitude if we know satellite location, azimuth and elevation.
I have been wondering why I can determine my latitude using simple
tools but not my longitude? The earth is a sphere, I would think if
you can determine one you can determine both.
The problem with calculating longitude seems to be the earth is
rotating on its' axis. If the earth stopped
In general, you cannot see geostationary satellites with the naked
eye. See http://www.satobs.org/geosats.html for details. To be
visible to the naked eye, an object's apparent magnitude must be about
6 or greater (smaller values are brighter). Most satellites have
magnitudes around 12 or
probably have to aim a dish at it and see what TV stations you get.

That's what I was hoping for.
Okay if I can find those 5 for example, I could choose one of them.
Maybe the one on the right and keep using that one for reference.
Or, maybe choose the brightest

Hi
The idea of personal prime meridians is entertaining but it probably
isn't very practical.
For example, if I discovered some nice island, how could I tell others
where it was. My directions would be worthless to them, unless they
started from where I did.
It reminds me of personal time

That's an interesting suggestion about the satellite dish.
I have a tv dish now, which is aimed at a geostationary satellite.
I think if I go measure its' inclination from the north/south horizon
and its' inclination from the east/west horizon I can
