I just noticed something about which I'm confused: If the height of the ISS above the earth at culmination is 223.45 miles, how is it that it is only 222.70 miles distant? (I had to convert to miles to be able to visualize things. ;-) Kim -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Patrick Wiggins Sent: Monday, September 13, 2010 1:11 PM To: utah astronomy utah astronomy listserve Subject: [Utah-astronomy] ISS this evening

Might it have something to do with one's altitude? I noticed the ISS just missing the moon last night, from the fairgrounds. I'm thinking someone a few miles further south might have seen a transit. On 9/13/10, Kim <kimharch@cut.net> wrote:

That might be correct if the height above the earth is calculated from the geoid, and that actually makes sense to me. Ill accept that answer.
