[amsat-bb] Only US East Coast ISS SSTV Pass for Tuesday is at 16:30 UTC / 12:30 EDT

[Robert Bruninga]

Isnt there also a school contact at the same time?  I assume the school
will take priority over the SSTV?

The Moscow Aviation Institute ISS SSTV event, otherwise known as MAI-75,
which took place Monday [1] and will also run on Tuesday August 16th is
scheduled to stop at 16:45 UTC. [2] That leaves only one opportunity for
US and Canadian hams to receive the SSTV, during a single pass starting
around 16:30 UTC, or 12:30 EDT.

This assumes the Russians don't turn it off slightly before schedule,
which is a possibility as it isn't started and stopped exactly per
schedule. In the video above you can see the pass and some of the cities
it covers.

Note that even though it passes over a lot of cities, all but Miami will
be below 50 degrees which will make reception harder. For the lowest
elevations like Dallas with only 1 degree, you may only be able to receive
it with a directional antenna like the Arrow II Satellite antenna or a
base antenna with a very low radiation angle.

Below you can see the exact pass timing for various cities and the max
elevation. The cities are listed in order of max elevation. If you're in
or near a city towards the top of the list you'll have a decent chance of
receiving the ISS Slow Scan TV.

To find out exactly when the ISS will be passing over you or see the max
elevation for your location use http://heavens-above.com or another
website or mobile app to predict the pass.

Here is a video I made that shows how to setup heavens-above.com to track
the ISS:
