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:
