The AO51 mobile tracking table only has 5 entries because the pass times repeat every 5 days so it can be reduced to a single table good for 2 months like this:

EASTERN Daylight Time AO-51 01Aug 07Aug 13Aug 19Aug 25Aug ----- ----- ----- ----- ----- 0800 0855 0815 0740 0835 0935 0920

1910 2010 1930 1850 1950 2030

Cut/paste on your dashboard or shack bench. The table is good for a month or two and allows you to always estimate satellite passes within 5 minutes. You don't need no stinking PC for 2 months. These are the peak passes for your time zone. If one peak pass is shown, then there are two other lower passes 100 minutes earlier and later. If two modest passes are shown, then the others will probably be too low.

TO use this on any day, just find the column nearest todays date and count forward or backward the number of days. SO for today (July 29th), start on 1 Aug and count (rotate) to the left 3 days. So tonight's pass will be at 1930 (and one at 1750 and 2110 ish)

I updated the tables for both birds and each USA time zone on my Mobile Manual Tracking web page:

There are other hints there that allow you to be more accurate based on where you live in your time zone, etc. The table for the GO32 APRS satellite repeats every 9 days and is good for 3 months or so:

EASTERN Daylight Time 01Aug 11Aug 21Aug 31Aug 10Sep 20Sep 30Sep 10Oct 20Oct ----- ----- ----- ----- ----- ----- ----- ----- ----- 0920 0855 0835 0810 0930 0905 0845 0820 0940 1015 0950 1025 1000

2035 2015 1955 1930 2005 2025 2005 1940 1920 2135 2110 2120 2100

If you get bored on your daily commute and want to see what the satellites are doing and you are on the road during these times, you don't need a PC. Just look at your dashboard, do a little mental processing, and bingo, you can estimate the next pass easily.
