Your first file showed 7 sun hits and 2 moon hits, you altered perimeters for the moon and your second file reads as 5 sun hits and 6 moon hits ... what happened to the 2 previously recorded sun hits ?.   The following is my sun hit list between 16th - 28th Jan ...

16th Jan M 5.8 Vanuatu .............................. 01:16:38 ut ... CS 163' 16' E ( 163' 59' E - 12th Jan )

24th Jan M 5.0 South Georgia Island Region  02:38:40 ut ... CS 143' 21' E ( 144' 11' E - 15th Jan )


16th to 28th Jan = 10 sun hits

I have used NEIC records and http://www.fourmilab.ch/cgi-bin/Earth to determine these times and locations.  In each case, the sun is within +/- 1 degree of the bearings posted in the table. I can only conclude that either the formilab data is wrong, or you have a bug in your program.   If it is the latter, and is giving unreliable results over such a short period, it would also be fair to assume the 1973 run is also in question !  

I used the same source of information as you did, perhaps you should check my source to confirm we are not miss-understanding my results as being due to human error.

Duffy;

Thank you, this is exactly what I need to check my results.

Would you also send the moon hits for comparison?

As I said, in order to check my program, I need to know the right answers
