There was a total of 36 tracking passes in August of 1998 with 3 of these being unattended tracking passes. Of the 33 attended tracking passes 28 collected the maximum amount of valid data possible. Of the 3 unattended tracking passes only 1 collected the maximum amount of good data. There were 4 tracking passes that lost data due to problems on HALCA or HALCA pointing to the GBES late.

Of the 7 recording passes, 6 collected the maximum amount of good data while the other recording pass lost 8% of the data due to a station computer problem.



$\bullet$ 28 of 33 attended passes had max good data.

$\bullet$ Operators helped increase amount of good data in 4 of 5 ``bad'' attended passes.

$\bullet$ 1 of 3 unattended passes had max good data.

$\bullet$ Operators would have increased amount of good data in 0 of 2 ``bad'' unattended passes.

$\bullet$ A total of 2.21 tracking passes lost data due to problems with HALCA.

$\bullet$ A total of 0.29 tracking passes lost data due to software problems.

$\bullet$ A total of 0.47 tracking passes lost data due to hardware problems.

$\bullet$ 6 of 7 recording passes were completely successful.

$\bullet$ A total of 0.08 recording passes lost data.
