Correcting the azimuth/elevation to proper order :)   and adding phase
angle, we get:

NORAD  date      time  Dir aI eI aM eM  aS  eS Phs Dur Mag Obs 
24837 97-09-28 03:05:30 S 159 41 87 71 280 -18 125 ~5 -2 JR 97-030B

This may not be significant but the maximum elevation is about 15-20
degrees higher than most of the earlier flares.  Combined with a phase
angle about 15 degrees less, is it possible we are seeing different
flare conditions as the sun moves south?
