Following is an extract from my SOL
(Satellite Observation Log).
Just to show the different magnitudes
of Kosmos 1461.
 
It reports all transits seen by me
of 83- 44 A/14064 Kosmos 1461.
 
The column headings mean:
yymmdd: year-month-day_of_month
hhmm:   time in hours and minutes (UT)
satid:  COSPAR-id of satellite in
        seven digits.
m       motion: A = ascending (to northern apex)
                D = descending (to southern apex)
max     maximum brightess estimation of just
        brightness estimation at brightest.
A       appearance: S = Steady; V = variable
                R = regular; I = irregular;
                F = flashing
min     minimum brightness estimation
