Since version 6.3, SkyMap has an option to find track segments where the
Sun is partially obscured.
It uses track colors dark blue and dark purple, but my color vision is so
poor I can barely tell the difference if I see them side by side.
Also there is a lot of trial and error, selecting the time and direction
to look, unless you have some coordinates for the umbra limit (or center
line) that you can convert to look angles.
If you produce a HPGL file, you can search for the SP (select pen)
commands, and compare to one without the flag below, and see which pen
codes are added (and locate the context, like time and sat name labels -
and chart location).

Added toggle (F8) in Lighting Constraint Menu to instruct
SkyMap to check if the sun is occulted by the moon as viewed
from the satellite. (This toggle should be set "Off" unless
you know a solar eclipse is occurring. The added overhead of
determining the moon's position will noticeably increase run
times.)
When F8 (Check for satellites in lunar umbra) is "On", program
determines if moon occults any portion of the sun as seen from
the satellite. If so, the satellite visual magnitude is adjusted
to account for the fraction of the sun occulted.
If the sun is more than 50% occulted, the satellite track color
is set to dark blue. (This is a slightly darker blue than the
blue used for tracks when the earth limb is blocking part of the
sun.) If the sun is more than 90% occulted, the satellite track
color is set to dark purple (a darker purple than that used for
tracks dimmer than the satellite magnitude limit).
