First, I have gathered there is no straight forward way of knowing where vernal equinox is in KSP using only stock game information but I was wondering:
KER has 2 items under Orbital:
Longitude of Ascending Node.
Angle To Equ. Ascending Node.
Both of these are in degrees.
To my brain, it sounds like one can use these 2 in tandem to determine where in the orbital path vernal equinox (VE) is. The Angle is the angle between the ship and AN. The LAN is the angle between VE and AN. When these 2 angles are equal, then you have found the "VN spot" for your orbit. By subtracting angles, you can determine where you are relative to VE.
Am I totally wrong or would this make sense? Any thoughts?
