Tony,
How I rember is this:
Before noon the sun is rising so I put the sun below the AH image and after adjusting the sextant close, I allow the sun to rise into the AH image. Rising - upper limb.
Afternoon the sun is getting lower. Put the sun above the AH image and let the lowering sun go down and touch. Sun lowering - lower limb.
