Get a 1st surface mirror, no ripples, no freezing, (well except for you).  Remember to level it.  $20 for a 6 X 6 1/4 thick glass unit from www.firstsurfacemirror.com  It is more accurate to measure limb on limb.  Try UL in morning letting the sun rise up to the AH reflection and subtract semi-diameter.  In the PM LL let the sun fall into the AH reflection and add semi-diameter.
