Dear Alan, the horizon is too near to do checks - but VERY crude ones. The most accurate I.E. check/measurement is measuring Sun's diameter - across - in horizontal direction; with left-right limbs. This excludes any effects of the atmospheric refraction - which are there if the upper-lower limbs are used.
Hope that helps.
Regards,
Tony
