Schaefer and Liller and their co-workers have recently carried out a useful study in the important field of atmospheric refraction near the horizon. I A body of 144 measurements from various sites was collected and some pertinent analysis carried out. However, the authors conclude, inter alia, that "methods for aligning the Great Pyramid of Cheops to an accuracy of 2' cannot involve nearhorizon observations", and they assert that "the historically important claim by A. Thorn that British… 

REFRACTION AND PRECISE LUNAR ALIGNMENTS

During a major standstill the maximum declination of the moon at successive lunations varies by only a small amount. Observing the extreme north/south position of the moon would require an alignment

REFRACTION NEAR THE HORIZON

We have studied the variation of astronomical refraction near the horizon. We have collected 144 measurements of refraction from seven sites by three techniques and have found that the variation of
