Big amplitude, in the "real" region, but incomaptible w/ overlapping Ayiomamitis LC. This is puzzling.

Although the amplitude is in my "maybe" region I somehow question the reality of this variation.

This variation is in the "real" region of my spurious amplitude diagram. However, the period is almost as long as the observing session length, and the pattern is correlated with air mass, so this detection deserves confirmation by another observer's LC before being accepted as real. The plot below shows how it is incompatible with the overlapping LC by Salas.

The large amplitude variation must be due to clouds because there's overlap with Wiggins (below) showing 5.5 mmag variation.
