Gurteenaduige Standing Stone is a couple of kilometres north of Leap. It is quite large, a ringfort is nearby to the south and Standing Stone Pair CO133-05901 is about 150m to its north-west.

NW from Gurteenaduige Standing Stone, Cork, Ireland.

An obvious step in the north-western hillslope marks both the sixteenth on the minor side of the lunar mid­point and the half-month bracket for the cross-quarter as it does from the pair. The hilltop marks 3/32 of the lunisticeLunistices are the most northerly and southerly moons of the month. The lunar equivalent of solstices - more. range away from the major standstillLunistice positions vary cyclically over an 18.6 year period but are fairly static for more than a year at either end of the range. This is a difference of 1/32 to the value obtained from the pair.

Green lines approximate hidden horizon segments.

NE from Gurteenaduige Standing Stone, Cork, Ireland. To the north-east is Carrig Fadda. Once again the point surveyed here as a sixteenth from the lunar standstillLunistice positions vary cyclically over an 18.6 year period but are fairly static for more than a year at either end of the range is different from the value obtained from the pair by 1/32. This time the difference being the other way round as it is Max-3/32 from there. This is a further indication that the Standing Stone and Pair were built to complement each other and also that they were deliberately measuring the lunisticeLunistices are the most northerly and southerly moons of the month. The lunar equivalent of solstices - more. range in thirtysecondths.

E from Gurteenaduige Standing Stone, Cork, Ireland. To the east, the view of the equinoctial zone is essentially the same as from the pair.

SE from Gurteenaduige Standing Stone, Cork, Ireland. The south-east is also the same from here as from the pair, with declination differences being less than 0.1°. This is because the positional displacement is in that direction and the horizon is fairly distant.

SW from Gurteenaduige Standing Stone, Cork, Ireland. To the south-west the differences are significant but this segment is largely obscured from the pair. From here the lunar limit is on the hilltop though once again we have the sixteenth rather than the standstillLunistice positions vary cyclically over an 18.6 year period but are fairly static for more than a year at either end of the range itself.

W from Gurteenaduige Standing Stone, Cork, Ireland. The west is obscured by a hedge.
