Gruline, Island of Mull


Gruline, Mull  (NM 5456 3960)  (See Ardnacross for Map)

1. Gruline, semi-wide,

A ridge to the north east gives two alignments for the rising sun.







2. Alignment with epochs 3,5


The sun at the solstice just fails to clear the rocky bump at 57º azimuth. The upper limb would be at the same feature 10 or 11 days before/after the solstice.


(The alignment at about 64º azimuth is discussed later.)
