Ga5-4 (*179)	Ga5-5 (**88)
September 16	17
spring equinox (179 - 92 = 87)

With Aldebaran at Ga1-4 (*69) and Antares at Ga7-16 (*250) we can assume there is one day for each glyph in the interval between them.

South of the equator a star is rising in the same calendar month as north of the equator. A good month for watching Antares from Easter Island should therefore be close to winter solstice in June. But the G text evidently has positioned the star in November, when it is rising heliacally.

If we wish to see Corvus we have to look at the night sky on the opposite side of the year compared to September and the month should be March (because 9 + 6 - 12 = 3).
