In my so far completed list of bright stars there are now 7 + 10 = 17 items and I have tried to put them in parallel with the glyphs of G:

1st hour


Gb6-26	Gb6-27	Gb6-28 (411)
Caph (409.5), Sirrah (409.5)		Algenib (410.8)


Gb7-1	Gb7-2	Gb7-3	Gb7-4


Gb7-5	Gb7-6	Gb7-7 (418)
		Schedir (417.6), Deneb Kaitos (418.4)


Gb7-8	Gb7-9 (420)	Gb7-10	Gb7-11
Achird (419.7)		Cih (421.4)

2nd hour


*Gb7-12 (15)**	Gb7-13	Gb7-14 (425)	Gb7-15	Gb7-16	*Gb7-17 (20)**
		Mirach (425.0)


Gb7-18 (429)	Gb7-19	Gb7-20	Gb7-21 (432)
Ksora (429.1)			Achernar (432.3)


Gb7-22	Gb7-23	Gb7-24	Gb7-25 (436)	Gb7-26	Gb7-27
		Polaris (435.6), Baten Kaitos (435.6), Metallah (435.9), Segin (436.2), Mesarthim (436.2), Sheratan (436.4)			Alrisha (438.2)

My model assumes 1h coincides with 15.2 days counted from Rogo in Gb6-26 (because 60 / 1440 * 365.25 = 15.2).

To get rid of 0.2 we could instead use a year with 360 days (= 360º), and then 15º will correspond to half a month.

60 / 1440 * 360 = 15 and each right ascension minute would then correspond to exactly a ¼ of day (= 6 hours).

Sheratan, for example, would then be at day number 112 / 1440 * 360 = 28.0. This will be precisely at Gb7-25, because 408 + 28 = 436.

Although such a model seems to be better, it does not, however, fit a reality which has a year with 365.25 days. I will therefore keep my so far used model.

After another 15.2 days 2h will be reached, and 408 + 15.2 + 15.2 = 438.4 is the corresponding glyph number. Alrisha - the 'knot' in Pisces - is at the very end of the 2nd hour.

Counting glyphs there are (3 + 4) + (3 + 4) = 14 in the 1st hour and 6 + 4 + 6 = 16 in the 2nd hour, together 30. Converting right ascension minutes for the first 2 hours into days means dividing 120 by 4.
