1. Below are listed the stars which at present are rising heliacally in the 8th hour according to my astronomy book. I have also redmarked the remaining stars in Gemini and put them in parallel with the glyphs in G:

Alhena

ε Canis Majoris 1.50 28° 54′ S 06h 57m 105.8 513.8

Ga2-9 Ga2-10 Ga2-11 (42)
  Alhena (104.8) Adara (105.8)

8th hour:

Ga2-12 (*107) Ga2-13 Ga2-14 (45) Ga2-15 Ga2-16 Ga2-17
        Wasat (110.8)  
Ga2-18 Ga2-19 (*114) Ga2-20 Ga2-21 (52) Ga2-22 Ga2-23
  Castor (114.4)     Pollux (117.2)  
Ga2-24 Ga2-25 (*120) Ga2-26
Ga2-27 Ga2-28 (59) Ga2-29 (*124)

Beginning with Ga2-12 I have abandoned my earlier number colours; Mars ought to be in focus at such cardinal numbers as 14, 52, and 59. Furthermore, 42 (and 2 * 11 = 22, a sign of π) indicates Adara should close the cycle ending at 07h. Hakaturou should be the definite sign of this.

From Ga2-12 there are 18 glyphs to the end of line a2. However, 8 / 24 * 365.25 = 121¾ points to Rei in Ga2-27 as the beginning of the 9th hour.

 2-27 at Rei probably alludes to 22 / 7 (= π). And 22 * 7 = 154 = 2 * 77, as if to allude to the Twins.
