The rongorongo glyphs seem to refer to a grid of right ascension days and therefore April 23 (Bb11-33) at Mira/Khambalia should be ca 16 days before these stars returned to visibility (in day 129 resptively in 312). Although my assumption of *64 precessional right ascension days down to the Golden Era of the Bull need to be adjusted with +16 days in order to accommodate for the ancient rule of return to visibility. For instance 49 (FEBRUARY 18) + 16 = 65 (MARCH 6). As I have hinted at below this fact might well be responsible for how half a year later than the true heliacal dates the corresponding nakshatra day numbers evidently are 16 days lower than the intended numbers. 664 (October 26) for instance, when the star 71 Virginis returned to visibility after the close encounter with the rising Sun, was 16 days after October 10, its true heliacal right ascension day. The number of glyphs on side b of the A tablet was designed to be 664. Observation of the stars at the Full Moon were not impeded by the rays from the rising Sun.

Niu. Palm tree, coconut tree; hua niu, coconut. Vanaga. Coconut, palm, spinning top.  P Pau., Ta.: niu, coconut. Mgv.: niu, a top; niu mea, coconut. Mq.: niu, coconut, a top. Churchill. The fruit of miro. Buck. T. 1. Coconut palm. 2. Sign for peace. Henry. The sense of top lies in the fact that the bud end of a coconut shell is used for spinning, both in the sport of children and as a means of applying to island life the practical side of the doctrine of chances. Thus it may be that in New Zealand, in latitudes higher than are grateful to the coconut, the divination sense has persisted even to different implements whereby the arbitrament of fate may be declared. Churchill 2.

Nikau. Mgv.: The coco palm. Ta.: niau, coconut leaf. Ha.: niau, stem of the coconut leaf. Ma.: nikau, an areca palm. Churchill. Mgv.: niu, the coconut palm when young, ripening into nikau. ... the ni of New Caledonia leads us to infer that niu was anciently a composite in which ni carried at least some sort of generic sense, it being understood that this refers to those characteristics which might strike the islanders as indicating a genus. In composition with kau tree we should then see nikau, the ni-tree, serving in Mangareva for the coconut palm, in New Zealand for the characteristic palm (Areca sapida) of that land, in Tahiti as niau for coconut leaf, and as niau in Hawaii for the leaf stalk of the coconut. The ni-form is found in Micronesia, and in the Marshall Islands ni is the coconut. Churchill 2.

Nika. 'Savage tribes knew the Pleiades familiarly, as well as did the people of ancient and modern civilization; and Ellis wrote of the natives of the Society and Tonga Islands, who called these stars Matarii, the Little Eyes: The two seasons of the year were divided by the Pleiades; the first, Matarii i nia, the Pleiades Above, commenced when, in the evening, those stars appeared on the horizon, and continued while, after sunset, they were above. The other season, Matarii i raro, the Pleiades Below, began when, at sunset, they ceased to be visible, and continued till, in the evening, they appeared again above the horizon. Gill gives a similar story from the Hervey group, where the Little Eyes are Matariki, and at one time but a single star, so bright that their god Tane in envy got hold of Aumea, our Aldebaran, and, accompanied by Mere, our Sirius, chased the offender, who took refuge in a stream. Mere, however, drained off the water, and Tane hurled Aumea at the fugitive, breaking him into the six pieces that we now see, whence the native name for the fragments, Tauono, the Six, quoted by Flammarion as Tau, both titles singularly like the Latin Taurus. They were the favorite one of the various avelas, or guides at sea in night voyages from one island to another; and, as opening the year, objects of worship down to 1857, when Christianity prevailed throughout these islands.' (Allen)

... When the 'Crooked Claw' (Khambalia) - the reaper's instrument - was seen at the Full Moon in April 23 it portended death of the southern summer year.

And when Mira was at the Full Moon in October 23 it was the opposite, the death of the winter year:
