During the twilight hours, the observation of the star Aldebaran yielded a meridian passage recorded at 19:25 GMT. The azimuth was measured at approximately 150° with a corresponding altitude of 45° as referenced by the vessel's astrolabe.
Further calculations indicated a deviation in the lunar arc trajectory, prompting a reconsideration of ephemeris adjustments.
Subsequent to the heliacal rising of Sirius, navigational markers were recalibrated with a focus on positional latitude set at 26° North. This entry includes the noted influence of geomagnetic disturbances affecting compass reliability.
The assessment concludes with an inquiry into the synodic period of Jupiter, establishing a correlation with cyclical tidal patterns.
A comprehensive review of the celestial arc was undertaken, wherein the observation of Vega's luminosity was paramount. The log reflects a meticulous azimuth angle of 210° and an altitude of 60°.
Anomalous readings in the stellar backdrop prompted a supplementary spectral analysis to discern potential astroclimatic shifts.
