They suggested that this longitudinal anomaly is caused by the difference in magnetic declination that gives rise to upward and downward ion drifts across the zero declination for a given thermospheric zonal wind direction.
If we look at all sources observed in more than 25 sessions (in total 311 sources), we find that the Kalman filter gives better repeatabilities in right ascension for 280 sources and in declination for 277 sources.
They have suggested that this longitudinal anomaly is caused by the difference in magnetic declination, which gives rise to upward and downward ion drifts across the zero declination for a given thermospheric zonal wind direction.
To evaluate the tectonic evolution of the Korean Peninsula, temporal evolution of vertical rotations between the observed and expected magnetic declination for all the available paleopoles documented in the peer-reviewed literature with modern paleomagnetic standards was displayed (Figure 11).
The magnetic field components (dip and declination) for this region are calculated using the International Geomagnetic Reference Field IGRFF) 11 and shown in Figure 3a,b with dotted lines.
In (4), ω1 and ω2 are the hour angles at the beginning and end, respectively, of the hour in question ( ω = 15 ∘ 12 - h, with h the solar time), and ωs is the sunset hour angle for the day equal to cos - 1 - tan δ tan ϕ, with ϕ latitude of the location and δ declination for the day, which can be computed by means of the Cooper's or Spencer's formulas [33, chap. 1].

To determine the relative declinations for as long a continuous interval as possible, for each core segment, we confirmed whether its end surface could be connected to the next core segment and carefully checked the connection between the two segments without any horizontal rotation to ensure the continuity of the core.
By far the most frequently reported reason for declination of participation was too long commuting time to the training facility.
The model will serve as a tool for practical purposes, e.g. to provide declination information for navigational applications.
Thus, to accurately adjust your compass to account for this effect, you'll need a recent declination value for your location.
Orion, in astronomy, major constellation lying at about 5 hours 30 minutes right ascension and 0° declination, named for the Greek mythological hunter.
