The Transit Instrument Under Optimum Conditions
On the basis of experience with RA determinations during the polar nights of 1974–1977 on West Spitzbergen and of RA determinations of the Sun, Mercury and Venus at high latitutes one can conclude as follows: At high geographical latitudes the polar night conditions are nearly optimal for absolute d...
