Photographic Determination of Heliographic Coordinates of Sunspots Without Taking Double Photos
Publications of the Department of Astronomy, Tome 6 (1976), p. 65
The idea of the method is to achieve high precision in determination heliographic coordinates of sunspots, without taking double exposure photographs. For this purpose, with a level, the parallelity of one side of the photographic plate to the horizont is ensured. The moment of exposure is noted in UT.
