Abstract
A RÉSUMÉ has been issued of the observations of solar prominences made at Madrid during 1941 (Bol. Astron. Observ. Madrid, 3, No. 2 ; 1944). The observations were conducted by E. Gullón with the 20-cm. Grubb equatorial, focal length 3 metres, equipped with a Zeiss spectroscope. Observations of sunspots made at the Observatories of Madrid, Valencia and Cartuja (Granada) in 1941 are given graphically in six diagrams, each diagram showing a separate graph for each of the observatories. M. Martin Lorón provides a table showing the results of observations of occultations of stars by the moon during the years 1941, 1942 and 1943. The reduction of the observations was effected by Comrie's method which appeared in the “Supplement to the Nautical Almanac”, 1938. No. 3 of the Boletin continues the record of sunspots for the year 1942, and contains separate sections on three remarkable solar prominences observed in 1936 by Enrique Gullón at the Observatory of Madrid ; on the observations of Mars during the opposition of 1939, by Enrique Gullón and Mariano Martin Lorón; and on occultations during 1944, by M. Martin Lorón.
