The agenda for the meeting in Stockholm are:(1)Report on the progress of the FK3 catalogue, and the volume of apparent places of the stars in this catalogue.(2)At the meeting in Paris it was suggested that the value of the Gaussian constant k should be fixed, and the President was asked to consult people known to be interested. As complete agreement appears to have been reached, the following resolution will be moved: “That the value of the Gaussian constant k shall be taken as 0-01720 20989 50000, the unit of time being the mean solar day for 1900·0”
On July 31, 1930, Commission 3 reported that the names of two stars to which two names are commonly given had been settled. These two stars are:Gamma Scorpii = Sigma LibraeUpsilon Persei = 51 AndromedaeThey have been fixed as in Libra and Andromeda respectively. In accordance with the suggestion of the Secretary of the Union, this report was communicated to the Directors of the Nautical Almanacs, no objection being raised by the members of the Commission.
At the 1932 meeting three proposals before the Commission were referred to the directors of the national ephemerides (Trans. I.A.U. 4, 222, 282).(1)That the equation of time be given with the same sign in all almanacs.(2)The question of duplicate printing.(3)The possibility of adopting a uniform system for star positions.Although the directors have discussed these by correspondence, they wish to take the opportunity of verbal discussion in Paris before presenting their final report. The proposal that duplicate printing of apparent places of stars should be eliminated has been favourably received. A joint meeting with Commission 8 is being arranged for the purpose of discussing the selection and positions of future fundamental stars; at present the general trend of opinion favours the adoption of the FK3 of the Berliner Jahrbuch.
