AbstractWe describe the history of solar-eclipse supervision since the formation of the International Astronomical Union, as the supervising body morphed from a full commission to a subcommission to its current status as an Inter-Divisional Working Group of the Education, Outreach and Heritage Division and the Sun and Heliosphere Division.

The IAU Division C Commission 55, Communicating Astronomy with the Public, played an active role in Union affairs within Division C, Education, Outreach and Heritage. The International Astronomical Union (IAU) vested considerable responsibility for its public outreach efforts in Commission 55 (C55), Communicating Astronomy with the Public. This article briefly recounts the origin and history of C55 over the past decade, and describes the work of C55 until it became Division C Commission C.C2 in 2015. As stated on our website, http://www.communicatingastronomy.org, C55 was founded on the principle that “it is the responsibility of every practising astronomer to play some role in explaining the interest and value of science to our real employers, the taxpayers of the world.” While this was true a decade ago, when the Working Group that eventually became C55 first took shape, it is even more true today, when funding for the astronomical sciences (and science more generally) is under threat on nearly every continent.

AbstractAstronomers have opportunities at least twice a year to use partial, annular, or total eclipses of the Sun, or planetary transits, to interest the public in astronomy through their observations. It is important to provide accurate information about the pleasures and hazards of looking toward the Sun. The International Astronomical Union helps by providing knowledgeable information from experienced eclipse observers.

AbstractI summarize total solar eclipses that will occur during the 1990s, as part of the coordinating task of the Working Group on Eclipses of the International Astronomical Union. These eclipses will provide several favorable opportunities to provide coronal and other solar observations not only for intrinsic data reduction but also to compare with observations obtained from a variety of spacecraft.

The Chairman, W. Fricke, President of Commission 4, opened the Joint Discussion by drawing attention to the purpose and proposed procedure for the meeting. The Joint Discussion had been arranged by the Executive Committee of the Union in order to avoid the necessity for separate discussions by each Commission that was affected by the Report of the Working Group on the IAU System of Astronomical Constants. The Organizing Committee therefore proposed the following resolution:‘The members of the IAU at this Joint Discussion recommend to the Executive Committee that the following resolution be put before the General Assembly: “The International Astronomical Union endorses the final list of constants prepared by the Working Group on the System of Astronomical Constants and recommends that it be used in the national and international astronomical ephemerides at the earliest practicable date.’”

AbstractIn the past few years, the Philippines has been gradually developing its research and educational capabilities in astronomy and astrophysics. In terms of astronomy development, it is still lagging behind several neighboring Southeast Asian countries such as Indonesia, Thailand and Malaysia, while it is advanced with respect to several others. One of the main issues hampering progress is the scarcity of trained professional Filipino astronomers, as well as long-term visions for astronomy development. Here, we will be presenting an overview of astronomy education and research in the country. We will discuss the history and current status of astronomy in the Philippines, including all levels of education, outreach and awareness activities, as well as potential areas for research and collaborations. We also discuss issues that need to be addressed to ensure sustainable astronomy development in the Philippines. Finally, we discuss several ongoing and future programs aimed at promoting astronomy research and education. In essence, the work is a precursor of a possible white paper which we envision to submit to the Department of Science and Technology (DOST) in the near future, with which we aim to further convince the authorities of the importance of astrophysics. With the support of the International Astronomical Union (IAU), this may eventually lead to the creation of a separate astronomy agency in the Philippines.

Asteroids 1 Ceres and 4 Vesta are the two most massive asteroids in the asteroid belt, with mean diameters of 946 km and 525 km, respectively. Ceres was reclassified as a dwarf planet by the International Astronomical Union as a result of its new dwarf planet definition which is a body that (a) orbits the sun, (b) has enough mass to assume a nearly round shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a moon. Scientists’ understanding of these two bodies has been revolutionized in the past decade by the success of the Dawn mission that visited both bodies. Vesta is an example of a small body that has been heated substantially and differentiated into a metallic core, silicate mantle, and basaltic crust. Ceres is a volatile-rich rocky body that experienced less heating than Vesta and has differentiated into rock and ice. These two contrasting bodies have been instrumental in learning how inner solar system material formed and evolved.

I feel very honoured at having been asked by the IAU Executive to present Prof. Sagdeev’s invited discourse on Venus in his absence. As has already been mentioned Prof. Sagdeev was summoned to the talks between the USSR and the USA in Geneva as an expert in Space Research. He went there with several very important proposals for future cooperation in scientific exploration of outer space and we all hope that the results of his mission will be beneficial for the development of space astronomy and therefore for the whole astronomical community represented by the International Astronomical Union. I am sure that all present in this room realize that it is not an easy task to present someone else’s lecture especially at such short notice and in a foreign language. Besides, it is my opinion that a talk on Venus – the brightest celestial body in the sky except the moon and the Sun – Venus which always has been the symbol of beauty, love and femininity, that such a talk should surely be given by a man.

AbstractStandards of Fundamental Astronomy (SOFA) is an International Astronomical Union (IAU) service that provides accessible and authoritative algorithms and procedures that implement standard models used in fundamental astronomy. This paper summaries the current status, noting the changes during 2009-2012, and discusses issues that may arise in the future.
