Information Project

This project had two principal objectives: to communicate safe methods to observe the Sun, so as to prevent ophthalmological accidents to people during the total solar eclipse of 3rd November 1994, and to collaborate with the primary school teachers in the science classroom, illustrating the classes, motivating the students to observe sky phenomena.In January 1993, a commission called “ECLIPSE 94“Executive Commission, of the Brazilian Astronomical Society was created to coordinate assistance with arrangements for observing the total solar eclipse of 3rd November 1994, that in Brazil was total in the western part of Paraná State, in Santa Catarina State and in a Rio Grande do Sul zone. Professional astronomers from Brazil and from several parts of the world were mobilized to observe this eclipse.

Support Students

Activation of pupils is an essential part of the teaching process within our schools. In this endeavour, teachers are not always successful, but in prevalent cases they are able to support students and pupils to read the offered work, which might not correspond with their area of interests by using various methods and approaches, and thus gradually broaden their horizons of their perception of the world around. To support the reading during the tuition, we may use variety of activation and motivation methods that shift teaching into the phase of an active engagement of pupils into the class work and beyond. Through a discussion, establishing of a problem or a possibility of alternating a literary work, or maybe other forms of work, a pupil moves from a role of a passive recipient of a piece of information to an active participant in the teachinglearning process. By this approach, not only the reading literacy is developed, but the communication and cooperation skills as well. Gestion to reading should be a priority especially for primary school teachers at the first degree. By their work (especially by an active differentiation) and their overview in the field of children´s literature, they can positively align their pupils in choosing a suitable book. Reading is the best way how to non-violently shape and positively influence the psychological and aesthetical development of children and young people.

The Spanish chronicles do not mention planets other than Venus, although they compare certain Aztec gods with classical gods such as Jupiter and Mars. Creation myths recorded by the Spanish chroniclers frequently name Venus gods, most notably Ehecatl-Quetzalcoatl and Tlahuizcalpantecuhtli. The focus on Venus seen in these texts is also mirrored in colonial period Aztec codices, which feature several Venus gods as rulers of calendar periods associated with the 260-day calendar. The famous Aztec Calendar Stone represents Venus symbols prominently in an image showing the predicted demise of the Sun in an eternal solar eclipse, to be accompanied by earthquakes. Venus is apparently seen as the cause of a total solar eclipse in the Codex Borgia, a pre-conquest codex from Tlaxcala, a community neighboring the Aztecs in central Mexico. Although no pre-conquest Aztec codices survive, the painted screenfold books attributed to neighboring communities in central Mexico provide evidence of the kinds of almanacs that were probably also found in Preconquest Aztec screenfold books. The Codex Borgia has two Venus almanacs associated with heliacal rise events and another focusing on dates that coordinate with events involving Venus and possibly other planets. A unique narrative in the Codex Borgia traces Venus over the course of a year, representing different aspects of the synodical cycle. The transformation of Venus in the narrative is evidenced by subtle changes in the Venus god, Quetzalcoatl, who represents the planet Venus throughout the synodical cycle. Another god, Tlahuizcalpantecuhtli (“lord of dawn”), appears in the narrative associated with Venus as the morning star and also is represented in a death aspect during superior conjunction. This is in keeping with Aztec legends that tell how the Sun killed Tlahuizcalpantecuhtli with his solar rays. The Borgia narrative also helps identify Xolotl as the planet Mercury and provides hints about other planets that may be linked with different aspects of Tezcatlipoca, an Aztec god who ruled the night sky.

Preliminary Account

An expedition to observe the total solar eclipse of August 30 having been sanctioned by the Admiralty, it was arranged, in concert with the Joint Permanent Eclipse Committee, that a party from the Royal Observatory should make observations at Sfax, a town on the north coast of Africa, about 150 miles south of Tunis. The programme of observations consisted of photographs of the corona on various scales for coronal detail and streamers, and photographs of the spectrum of the corona and chromosphere. The observers from Greenwich who took part in the expedition were Sir William Christie, Mr. Dyson, and Mr. Davidson. Professor Sampson, Mr. J. J. Atkinson, and Captain Brett, D. S. O., generously volunteered their assistance and shared the work of erecting and adjusting the instruments as well as of the observations on the day of the eclipse.

These observations are contained in a letter dated “S. S. 'Carnatic,' Suez, 28th August, 1868,” addressed to the Managing Directors, Peninsular and Oriental Steam Navigation Company. One of the hand spectroscopes sent out by the Royal Society had been entrusted to Captain Perrins; but as his ship at the time of the eclipse was about 20 miles north of the track of the total phase, he had no opportunity of using it for the observations contemplated. He thus describes the appearance at the time of greatest obscuration:— "That portion of the sun remaining uneclipsed consisted of a narrow streak (in shape like a crescent) of its upper left limb, in size about 1/16 part of its diameter. The light emitted from this was of a very peculiar description and difficult to describe, being at the same time extremely brilliant and yet most remarkably pale. The high sea running appeared like huge waves of liquid lead, and the ghastly paleness of the light thrown upon it and all around revealed a scene which, for its weird-like effect, it would be as impossible to depict as it is to describe."

Ground-based total solar eclipse observations are still the key method for coronal investigations. The question about its white-light degree of polarization remains unanswered. There are hypotheses claiming that the degree of polarization in certain regions of the corona may be higher than the maximal theoretically predicted value determined by Thomson scattering. We present polarization of the white-light solar corona observations obtained by three different teams during the March 29, 2006 solar total eclipse. We give an interpretation on how the polarization of the sky impacts brightness of the polarized solar corona, depending on the landscape during the totality. Moreover, it is shown that the singular polarization points of the corona are in linear dependence with the height of the Sun above the horizon.

This study is a part of doctorate research about the contributions of the continuous education of primary school teachers of mathematics in the Common National Curriculum Base. For such purpose, was established a discussion group made of 10 pedagogical supervisors of the early basic education city's municipal education system in the countryside of the Rio Grande do Sul/Brazil who could, during ten meetings, discuss, analyze and reflect over the proposal of the Common National Curriculum Base for primary school. At first, the participants of the group discussed over the Common National Curriculum Base proposed competences in the fields of mathematics. The article, therefore, discusses the concepts of a discussion group composed of primary school pedagogical supervisors about the general competences for elementary school presented on Common National Curriculum Base and its relations with mathematics. The group’s discussions were audio-recorded with the previous authorization of the participants. Through notes in the field researcher’s diary, the participants’ behaviors, inquiries, action, and reflections were watched and analyzed during the meetings. Although the group participants made consistent considerations about how to support student´s skill development it was found that some notes do not conform to the focus of competences or the participants do not realize that they do not apply to the learning process, that is to say, are focused on the student. This emphasizes the need for continuous education about the Common National Curriculum Base for the working early basic education teachers.

The One

In 1911, Einstein proposed that light bending by the Sun’s gravitational field could be measured during a total solar eclipse. The first opportunity in which this measurement would be tried was during the total solar eclipse of October 10, 1912. We report about the expeditions sent to Brazil to observe this eclipse, including the one from the Córdoba Observatory, from Argentina, which aimed to measure this Einstein’s effect.
