This issue of the Bulletin of the Spanish Astronomy Society welcomes, for the first time, a special edition dedicated to a project: the ALHAMBRA mapping. At the same time that the Bulletin sees the light, once again coinciding with the summer solstice, the first set of data is released for the national community (the ALHAMBRA Gold Sample), and in particular for the ALHAMBRA Extended Team, in which you are included a large part of the members of the SEA.
We include a series of short articles dedicated to the scientific, technical, and even historical aspects of the project. Some of them have already been published in professional journals, or are in different phases of the submission process. Others show the lines of work of some of the research groups within our team.We hope that the articles encourage you to know the data, to use it and, if you wish, to contact us to join the work. We also take the opportunity to announce that between November 12-14, 2013 an open meeting will take place in Granada, to make the complete presentation of the catalogs and data. You are, of course, invited to attend.
Many years of work have been dedicated to the design, acquisition and treatment of data by the ALHAMBRA Core Team, led by Mariano Moles. But it has not only been the product of human effort, but also of the granting of a large number of nights of observation in the 3.5-meter telescope of the Centro Astronómico Hispano Alemán in Calar Alto.This concession was made possible thanks to the modification of the agreement between Spain and Germany, approximately 10 years ago, by which our community used 50% of the available observation time. In these moments when a new modification endangers the very existence of the Calar Alto Observatory as we know it, we believe that these data and all the science that we can extract from them represent our best tribute to the Observatory, to its staff,
