Light pollution in Spain. An european perspective

Using DMPS satellite night images taken in 2000 we have estimated the saturated surface in many European countries. The objective of this study is to compare the illumination conditions and its effects in light pollution. We have measured the surface of the saturated zone. We compare this parameter with the ratio of population density of the country. To avoid bias, normalize by dividing the area built in each country prior to the comparison. In this way only takes into account the surface that really makes sense to illuminate. We have gathered the official data on energy consumption in public lighting in Spain. After plotting the evolution along the years we found changes in the way this value is obtained in different provinces of Spain and we made a more pessimistic prediction for the present energy consumption

Proyectos de ASAAF-UCM observando con PARTNeR

Conjunto de actividades formativas realizadas desde la Asociación ASAAF-UCM con el radiotelescopio del Proyecto PARTNeR, entre las que se incluyen: Elaboración de un proyecto científico propio, creación de un software propio de reducción automática de datos, presentación de resultados en congresos temáticos y revistas de divulgación

Estudio fotométrico diferencial de la emisión luminosa al espacio por parte de los países de Europa occidental

En este estudio se proponen una serie de indicadores para la evaluación de la contaminación lumínica de ámbito estatal. Esta conclusión resulta del análisis de la emisión luminosa al espacio procedente de Europa occidental. Para ello se han analizado con técnicas astronómicas las imágenes del NOAA (Satélites DMSP, banda OLS "VIS" band 0.40 - 1.10 um). Dicha propuesta incluye aspectos demográficos no tratados en otros estudios de la misma temática. Como contraste, se incluye una compilación de diversos indicadores de contaminación lumínica elaborados con información oficial de medios estatales y de la EU. También se trata la evolución del gasto en alumbrado público de España y su relación con las imágenes de satélite. Caso peculiar dentro de la muestra de países

Iluminación LED. Un arma de doble filo

La iluminación LED es el futuro de la iluminación. Sin embargo, como toda tecnología, puede usarse de manera correcta o incorrecta. En el caso de los LED, el abaratamiento de la producción de luz podría provocar un aumento descontrolado de la Contaminación lumínica. Por otro, el uso correcto de los LED podría ser la solución al mismo mal por su capacidad de encendido casi instantáneo.Depto. de Física de la Tierra y AstrofísicaFac. de Ciencias FísicasFALSEpu

The ASAAF-UCM project with PARTNeR

ASAAF-UCM (ASociación de Astrónomos AFicionados de la Universidad Complutense de Madrid), an amateur association with both, graduated and undergraduate students of Physics, is involved in PARTNeR. As a result of this work and several runs of obsevation, we present measurements related to the flux variations of SGR-A* at cm-wavelengths. The global educational research project of ASAAF-UCM also includes the development of a GPL sowtware to reduce and analyze the data

Orbits and emission spectra from the 2014 Camelopardalids

We have analysed the meteor activity associated with meteoroids of fresh dust trails of Comet 209P/LINEAR, which produced an outburst of the Camelopardalid meteor shower (IAU code #451, CAM) in 2014 May. With this aim, we have employed an array of high-sensitivity CCD video devices and spectrographs deployed at 10 meteor observing stations in Spain in the framework of the Spanish Meteor Network. Additional meteoroid flux data were obtained by means of two forward-scatter radio systems. The observed peak zenithal hourly rate was much lower than expected, of around 20 meteors h(-1). Despite of the small meteor flux in the optical range, we have obtained precise atmospheric trajectory, radiant and orbital information for 11 meteor and fireball events associated with this stream. The ablation behaviour and low tensile strength calculated for these particles reveal that Camelopardalid meteoroids are very fragile, mostly pristine aggregates with strength similar to that of the Orionids and the Leonids. The mineral grains seem to be glued together by a volatile phase. We also present and discuss two unique emission spectra produced by two Camelopardalid bright meteors. These suggest a non-chondritic nature for these particles, which exhibit Fe depletion in their composition

Thanks goes also to Francisco Ocaña and Jessica Starkey for the critical review of this text.We present the results of the analysis of satellite imagery to study light pollution in Spain. Both calibrated and non-calibrated DMSP-OLS images were used. We describe the method to scale the non-calibrated DMSP-OLS images which allows us to use differential photometry techniques in order to study the evolution of the light pollution. Population data and DMSP-OLS satellite calibrated images for the year 2006 were compared to test the reliability of official statistics in public lighting consumption. We found a relationship between the population and the energy consumption which is valid for several regions. Finally the true evolution of the electricity consumption for street lighting in Spain from 1992 to 2010 was derived; it has been doubled in the last 18 years in most of the provinces.
