During the eclipse on 14th-15th April 2014, these parameters were measured with a photometer and a weather station. The obtained results allow the comparison, practically, of the optimal conditions for observational astronomy work in the Tatacoa desert and, therefore, to certify it as suitable place to develop night sky astronomical observations. This investigation determined, to some extent, the suitability of this place to carry out astronomical work and research within the optical range. Thus, the changes recorded during the astronomical phenomenon allowed the classification of the sky based on the Bortle Scale.]]></p></abstract>

Durante el eclipse del 14 y 15 de abril de 2014, estos parámetros se midieron por medio de un fotómetro y de una estación meteorológica. Los resultados obtenidos permiten hacer comparaciones de manera práctica sobre las condiciones óptimas para el trabajo de astronomía observacional en el desierto de la Tatacoa (Colombia) y así catalogarlo como un lugar apto para realizar observaciones astronómicas nocturnas. Esta investigación permite determinar, hasta cierto punto, la idoneidad de este lugar para llevar a cabo trabajos astronómicos e investigaciones dentro del rango óptico. De esta manera, los cambios registrados durante el fenómeno astronómico permitieron la clasificación del cielo con base en la escala de Bortle.]]></p></abstract>
