Elevation 264 m Site classification: Rural. Conditions: About 20º C. Intermitent wind. Moon: not present Sky darkness: limiting magnitude 3.8 Telescope: 10" F/5 dobsonian reflector Eyepieces: 25mm Sirius Plosll / 10mm Sirius Plosll / 3x achromat Barlow lens `Magnification:` 50x , 125x , 375x				50x Looks like a common simple star. 125x Also looks like a simple star.. but sometimes a considerably fainter component appears for very short periods. The separation is small but when appears the components looks bairly touching with the primary star. It is very hard to evaluate the PA or separation in these conditions. The component seem to be in NNE from primary. Primary seemed a little blue in color. 375x nothing in plus.
