Utilizando el programa informático sobre la predicción de las Perseidas publicado por Sky & Telescope nos informa que el máximo se producirá a las 18h. UT del 12 de Agosto, aproximadamente; debido a ello, realicé la observación la noche del 12 al 13 de Agosto.
Using the informatic program about prediction of radiant meteors published at Sky & Telescope magazine at July issue, we say us that maximum of perseids radiant would be at 18h UT at 12th August aproximality. By this I made the perseids observation during the night 12th to 13th of August.
La observación la realicé desde las 22h.12m. hasta las 4h.14m. (UT); con un total de 48 meteoritos observados y con unas buenas condiciones climatológicas a pesar de encontrarse la Luna en fase menguante y en la constelación de Aries, limítrofe con Perseus.
I began at 22h.12m. UT to 4h.14m. UT, with 48 meteors and very good atmospherical conditions but the Moon was situated at last quarter close to Perseus, at Aries constellation.
