Carmen Blasco LAEFF I am working at LAEFF and I am in charge of an outreach project called PARTNeR (Proyecto Académico con el Radio Telescopio de NASA en Robledo). This project allows high school and university students to access a 34m antenna located at NASA's satellite tracking station to perform radioastronomical observations. From the scientific point of view, I am working with Erik Kuulkers (he is my supervisor) to get the Master Thesis. We are studying RXTE light curves of Cygnus X-2 to find any feature that characterises the existence of dips (if we consider this object's inclination, dips should have been observed, but they have not).
