Old Novae: When New Becomes Old*

Despite their brightness at maximum, classical novae are very faint at
minimum light implying little or no follow up at all during quiescence.
In fact, about 3/4 of the 204 novae that erupted before 1980 still lack
spectroscopic observations or even an unambiguous identification of the
post-nova. We embarked on a project aimed at deriving the physical
properties of old novae decades after the explosion thus placing
post-novae in the framework of CV-evolution and being able to compare
the characteristics of the eruption with the characteristics of the
remnant. We present an overview of this project as well as preliminary
results.

The GTC/OSIRIS Data Reduction system

We present the online and the offline data reduction system for OSIRIS,
theoptical multi-mode instrument for Grantecan. The software is written
in Pythonand invokes IRAF tasks which have been optimized for the
instrument. Theflexibility of the software makes it easy to be adapted
to othertelescopes/instruments.
