Description
We present 12 yr of monitoring of the gravitational lens Q0142-100 from
the Teide Observatory. The data, taken from 1999 to 2010, comprise 105
observing nights with the IAC80 Telescope. The application of the
δ2 method to the dataset leads to a value for the time
delay between both components of the system of 72 ± 22 days (68%
confidence level), consistent within uncertainties with the most recent
results. With this value in mind a possible microlensing event is
detected in Q0142-100.

Introduction Gravitational lenses are a powerful tool for Astrophysics and Cosmology. The goals of this project are: i) to obtain a robust determination of the Hubble constant from the time delay measured between the images of a lensed quasar; ii) to study the individual and statistical properties of dark matter condensations in lens galaxies from
