Observations of the WMAP sources were made using the AMI-SA during 14 separate observing runs between 2007 April and 2008 September. Observations of the WMAP sources using VSA were performed during 10 separate observing runs between 2007 February and 2008 July. (1 data file).

In this paper we describe in detail the implementation and main properties of a new inversion code for the polarized radiative transfer equation (VFISV: Very Fast Inversion of the Stokes Vector). VFISV will routinely analyze pipeline data from the Helioseismic and Magnetic Imager (HMI) on-board of the Solar Dynamics Observatory (SDO). It will

Multi-object spectroscopic observations of A2294 were carried out at the TNG telescope in December 2007 and August 2008. (1 data file).

We observe Eris, one of the largest trans-Neptunian objects, in the 300 - 2480 nm range with X-Shooter, the first second-generation instrument for the ESOVery Large Telescope, and compare the newly obtained spectra with those available in the literature. The large spectra coverage and high resolving power ( / ' 5000) of X-Shooter allow us to study

Spectroscopic observations during a low state of BB Dor reveal a complex emission distribution. Irradiation by the white dwarf as well as magnetic fields of the secondary star are needed for an explanation.

We have taken advantage of a stellar occultation by the dwarf planet Makemake on 2011 April 23, to determine several of its main physical properties. We present results from a multisite campaign with 8 positive occultation detections from 5 different sites, including data from the 8-m VLT and 3.5-m NTT telescopes in Chile, which have very high
