Recently we were able to retrieve the Earth's transmission spectrum through lunar eclipse observations. This spectrum showed that the depth of most molecular species was stronger than models had anticipated. The presence of other atmospheric signatures, such as atmospheric dimers, were also present in the spectrum. We have been developing a

We describe the Teide Imaging MEteor System (TIMES), a fully automatic experiment consisting of two fixed image-intensified video cameras which are operated from Teide Observatory (Tenerife, Spain). A second station equipped with an identical system is located in Maspalomas (Gran Canaria, Spain). TIMES has been designed to work with the MetRec

We report on the observation of γ-rays above 25 GeV from the Crab pulsar (PSR B0532+21) using the MAGIC I telescope. Two data sets from observations during the winter period 2007/2008 and 2008/2009 are used. In order to discuss the spectral shape from 100 MeV to 100 GeV, one year of public Fermi Large Area Telescope (Fermi-LAT) data are also

We present new mid-IR observations of the quadruply lensed quasar Q2237+0305 taken with CanariCam on the Gran Telescopio Canarias. Mid-IR emission by hot dust, unlike the optical and near-IR emission from the accretion disk, is unaffected by the interstellar medium (extinction/scattering) or stellar microlensing. We compare these “true” ratios to

Irradiance measurements from the IPHIR instrument flown on the Phobos 2 mission to Mars are used to derive phase differences and gains between broadband relative irradiance signals and full-disk velocity variations for l = 0, 1, and 2 mode with order ranging from 12 to 32. These data are compared with contemporaneous measurements of photospheric

We confirm recent results about the differences in temperature and magnetic field strength between the umbra of large and small sunspots. Five Stokes I- and V-spectra from the darkest cores of three different umbrae have been analyzed with the inversion code of the radiative transfer equation by Ruiz Cobo & del Toro Iniesta (1992). The run with
