Three different maps of the quiet Sun, observed with the Advanced Stokes Polarimeter (ASP) and the Diffraction-Limited Stokes Polarimeter (DLSP), show evidence of strong (~=1700 G) and weak (

Observations and modelling of earth's transmission spectrum through lunar eclipses: A window to transiting exoplanet characterization
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

Observations of the 2001 Leonid meteor storm from northern Australia with the Teide imaging meteor system
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

Observations of the Crab Pulsar between 25 and 100 GeV with the MAGIC I Telescope
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

Observations of the Lensed Quasar Q2237+0305 with CanariCam at GTC
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

Observations of the phase differences between irradiances and velocity for low-degree solar acoustic modes
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
