From observations with the GMOS multislit spectrograph on the Gemini North telescope, we have obtained spectra for 39 globular cluster (GC) candidates in the Virgo giant elliptical galaxy NGC 4649 (M60), of which 38 are confirmed GCs. The clusters extend out to a radius of 260 arcsec (3.5 effective radii). We find no rotation of the GC system, with

The Gran Telescopio Canarias (GTC) project
The outstanding quality of the Canarian sky, protected by law, makes it feasible to install the largest telescopes in the world at the observatories of the Instituto de Astrofísica de Canarias (IAC), which has promoted the design and construction of the Gran Telescopio Canarias (GTC). The GTC is a high-performance 10-m class telescope to be

The GREGOR Fabry-Pérot Interferometer
The GREGOR Fabry-Pérot Interferometer (GFPI) is one of three first-light instruments of the German 1.5-meter GREGOR solar telescope at the Observatorio del Teide, Tenerife, Spain. The GFPI uses two tunable etalons in collimated mounting. Thanks to its large-format, high-cadence CCD detectors with sophisticated computer hard- and software it is

The grey behaviour of Saharan dust
Data for five continuous years (1984 to 1989) at the Teide Observatory (Izaña, Tenerife), obtained with a full-disc solar multi-channel photometer devoted to the detection of solar intensity oscillations have now been used for a detailed study of the extinction coefficient behaviour at several wavelengths (450-870 nm) under different atmospheric

The Ground-Based Observations in Preparation and Support of the Seismology Programme
A vast ground-based observational effort was launched several years ago in order to prepare the optimal selection of targets for the COROT seismology programme. The first objective of this ground-based programme was to characterize as completely as possible all potential targets of the mission, in particular to determine their effective temperature

The GTC: an Advanced 10 m. Telescope for the ORM
The Instituto de Astrofisica de Canarias (IAC, http://www.iac.es/) is promoting the construction of a segmented 10m Telescope to be placed at its Observatorio del Roque de Los Muchachos (ORM) in the island of La Palma, Spain. The Telescope scientific drivers are to achieve an outstanding image quality, to maximize the observing efficiency and to
