The GTC Dome is entering into manufacture. Once the design has been frozen, it is time to expose the main features of the Dome and to exhibit the key aspects that will introduce an improvement on the GTC performance with respect to existing telescopes. The implementation of the natural ventilation for the telescope chamber, the use of an improved

The presentation summarizes the status of the first generation of instruments for the 10-m Spanish Telescope, GTC. The GTC is planned to have its first light at the end of 2002, and to be operating at the end of 2003. The management plan at the Project Office, PO, for the procurement of the instruments is presented.

ROSAT/HRI observations of the powerful radio-loud galaxy 3C 382 reveal extended X-ray emission associated with the source. On the basis of this new spatial component, a previous ROSAT/PSPC spectral analysis of the source is revised. Allowing for the presence of an additional thermal component in the PSPC spectrum, the non-thermal component is found

EMIR is a near-IR, multi-slit camera-spectrograph under development for the 10m GTC on La Palma. It will deliver up to 45 independent R equals 3500-4000 spectra of sources over a field of view of 6 feet by 3 feet, and allow NIR imaging over a 6 foot by 6 foot FOV, with spatial sampling of 0.175 inch/pixel. The prime science goal of the instrument

The ISOPHOT detectors were continuously exposed to high energy cosmic particles hits, resulting in an average hit rate frequency of an event per every 7 s. The net effect is a disturbance of the readout voltages, which decreases the signal-to-noise ratio and hence the photometric accuracy level. Thanks to the highly redundant readout method of

We analyse the new ISCCP (International Satellite Cloud Climatology Project) D2 cloud data to ascertain if a connection between cosmic-ray flux and cloud cover exists. Despite a previous finding that total-cloud factor and cosmic-ray fluxes were correlated, our results indicate that only the low-level cloud follows solar activity over the full
