Abstract:
To welcome all of you, in ESO Headquarters and on our La Silla Observatory in Chile, to this festive dedication of our New Technology Telescope, is a pleasure and a privilege. This is one event on two continents. ESQ's two major sites connected by several electronic communication links. ESO's guests and ESO staff present and participating on a wintry afternoon in Bavaria and on a sunny summer morning at 2400 m, high in the beauty of the Atacama desert. We hope that technology will not fail us now, but if it does and we cannot hear and see each other. then still it will be a celebration, in two simultaneous parts, by people linked by their engagement for astronomical exploration.

On January 25, 1990 we at ESO were shocked and saddened by the message of Pierre Gharvin's death. President of the Observatoire de Paris and astronomy leader in France, Prof. Charvin always showed a deep interest in ESO affaifs and contributed through the years to the development or ESO's relations with astronomical institutes in his country.

Abstract:
The ideal location for an optical telescope, short of being in orbit, would be being magically suspended in the air, out of all ground-induced turbulence. Most observatories try the next best, a location on a steep peak or ridge, in the generally correct assumption that the abrupt rising of the mountain does not give the air flow the time and space to bring ground-induced turbulence on the telescope.

Abstract:
On March 25. 1969, an audience of more than 300 people: members of the ESQ Council, Government officials. representatives of AURA. CARSO, IAU and CERN. other guests and staff members of ESO were assembled in the large dome on La 5illa which years later would house the Schmidt telescope. They celebrated the completion of the first phase of the construction programme. Three years and one day earlier, the road to the summit had been dedicated and an extensive building programme then lay ahead. Now, the Observalory entered its full operational phase with the middle-size telescopes.

Abstract:
U, B, V, and R plates for a 10 deg x 10 deg area centered on star 45 Oph are analyzed. The detection and measurement of the data are described. The variable stars detected in this area are studied. Consideration is given to planetary nebulae, galaxies in a direction near the galactic center, and open and globular stellar clusters. The data reveal 621 red variable stars in field O; 1592 red variable stars in field A and D; and 1238 red variable stars in field B. It is noted that the observations are useful for the study of objects populating the galactic bulge.

Abstract:
The origin of the diffuse interstellar bands (DIBs) represents one of the longest standing unsolved problems in astronomy. Although it is weil estabIished that they originate in the interstellar medium, no convincing identification of the responsible agent(s) has yet been made. They could be produced by large molecules, e. g. the fashionable polycyclic aromatic hydrocarbons (PAHs), or by atoms adsorbed on interstellar grains. A search for DIB features in stars with circumstellar dust shells (CDSs), carried out twenty years ago, was unsuccessful. It was therefore inferred that the DIB agents are not present in the circumstellar environments of late-type stars. Since then sky surveys have been made in the infrared range and have revealed the existence of numerous red long-period variables, very often enshrouded inside dense CDSs; most of these objects are miras evolving through the asymptotic giant branch (AGB). There is growing evidence that these sources are among the main contributors to the replenishment of the interstellar medium. In these conditions the absence of DIBs in the spectra of late-type stars appears puzzling. With the new instruments and better detectors available today, it seems worth to readdress observationally this problem.

Abstract:
The system PHL 1222 = UM 144 = QSO 0151 +048, which is composed of a close pair of quasars with redshift equal to 1.91, is studied. The distance between the quasar image and its brightest companion is 3.3 arcsec. The characteristics of PHL 1222 that imply it is an interacting quasar pair are discussed. The total mass of the system is estimated as 1. 7 x 10 to the 11th solar masses.

Abstract:
We have obtained high spatial-resolution CCD images in a night 01 excellent seeing of two of the five globular clusters (Clusters No. 2 and No. 3) in the Fornax dwarf-spheroidal galaxy using the NTT with Ihe aim of extending their colourmagnitude (C-M) diagrams into their cores. The images, shown in Figures 1 and 2, were obtained with a high resolution RCA CCD (O.129" pixel^-1) using EFOSC2. The average seeing (FWHM) for Cluster 3 was O".46 while that of Cluster 2 was 0".58 in the Johnson V band. B band images were also taken. All exposures were of five minutes duration.

Abstract:
Professional and amateur astronomers all over the world are excited about the prospects of seeing a really bright comet during the coming months. A newly discovered comet, known by the name of the amateur who first saw it, is now getting brighter each day. Observations are made almost every night at the ESO La Silla Observatory and elsewhere in order to follow the development of the comet and also to try to predict the maximum brightness which the comet will reach by mid-April this year.

In the Messenger No. 57 of September 1989 a status report on EMMI was given at the start of the integration and test period. This period has now been concluded; at the time these lines are written the instrument is about to be packed and shipped to La Silla. The integration of the instrument in the ND Nasmyth room B will take place this spring. Installation at the telescope will take place as soon as the second adaptorlrotator of the ND is fully tested at the end of June and a first period of tests on the adapter is scheduled for July. We describe here some of the results obtained during the tests in Garching.

Abstract:
In the framework of the cooperation between NASA and ESA on the Hubble Space Telescope (HST) project the archiving of the science data have always been ranked high in priority. Not only will it be very difficult to apply for and obtain observing time on HST (as those who participated in the first round of observing proposal submission can confirm), the utilization and optimum exploitation of these very expensive data sets can only be achieved through archival research. This has been demonstrated through the very successful de-archival programmes operated by the IUE data archive.
