Abstract:
On February 13-15, 1995, a Workshop on the SL-9/Jupiter collision tookplace at the ESO Headquarters in Garching. More than 100 astronomers from all continents discussed the various aspects of this unique event, from the numerous multi-wavelength observations on the ground and in space to the subsequent difficult interpretation of the complex physical and chemical processes that took place in Jupiter's atmosphere. On page 19 of this Messenger issue, we bring the summary of the concluding round-table discussion. It reflects well the present status of the ongoing, hard labour by many groups around the world. While there has undoubtedly been significant progress within several areas, it is also obvious that it will still take quite some time before a coherent, detailed understanding emerges. The Workshop Proceedings are already at the printer and will become available by mid-April 1995. (See announcement on page 47.)

Abstract:
In a previous article ("Hunting the Bad Vibes at Paranal", Messenger No. 76 - June 1994), we described the approach followed by ESO to investigate the effect of microseismic noise on the VLT Interferometer (VLTI). In section 4 of that article, we presented a measurement campaign performed at Paranal to precisely characterise the natural microseismic activity in view of assessing its impact on the VLTI performance. At that date, only preliminary results were availableand presented. This article presents the final results of this campaign which provide the statistical characterisation of the micro-activity as seen from Paranal, as well as the evaluation of its impact on the stability of the Optical Path Length inside the VLT 8- m telescope.

Abstract:
After more than 15 years of intensive use, the Danish 1.54-m telescope on La Silla and its equipment are undergoing a majoroverhauI.Thegoal ofthis joint effort with ESO is to provide a more powerful research tool, updated to reflect changing scientific priorities. It will be armed with a couple of core instruments, permanently mounted and requiring a minimum of effort in operation and maintenance. On January 20, 1995, we passed a major milestone in the upgrade project with the installation of several new features, chief of which is the new DFOSC (Danish Faint Object Spectrograph and Camera), patterned after ESO'svery successful EFOSC instruments andequipped with a thinned Loral 2048 x 2048 CCD with exceptionally high quantum efficiency (QE). Also, a simple mirror cooling system was installed which will hopefully lead to an improved image quality. In this article, we briefly describe the DFOSC and its capabilities and our plans for the next steps.

Abstract:
The bulge region of our Galaxy contains a number of globular clusters whose study can provide important information about the history of the Galaxy formation conditions after the initial collapse of the spheroid. The age, dynamical and chemical conditions of the bulge are the crucial parameters to be investigated. Unfortunately, they are hardly observable in the optical wavelength due to the heavy extinction in the direction of the Galactic plane. For these reasons we have started a systematic study of a sample of metalrich clusters in the infrared using IRAC2 withe the new NlCMOS3 detector 256 x 256 pixels, mounted at the MPIIESO 2.2- m telescope at La Silla (Chile). Here, we present the results of combined visual and near-infrared photometry in one of the most metal-rich globular cluster NGC 6553 ([FeIH] - -0.2). The optical counterparts come from Ortolani, Barbuy and Bica (1990).
