Near-infrared JHKL photometry of more than 200 stars in the open clusters Tr 14, Tr 15, Tr 16, Cr 228, and Cr 232 in the Carina Nebula is presented. By comparing these results with the available visual photometry and spectroscopy, it is found that the intracluster reddening is characterized, except in Tr 15, by a 'normal' extinction law for lambda

Details are given about the operation of a two station network and of a new semi-automatic station which has recently been added. Comparison is made with predicted duty cycles. A possible way of quantifying the sky quality is also given.

Earth based multichannel photometry of integral sunlight has been obtained at Izaña (Tenerife) during 1984 - 1986. Power spectra of the solar luminosity variations of individual days show power in the 5 minute interval above noise at a level comparable to SMM data. When combining contigous days of data the signature of p mode solar oscillations

The authors review briefly the observational status of abundance determinations for those elements produced in the first seconds of a "standard" Big Bang Universe, showing that although [4He] and [D] appear not to be mutually compatible there is still room for reconciliation via astration of D, for values consistent with estimated [7Li]. New limits

The Instituto de Astrofisica de Canarias has two observatories on the Canary Islands; Roque de los Muchachos Observatory on La Palma and Teide Observatory, on Tenerife. In this contribution the authors explain the guidelines for the allocation of this observing time and mention some of the future plans for remote observing and control of the
