The first results of the SOHO Joint Observation Program JOP 99 are outlined. JOP 99 involve several SOHO instruments (CDS, LASCO, MDI), together with TRACE, and two new ground-based instruments: HASTA (Hα Solar Telescope for Argentina) and MICA (Mirror Coronagraph for Argentina). The proposed program have a new motivation in taking advantage of the capabilities of the TRACE instrument, together with our experience in magnetic reconnection. The objective here is focused on the investigation of the conditions of the eruption of a prominence, often associated with the CME. JOP 99 is running at the moment that this abstract is submitted. It is a 5-days study of the filament/prominence, with 3-4 days observing the disk and 1-2 days observing the limb. While on disk, we will look for the eruption signatures in two ways: by studying the physical conditions in the filament and its surroundings (densities, temperature, abundances), and by looking at the magnetic topology changes. While at the limb, we will wait with luck for an eruption. If it does happen, LASCO and MICA observations will study if there exists an associated CME.
