Three Phases

The solar flare is discussed in terms of its three phases: energy storage, energy release, and dissipation. Some of the problems associated with theoretical modelling are considered, together with the limitations imposed by current observations. New measurements to be made by the N.A.S.A. Solar Maximum Mission satellite are expected to advance significantly our understanding of the flare mechanism.

Short Presentation

The X-Ray Polychromator (XRP) resumed operations on 24 April 1984 following the successful in-orbit repair of the Solar Maximum Mission Satellite. Since that time the two instruments that comprise the XRP, the Flat Crystal Spectrometer (FCS) and the Bent Crystal Spectrometer (BCS), have been used to obtain new spectroscopic data from active regions and flares. The FCS, in particular, has accumulated far more observations of soft X-ray line profiles than were obtained during SMM-I in 1980. For this short presentation, we have chosen two topics to illustrate the type of data that we have obtained since the repair.

By far the most significant event for Solar Flares as a whole over the past 3 years has been the operation of the Solar Maximum Mission Satellite, together with the accompanying data analysis, ground-based support and theoretical modelling. This has culminated in the series of SMM Flare Workshops, whose proceedings have now appeared (Kundu and Woodgate 1986 (I)), with chapters on a wide variety of topics which indicate the enormity and complexity of the flare problem.

The Times

ABSTRACTSome recent images taken by the white light coronagraph telescope aboard the Solar Maximum Mission (SMM) observatory show bright streaks that are apparently caused by particles associated with the spacecraft. In this report we describe these observations, and we analyze the times of their occurrence. We demonstrate that the sightings occur most often near SMM’s orbital dawn, and we speculate that thermal shock is the mechanism that produces the particles. Although these sightings have not seriously affected the coronagraph’s scientific operations, the unexpected passage of bright material through the field of view of sensitive spaceborne telescopes can lead to data loss or, in some cases, serious detector damage. The topic of space debris has become a significant concern for designers of both manned and unmanned orbiting platforms. The returned samples from the SMM spacecraft and the observations reported here provide a baseline of experience for future orbital platforms that plan long duration missions.
