This Proposal has developed out of a previous balloon flight supported by NSF during which MeV X-rays were observed within the auroral zone in the afternoon sector. These observations were unexpected, though there have been few measurements taken in this local time and latitude sector which would reveal these phenomena. The present proposal results from decision by the NASA National Scientific Balloon Facility to again launch an arctic long duration balloon in the summer of 1998. It will be possible to refly the X-ray instruments on this flight. This will enable several weeks of continuous observations, motivated largely to search for additional MeV X-ray bursts in order to understand the significance and nature of these phenomena. The balloon observations will be made in conjunction with spacecraft observations, particularly the POLAR satellite which includes polar imaging instruments as well as plasma, wave, and field instruments. This proposal is primarily aimed as hardware refurbishment to enable the flight. A subsequent proposal will be submitted for analysis of the data. This proposal is being considered by both NASA and NSF and both agencies are undertaking the normal review process. Because, however, of the time critical needs for preparing flight instruments and integration into the balloon package, we have contacted reviewers to request an expedited review.

该提案已从NSF支持的先前气球飞行中发展，在此期间，在下午的Auroral区域内观察到MEV X射线。 这些观察结果是出乎意料的，尽管在当地时代和纬度部门几乎没有进行测量，从而揭示了这些现象。 本提案是由NASA国家科学气球设施在1998年夏季再次发射北极长时间气球的决定。 这将使几周的持续观察能够进行数周的持续观察，并在很大程度上搜索了其他MEV X射线爆发，以了解这些现象的重要性和性质。 气球观察结果将与航天器观测值一起进行，尤其是包括极性成像仪器以及等离子体，波浪和野外仪器的极地卫星。 该提案主要是用于实现飞行的硬件翻新。 随后的建议将提交用于数据分析。 NASA和NSF都考虑了这一建议，并且两个机构都在进行正常的审查过程。 但是，因为在准备飞行仪器和集成到气球套件的时间的关键需求中，我们已与审阅者联系以要求加快审核。
