最近回顾了GBS0526-66在19791-2003年期间的观测结果，4主要是在它可能与大麦哲伦星云中的N49超新星遗迹相联系的背景下。然而，1981年和1982年的观测揭示了一种更复杂的行为模式，并表明1979年3月5日事件的这一来源的性质及其在太空中的真实位置远不清楚。金星13和14的观测显示，GBS0526-66继续产生微弱的经常性γ射线暴。因此，这个在3月5日爆发期间曾有几分钟表现为耀眼的X射线脉冲的瞬变天体，从那时起就表现出与硬X射线爆发的奇特相似之处。
The results of the observations of GBS0526–66 during 19791–3have been reviewed4recently primarily in the context of its possible identification with the N49 supernova remnant in the Large Magellanic Cloud (LMC). Observations in 1981 and 1982, however, reveal a still more complex pattern of behaviour and show both that the nature of this source of the 5 March 1979 event and its true position in space are far from being clear. Observations from Veneras 13 and 14 reveal that GBS0526–66 continues to generate weak recurrentγ-ray bursts. Thus the transient object which during the 5 March burst behaved for several minutes as a flaring X-ray pulsar1has since then been exhibiting a peculiar similarity with a hard X-ray burster.
