甚长基线干涉测量法（VLBI）于1964年由佛罗里达大学发起，使用磁带记录的强度干涉测量法在55公里的基线上以18兆赫的频率工作。这显然是第一个VLBI。由于来源不明，随后的观测采用了越来越长的基线。最长的基线是7900公里（在肯塔基州和智利之间）。初步结果表明，如果S-burst源是非相干的，则至少有一些源必须小于0.1″弧。
Very long baseline interferometry (VLBI) observations of the decametric bursts from Jupiter were initiated by the University of Florida in 1964, with a tape-recording intensity interferometry operating at 18 MHz over a baseline of 55 km. This was apparently the first VLBI. Since the source was unresolved, subsequent observations were made with progressively longer baselines. The longest baseline is 7900 km (between Kentucky and Chile). Preliminary results indicate that if the S-burst sources are incoherent, at least some of them must be smaller than 0.1″ of arc.
