| Abstract: | Two flights from Alice Springs, Australia, were achieved in November 1977 and November 1978 with a plastic scintillator  -burst detector, effective area 6.3 m2, thickness 5 cm, energy response in the range 50 keV to 2 MeV. In 33 hr of good, high altitude data, two bursts were detected, yielding a rate corrected to an isotropic flux of
at a size of 8.5×10–9 erg cm–2. One event, seen at 22.14 on 15 Nov 1978, was confirmed by spacecraft measurements. The second, too small to be detected by spacecraft, arrived from 0 hr RA, –13.2° Decl. ±12° and possibly comes from a confirmed -burst source location. A galactic origin with a source distribution originating from a relatively thick disk, is favoured by these results. |
