Abstract

The detection of Type I X-ray bursts is attributed to those seen by the Astronomical Netherlands Satellite (ANS) in September 1975 from the globular cluster NGC6624 containing the X-ray source 4U1820-303.

I revisit these X-ray bursts, by re-analysing data from the Soft X-ray Experiment (SXX) onboard ANS, which were stored on microfiche.

Earlier accounts of X-ray bursts had been reported; the first Type I X-ray burst recorded is the one observed by Vela 5B from Cen X-4 in July 1969.
