Abstract Results of three new balloon flights have recently become available concerning the galactic center electron-positron annihilation line at 511 keV. The groups involved were the University of New Hampshire, Durham, New Hamsphire; NASA Goddard Center for Nuclear Studies, USA; CEN Saclay, Gif Sur Yvette, France; and Bell Laboratories/Sandia Laboratories, USA. In these flights a “low” or “off” state was observed in the fall of 1981. Also, new evidence for a low energy “positronium” — like tail on the line has been obtained from a 1977 flight. These results are reviewed.
