ResumoWe have searched for a flux of axions produced in the Sun by exploiting their conversion to x rays in a static magnetic field. The signature of a solar axion flux would be an increase in the rate of x rays detected in a magnetic telescope when the Sun passes within its acceptance. From the absence of such a signal we set a 3\ensuremath{\sigma} limit on the axion coupling to two photons ${\mathit{g}}_{\mathit{a}\ensuremath{\gamma}\ensuremath{\gamma}}$\ensuremath{\equiv}1/M3.6\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}9}$ ${\mathrm{GeV}}^{\mathrm{\ensuremath{-}}1}$, provided the axion mass ${\mathit{m}}_{\mathit{a}}$0.03 eV and 7.7\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}9}$ ${\mathrm{GeV}}^{\mathrm{\ensuremath{-}}1}$ for 0.03 ${\mathit{m}}_{\mathit{a}}$0.11 eV.
