We report the detection of a pair of dwarf galaxies at $z\!=\!0.30$ which maybe in the early stages of an interaction. Both galaxies have stellar masses of$<10^{9}M_\odot$, and display a projected separation of $\sim\!29$kpc and aphysical separation of $\sim\!240$kpc. Evidence of ongoing star formation hasbeen found in both galaxies, with neither one showing an enhancedstar-formation rate that would be expected if they were already interacting.One galaxy displays a disturbed morphology but shows ordered gas rotation,which may reflect a previous minor merger event in the recent history of thatsystem. The nearest spectroscopically confirmed neighbour lies at a distance of38Mpc. These results indicate that these dwarf galaxies have no neighbouringmassive galaxies, however with the data available we have been unable todetermine whether these galaxies are isolated in the field or belong to a groupof low-mass galaxies. As a detection of a rare dwarf-dwarf pair beyond theLocal Universe, this system provides an uncommon opportunity to explore theproperties of galaxy groups in the low-galaxy mass regime as a function ofredshift.
