Slowly evolving, regularly spaced patterns have been observed in proton projection images of plasma channels drilled by intense laser pulses propagating in an ionized gas jet. The analysis suggests the formation of rows of magnetized soliton remnants, with a quasistatic magnetic field associated with vortex like electron currents resembling those of magnetic vortices.
