Wave normal directions of auroral hiss observed by the S-310JA-5 rocket are analyzed from the spin modulation data of electric field components picked up by a dipole antenna extended perpendicular to the rocket axis, and the angle between the wave normal direction and the rocket axis observed by the crossed loop antennas which are both perpendicular to the rocket axis. It is found that the wave normals were making large angles to the magnetic meridian plane, so that the ray paths tracing back to the source indicate an altitude which is not above 700km, when the electron and ion temperature are less than 800K. The electron density between 200km and 230km actually observed by same rocket showed a density gradient much less than that represented by the plasma temperature of 800K. This point will support our result for the source altitude of auroral hiss observed by rocket.
