The Solar system moves through the Milky Way galaxy with velocity of 230 km/s. The ecliptic plane is located ~60 degrees with relation to the galaxy plane, according to this source. The page also shows animated gif of the solar system motion through the galaxy (marked with "Image credit: Rhys Taylor), in which the galactical motion appears to be southwards (relative to the ecliptic plane). Direct link to the gif

On the contrary, the following image (borrowed from this answer on Astronomy SE) indicates solar system moves northwards relative to ecliptic plane: enter image description here

Question: If we wanted to send a probe in prograde galactical motion of the solar system, within the galaxy plane, would we need to direct it southwards or northwards relative to the ecliptic plane?
