Can psykers 'see' each other?

By Otter, in Rogue Trader

I can't find it the CRB and didnt find it on the forums.

Do psykers see or sense each other? For example, in LotE there are psykers on Vaporius and Dross that the PC's will probably encounter. We have a Astropath and a Navigator in our group (which I Gm). If no psychic ability is used (at a detectable level) do the psykers still sense or 'see' an aura or feel a pressence of the other?

Thanks

Those with Psynesence can sense someone else using a psychic power, but a psyker just sitting there cannot be identified as such without the use of a power or ability which specifically allows such. The Navigator power Gaze Into the Abyss or the Aura Reading for the Astropath (the basic ability from the Divination school) are the most common of these methods.

Thanks for the feedback, I was planning on going that route anyway so my NPC psykers are not shot on sight.

I was reading another post asking what supplements are recommended and Navis Primer is my next purchase.
