Question regarding a cleric aura size (from glory domain)

[Jeon]

From Core (cleric glory domain): Divine Presence (Su): At 8th level, you can emit a 30-foot aura of divine presence for a number of rounds per day equal to your cleric level. All allies within this aura are treated as if under the effects of a sanctuary spell.....

My question is this: what is the size of this aura? Is it 30 ft radius from my character? Many other auras are a bit more specific but the cleric domain aura always have this wording.

Thanks for all responses

Looks like an auras given range defaults to radius unless otherwise stated.

The wording is a bit soft, but I think the 30 ft radius stays centered on the cleric. Allies not within the aura do not gain the benefit.

Glory Domain states: you can emit a 30-foot aura of divine presence

Under the Aiming a Spell:

Burst, Emanation, or Spread wrote:

A burst spell affects whatever it catches in its area, including creatures that you can’t see. It can’t affect creatures with total cover from its point of origin (in other words, its effects don’t extend around corners). The default shape for a burst effect is a sphere, but some burst spells are specifically described as cone-shaped. a burst’s area defines how far from the point of origin the spell’s effect extends.

An emanation spell functions like a burst spell, except that the effect continues to radiate from the point of origin for the duration of the spell. Most emanations are cones or spheres.

I think "emit" sure sounds like an "emanation", and so the 30-foot aura is a radius.
