Pillars are quite common. After 22-degree ring, pillars are
the second common halo from with parhelia (sun dogs). In case
of Moon pillars are perhaps more common that moon dogs. Moon
pillar is also the halo form which can be seen by quite a
young or old moon (before first and after last quarter).
Be careful when looking Moon in low altitude, pillars are seen
more often you believe.
