What was with the moon last night?

How high above the horizon was the moon when it was yellow? Ash from Mt.Redoubt high in the atmosphere may be the reason, Some one in the UK said the moon looked like it was on fire, Refraction of moonlight when it''s close to the horizon often makes the moon have a red, orange, or yellow tint, but I suspect that is not what either of you are talking about. I'm in central OK and the moon was white last night about half-way up from the north-west horizon.
