Lunar Corona or Halo?

[sethoflagos]

This evening in London was dark, clear, still, and not too chilly (~8⁰C -ish) with a day-10 moon quite high in the southern sky.

It was surrounded by quite a bright diffuse pale disc about 10 lunar diameters across with a chestnut-coloured fringe. Google tells me that this is typical of a Lunar Corona.

However, what was even more striking was a rainbow halo (indigo to red outer) surrounding the corona maybe another 3 moon diameters wide which was quite intensely coloured for several minutes before it began to fade.

It's a long time since I had regular views of a northern sky so forgive me if this is commonplace, but can a luna corona and halo occur simultaneously?
