Reciprocity failure with Ektachrome EIR (e.g., shooting under full moon)

This might be an odd question to ask, but has anyone experimented with shooting Ektachrome EIR at night under a full moon? My knowledge of reflected solar radiation from the lunar surface is that it continues well into the IR spectrum, trailing off only slightly to reflected visible light. So I guess this question comes in two parts:

1) How well, based on personal experience, does EIR hold up to long exposure times, in terms of reciprocity failure?

2) Has anyone here attempted to shoot EIR night shots under a full moon?

Thanks.

I have never attempted to shoot EIR under a full moon, but I have used it at evening/twilight at a balloon glow. Since that it the only time I have ever used it at night, I can only offer my observations. I will have to see if I can find that roll and scan a few.

That would be great to see. Thanks!
