i don't know anything about moon circumbulating the Kaaba and causing the sky to become blue. But a relative told me that a relative of hers had said that once when she was at the Kaaba at night, she had seen a blue light coming from the sky to the Kaaba and going back up again. The Kaaba is a place of great wonders. It's one place where there is no difference between day & night. People in Mecca go to the Kaaba all the time for Tawaf & Umra and the streets around the Kaaba are always filled with people and vendors. The place is also always lighted and has a noor effect. There is no darkness there. A trip to the Kaaba is very spiritually uplifting, enlighting. IF you can go there in the last days of Ramadan, then do so.
