What GPS co-oridnates was she standing at when it happened?
Was she dead or alive at the time?

The Bible doesn’t indicate whether she was alive or dead upon her assumption. The Orthodox discuss the dormition of Mary, which suggests she physically passed away.
It is believed she died at Ephesus, as she was under the care and protection of St. John the Beloved.
As a widow, traditional dress would likely have been black. However, in the approved apparitions, she has appeared, at different times, in blue, white, and/or gold.
