Our Lady of Zeitoun aka Our Lady of Light.
Accepted and affirmed by the Coptic Pope (not in communion with the Roman Pope) but it has stalled in the Roman Church:
The apparitions were confirmed by the Jesuit Father Dr. Henry Ayrout. Nuns of the Society of the Sacred Heart also witnessed the phenomenon and sent a detailed report to the Vatican, resulting in the arrival of an envoy on April 28 who also saw the apparitions and sent a report to Pope Paul VI.
It seems Bl Paul VI passed away before he ruled on the report, and subsequent Pontiffs have simply not continued the investigation.
I personally believe it, and the approval of Saint Pope Cyril VI is good enough for me.
Our Lady of Zeitoun, pray for us
