What Christians connected the Great Schism and Crab Nebula Supernova (1054 A.D.)? What Christians connected the occurrence of the Great Schism* and the Crab Nebula Supernova, which both occurred around the middle of 1054 A.D.?

This question is not about Christians speculating in astrology—a form of divination, which is unlawful foreknowledge of future events.**

This question is related to how Christians have applied Genesis 1:14,


  …let them [i.e., the stars] be for signs…


to the 1054 supernova—namely, how they saw the supernova as a sign, not of a future event, but of, for example, God's displeasure at the Great Schism.

* Also called the "Eastern Schism" or "East-West Schism"

** St. Thomas Aquinas defines astrology as when "one desires to foreknow the future that cannot be forecast by their [i.e., the stars'] means." (Summa Theologica II-II q. 95 a. 5, "Whether divination by the stars is unlawful?"). Basically, "to know with certitude future human actions" by means of the stars is unlawful because humans have freewill, which the influence of the stars cannot take away; "to foreknow those future things that are caused by heavenly bodies" is "neither an unlawful nor a superstitious divination." (ibid., corpus).
The Chicago Tribune has an article that proposes some theories on why the observation of the supernova went mostly unnoticed in Europe. The article mentions the significance of the date with respect to the Church:


  Another reason the lack of records of the supernova is so puzzling is that 12 days after it first appeared in the sky, the Christian church began its final East-West split into the Roman Catholic and Eastern Orthodox Churches. Astronomical events were believed to foreshadow developments on Earth, making it unlikely that the appearance of a new star so near the time of such a major event would go unrecorded.


This source seems to imply that the contemporary sources who might have commented were silent on the matter.

The connection, however, has not been lost on everyone. This letter on fivedoves.com relates the two events intimately, though perhaps presumptuously:


  In heaven, the Great Schism of 1054 AD is marked by a supernova explosion creating the beautiful Crab Nebula and witnessed visually by both Chinese and European astronomers. The supernova appeared visible to the unaided human eye during daylight hours in July 1054 at approximately the same time as the eastern bishops voted to remove themselves from communion with the Roman Bishopric.
