Why did Europe barely record the supernova of 1054?

On 4 July 1054 Chinese astronomers saw a 'guest star' near Tianguan (zeta Tauri) at dawn, visible by day for 23 days and at night for nearly two years; its remnant is the Crab Nebula. Japanese and Arabic sources also record it. Latin European chronicles are almost silent, in the year of the Great Schism. Was it badly placed for Europe, or did Europe simply not write such things down?

Base rate (25 October 2026): European chroniclers recorded only about 4 or 5 of the 11 comets China recorded in the 11th century, and only 1 of the 3 medieval supernovae. The 1054 silence is what that rate predicts; there is no special mystery to explain.
