A graphical record of a cruciform appearance in the night sky and possible lunar-halo display of 806 CE in the Anglo-Saxon Chronicle is philologically traced back to mid-ninth-century continental manuscripts, and a probable observational site is identified as around Sens in France. Possible lunar halos are examined by numerical ray tracing. Cruciform halos are shown to be faint and rare and thus notable. Halos from physically credible cloud ice crystals reproduce the manuscript renditions.
