The colours are much fainter, and according to Aristotle, who claims to be the first observer of this phenomenon, the lunar bows are only seen when the moon is full.
In reference to their first observer they were formerly called " Stiebel's canals."
By the end of October the last Turkish regular had quitted Magyar soil, and, to use the words of a contemporary observer, one quarter of Hungary was as utterly destroyed as if a flood had passed over it.
The third and fourth bows are situated between the observer and the sun, and hence, to be viewed, the observer must face the sun.
