It was from this episode that I first learned about the eyewitness account of a lunar impact seen by Canterbury monks on June 18, 1178 which some researchers believe resulted in the formation of crater Giordano Bruno. This event was recorded in the chronicle of Gervase. Another topic covered in this episode was the Tunguska explosion of June 30, 1908. Some researches such as Bill Napier and Victor Clube have linked these two events together as being a by-product of the Beta Taurid meteor shower; both events coincided with a peak in that shower.
