Visibility III / V
Half past one I noticed a check on the situation and the show had clearly started and accordingly continued for at least half past two (window shots). Guessing in itself, but the duration of the show could have been well over a quarter longer at both ends. With the help of the driver, it was easily seen that the upper edge of the area between the northwest and the north only reached a height of 10 degrees (Fig. 3).
Edit. With the help of the driver, it was also seen that the area extended over the north to the northeast.
