Visibility IV / V
Another comet 64P / Swift-Gehrels was also filmed as a short clear section on Thursday night. 10 of these were taken. a series of 120-second L exposures, no more weather would have been enough. Like Wirtanen, this comet also appeared quite large, about 10 minutes of arc. The picture clearly shows maybe two very close jets of material to the left, slightly downhill. Image size 18 'x 23'.
