CommentThe comet is located in a bad direction for me; I have some trees in that direction, and even when I transported the old 20-cm scope (that I don't use much anymore) to a site away from the trees, the comet still rose above the highest point of the highest hill in the vicinity. Still, I managed to see it this morning, and it was not difficult.
