Fun vacations for FIG Comet Arend-Roland with its long antitail. On April the antitail was degrees long. Image credit Armagh Observatory. The dream scenario for antitail development is a narrowly inclined and very productive comet making one of its irst perihelion visits. For example, Comet Lulin in had an inclination of degrees, that is, less than degrees from the ecliptic plane, and sported an antitail spike for two whole months, although most of the time this was not visible to the naked eye fig.
