Tempest is a period-4 oscillator that was found by Dean Hickerson in August, 1989 (4.0.3 in his oscillator stamp collection).

It first appeared in an asymmetric soup submitted to Catagolue by Rob Liston on February 9, 2020.

Hassling capabilities

In September of 1989, Hickerson discovered two ways in which multiple tempests can be used to hassle other small objects. Two tempests and two clocks can be used to hassle a Z-hexomino, and four tempests can be used around an object that resembles an equals sign. This latter object closely resembles sixty-nine, but has a lower kinetic symmetry of .frf compared to sixty-nine's nrv.

Information on this oscillator's commonness with respect to other naturally-occurring patterns is currently unknown.

Glider synthesis

A 19-glider synthesis was found by Jason Summers early on and is recorded in Mark Niemiec's database. It has since been reduced to 11 gliders.
