I estimate the frequencies of gravitational waves from jittering jets thatexplode core collapse supernovae (CCSNe) to crudely be 5-30 Hz, and withstrains that might allow detection of Galactic CCSNe. The jittering jetsexplosion mechanism (JJEM) asserts that most CCSNe are exploded by jitteringjets that the newly born neutron star (NS) launches within few seconds.According to the JJEM, instabilities in the accreted gas lead to the formationof intermittent accretion disks that launch the jittering jets. Earlier studiesthat did not include jets calculated the gravitational frequencies thatinstabilities around the NS emit to have a peak in the crude frequency range of100-2000 Hz. Based on a recent study, I take the source of the gravitationalwaves of jittering jets to be the turbulent bubbles (cocoons) that the jetsinflate as they interact with the outer layers of the core of the star atthousands of kilometres from the NS. The lower frequencies and larger strainthan those of gravitational waves from instabilities in CCSNe allow future, andmaybe present, detectors to identify the gravitational wave signals ofjittering jets. Detection of gravitational waves from local CCSNe mightdistinguish between the neutrino-driven explosion mechanism and the JJEM.
