¶ Paired Doves
These glitches appear at low frequency, and look somewhat like chirps, but they alternate between increasing frequency and decreasing frequency. These glitches were identified by citizen scientists, and we believe they are related to 0.4 Hz motion of the beamsplitter at LIGO Hanford.
