#S20014 was found by an unmodelled burst search, I'm always skeptical of these, as they are easily confused with glitches
False alarm rate: 1 per 25 yr

#S20014 looks to be low frequency, it's central frequency is around 65 Hz

Extremely heavy black hole mergers could be in this range. These signals are short. They can be found by burst searches and missed by template searches (there's not much to match)

There are also short, low-frequency glitches. Here are examples of Blip and Tomte glitches from @GravitySpyZoo. This glitches are hard to identify, as we don't have a good auxiliary monitor to identify them
