#S20014 was found by an unmodelled burst search, I'm always skeptical of these, as they are easily confused with glitches

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)
Supernovae are one of the targets of burst searches, but we expect those signals to be longer. #S20014f has a duration of just 0.01 s.
It has now passed initial data quality checks! More detailed analysis and checks are now underway (I wouldn't expect a Blip glitch to be identified at this stage, so I'll still take some convincing, but I'm a pessimist)

Since we don't know the source for #S200114f, we can't work out a distance, which makes optimising follow-up strategy extra tricky
1 Betelgeuse is still there
2 A few candidates found by SAGUARO🌵 (including @NUCIERA astronomers) gcn.gsfc.nasa.gov/gcn3/26753.gcn3 but nothing too exciting
3 Gravitational-wave analysis is still underway
