Hi!

You mean for gravitational waves?

Well, the GW app is looking for continuous waves, most likely from spinning neutron stars, but would find continuous GW from any source if it is within certain parameters (frequency, rate of change of frequency, and strength of signal, of course).

To answer your question, the Gravitational wave detectors are non directional, that is they are not pointed to certain areas of the sky like radio of optical telescopes, they are more like antennas. Most of the searches done at E@H have been all-sky searches, that is a single such search will cover the whole sky, but will look only for sources with certain frequencies and frequency-decline rates.

So yes, the spot has been looked at already, but not necessarily with the latest detector data (S6 run, currently ongoing) and all frequency bands.
