In preprint the Fermi Space telescope has recorded a gamma ray burst which is consistent with the LIGO result.
http://gammaray.nsstc.nasa.gov/gbm/publications/preprints/gbm_ligo_preprint.pdfUnfortunately the telescope wasn't looking directly at the event area at the time and so can only say the results are consistent.
In techno speak:
"The most likely location of GW150914-GBM falls within the likely location of the gravity wave source GW150914"
As discussed in future when events can be predicted both Ligo and the normal telescopes will be able to synchronize observations.
As the above shows even unplanned there is a high probability given the number of telescopes in operation that events from Ligo will be able to be directly confirmed. There is even a good chance as the other events of the first run are released they may be able to be matched to telescope observations.
The interesting part technically is that for a gamma ray emission to be made by the event there had to be matter close but still outside the black holes event horizon during the merger. If that is common then it is going to open ability for some sort of "x-ray" analysis of matter very close to a black hole during a merger which has got lots of scientists thinking about new space instruments.
