Description
We report on an unidentified gamma-ray signal found in the region around the BL Lac object 1ES 0229+200.
It was recognized serendipitously in our analysis of 6.2 years of Fermi-LAT data at a distance less than $3^\circ$ away from the blazar.
The observed excess of counts manifests itself as an unexpected local maximum in the test statistic map.
Although several Fermi-LAT sources have been identified in this area we were not able to link them to the position of this residual signal.
A clear association with sources visible in other wavebands was not successful either.
We briefly discuss characteristics of this unresolved phenomenon.
Our results suggest a steep energy spectrum and a point-like nature of this candidate gamma-ray emitter.
