The new Galactic plane gamma-ray transient Fermi J0614+1713 was
observed with Fermi/LAT between 2022-01-28 and 2022-01-31
(ATel #15196, #15199, #15200). We imaged the field of
Fermi J0614+1713 with the NMW wide-field optical camera
( http://scan.sai.msu.ru/nmw/ ) between 2022-02-03 17:37 and
22:47 UTC obtaining 14x20sec exposures. We found no new source
brighter than V~15 in the vicinity of the LAT error circle after
comparing the NMW stack to the archival DSS-II Red image.
We also imaged the field of Fermi J0614+1713 with the 4.1m SOAR
telescope between 2022-02-02 05:31 and 05:45. Unfortunately,
the mosaicing was interrupted by passing clouds when only
a quarter of the improved Fermi error circle was covered.
No new source was found in the covered region down to V~19.
The hard X-ray emitting intermediate polar candidate
Swift J0614.0+1709 (Halpern & Thorstensen, 2015, AJ,150, 170) is
outside the area imaged with SOAR and below the NMW image limit.
