The far ultraviolet (FUV) diffuse light detected by GALEX offers interesting information on the large scale distribution of Galactic dust, owing to the GALEX FUV band sensitivity and resolution. We aim to characterise the ultraviolet large scale distribution of diffuse emission in the Virgo direction. A map of this emission may become useful for various studies by identifying regions where dust affects observations by either scattering light or absorbing radiation. Description: The fits file provided are image of the diffuse ultraviolet light in the direction of the Virgo cluster. These mosaics were constructed in the context of the GUViCS survey. Individual observations in the NUV and FUV bands of the GALEX telescope were combined after subtraction of sources in order to focus on the contributions due to Galactic cirrus and zodiacal light. In NUV and FUV bands, mosaics were constructed on pixels of 1-arcmin size, starting from the All Sky Survey of GALEX. In the FUV band another mosaic was constructed with pixels of 20 arcsec size. They are expressed in units of counts s^-1^arcmin^-1^ squared.
