VISTA Science Verification (SV) observations were carried out on 15 nights between October 15 - November 02, 2009. The VISTA Galactic Mini-Survey (SVORION) is a deep ZYJHKs survey of ∼30 square degrees in the Orion OB association. The area is covered by 20 overlapping tiles. The secondary goal is the photometric monitoring of sources contained in one of the tiles.
