There was no minor planet at this location. The object is also visible on 6 images taken with the same equipment on 2018-06-02 and on 2018-06-03. Images available here : https://www.flickr.com/photos/econseil/41632971725/ This object is located very close to AT2017ixr, which exploded in December 2017 and could be another outburst of this nova.

There seems to be a new outburst of this transient since the end of May

Atel#11162 confirms the object as a classical nova eruption and a member of the Fe II spectroscopic class.
