We discovered this minor planet about a week ago and have observed it 4 times now. One measurement came from our Taiwanese friends in Lulin.
The brightness changes within 1 hour by 1 mag as also can be seen here. The exposure in the center shows the MP at a brightness of 19.3 mag, the other exposures show it at 20.2 mag. The minor planet passed a galaxy cluster at this time.
