TLEs are available for this object. (Currently running to January 2020. By then, we'll probably get more observations.) Space-Track had TLEs for this object, but they involved the object being in low-earth orbit and were essentially works of fiction.

Jost Jahn was able to image this object in mid-March from (C95) ROTAT (click here for a timelapse video), with further data the next day from Masayaki Suzuki at (U69). Jost saw a possible light-curve of about 20 minutes, which would be unusually long for an empty booster. At the following perigee on March 30, Jost again got data on the object, and CSS swept it up the next day in the course of routine asteroid surveying.

(An update : Jost got another lightcurve on 2019 May 5.89 showing a period of either 623 seconds or 1246 seconds.

Since then, the object has been picked up by CSS a few times, and Jost has made some targeted observations. So the orbit has been quite well-determined since then.

With the new data, the effects of solar radiation pressure are now noticeable; we have a reasonably well-determined area/mass ratio and can say something about where the object will be over the coming year with a decent degree of confidence. The object is doing a good job of staying away from the moon; it got within about 85000 km on 2019 April 26, which will raise its perigee from about 100000 km to about 150000 km, increasing the orbital period from about 18 days to about 22 days. Unfortunately, I don't see it hitting the earth or moon in the next few years. (But it is an artsat, in a somewhat chaotic orbit. We may yet get lucky here.)

My initial orbit for this object was based on the first four observations (the ones made as the object was still going toward the moon) plus the knowledge that it had been near a perigee of about 200 km a little after launch time. This resulted in something close to a wild guess, though probably good enough over the short term that somebody could have observed the object if they had wanted to. It was the best I could do at the time; the Chinese space agency is very close-mouthed about where things are going.

In hindsight, my "guess" gave a perilune that was off by about two hours and a prograde pass; the actual lunar flyby was retrograde. As a result, the object ended up in a lower orbit than I expected (period of about 16 days, not 37). The orbital period has since increased by a couple of days due to lunar and solar perturbations.
