Seems there were no minor planets in the vicinity. However, the fit order for your image (quality of fit) wasn't great. But the co-ordinates of the object are pretty close in the line below beginning "JOM001". The Julian date is correct. For the purposes of MPC identification, I used J65.
I didn't check against comets yet...
Here are the results of your search(es) in the requested field(s):
No known minor planets, brighter than V = 18, were found in the 50.0-arcminute region around the following observation:
JOM001 C2009 05 31.02222 20 46 06.59 +30 35 14.3 15.2 C J65
Number of objects checked = 433977
Explanatory Notes
The positions are J2000.0 and are "quick look" positions designed for identification, not the rigorous comparison of observations with theory.
Offsets, intended for use by supernova hunters, are given in arc-minutes as the coordinates of the parent galaxies are rarely given to arc-second precision.
The motions are in arcseconds per stated time unit (if minutes or hours) or degrees/day.
Right-ascension motions include the cos(Decl.) term.
The brief orbit descriptor is either:
the number of oppositions (if marked with `o'),
the arc-length in days (if marked with `d') or
`V' if it is a Generalized Väisälä solution.
Comets are listed regardless of how faint they are. No magnitude estimates are supplied for comets. The heliocentric distance, r, is displayed in the Comments column. Most comets more than 5 AU from the sun will be beyond the reach of most observers, but the information is displayed to enable identification should an outburst occur.
If you are requesting objects other than just planets and natural satellites, a count is displayed of the number of objects that were checked. If the count is less than 300000, then the file of elements used by this service may have been truncated and this fact should be reported.

OK. I corrected for the time. Here is the Object time and location (UTC and XXX is the location as you gave it. I've assumed 68.0m above sea level.):
JOM001 C2009 05 30.98056 20 46 06.53 +30 35 14.5 15.8 C XXX
Astrometrica is showing no minor planets at these co-ordinates. MPChecker is showing nothing either (see below). I checked TheSky6 pro - nothing there.
The only niggle I have is comets. I *think* I imported them correctly into TheSky but I may not have done. I don't do comets Perhaps there are others here who would know how to check? Would Heavens-Above do this?
Notwithstanding that, the odject's JD and location are as outlined in the MPC line above ending XXX. It was about mag 16.

Here are the results of your search(es) in the requested field(s):

As a follow up, another option is to see if anyone took images around the same time as you (give or take a day or two). That would help to create an orbit that might help in recovering the object.
Failing all of that, I can chance my arm with the MPML folks and see if they can help. But they can be a tetchy bunch
If anyone has anything to add (other observatories???) please do so. This is interesting.

The CLS filter tends to through up green fuzzy reflections with DSLR images which I have seen on on other forums
astrochat.co.uk/forum/viewtopic.php?t=10919
. This may be another example.
