Click here for an explanation of pseudo-MPECs
This is a follow-up to an earlier pseudo-MPEC for this object from a few months prior to these observations, based on new data with the object recovered on NEOCP as A10WEWw.
There are a few comments about this recovery on the NEOCP Junk list., and an earlier post about its gradual decay from June 2023.
The residuals for the (113) and (033) observations are quite high. I think this is partly because the times are given to five decimal places; the object was moving at about 15"/second, and simply rounding the time to 0.00001 day introduces about 8" worth of error. If you observe this object, I'd suggest reporting the observation time to six places (or using ADES), and you should check your timing carefully.
But I also think that the drag at each perigee is varying. Peter Birtwhistle at (J95) got a light-curve on the object, showing a ~80-second rotation period and an amplitude of over a magnitude. I could easily imagine that the drag depends on the orientation of the object as it passes through perigee.
Not all observations have made it onto NEOCP (in particular, the ones without an 'NEOCP' reference were private communications). I don't think MPC is currently able to handle cases of this sort (and it is definitely outside the area they're charged with handling).

RA/decs are astrometric J2000 coordinates (corrected for light
time lag, but in the inertial J2000 frame, i.e., not rotated
for precession or nutation, and differential light deflection is
not included.) Display can be turned on/off in the 'advanced
options' for ephemerides. When turning them on, you can select
from various format choices (base-60, decimal, different
precisions, etc.)
Distances are in kilometers for distances under one million km
(about 0.00668 AU), and in AUs for larger distances.
The "SM" (Sun-Moon) flags consist of one or two letters, extended
from a scheme used on JPL's Horizons system. Letters used are :
* Daytime (sun above horizon)
C Civil twilight (sun below horizon, but by less than 6 degrees)
N Nautical twilight (-12 < sun's altitude < -6 degrees)
A Astronomical twilight (-18 < sun's altitude < -12 degrees)
m Moon is in the sky, less than 50% illuminated
M Moon is in the sky, more than 50% illuminated
l Object transiting in front of moon
L Object occulted by moon
a Below altitude/horizon limits set for the observing site
d Outside declination limits for your site/mount
e Outside elongation limits for your site/mount
h Outside hour angle limits for your site/mount
g Some galactic confusion
G Lots of galactic confusion
B Object is below the horizon
Uncertainties are one-sigma values shown in arcseconds (unless they
are very large, in which case they are shown in arcminutes or degrees).
In theory, the object should be within this distance of the nominal
RA/dec 67% of the time, within twice that distance 95% of the time,
and within three times that distance 99.7% of the time. In practice,
astrometric errors are not actually Gaussian, which means these
uncertainties are sometimes over- or underestimated. So you may have
to look farther, or not nearly as far, as the uncertainties say.
The object will probably be offset from nominal somewhere along the
indicated position angle, especially if the orbit is well determined.
Three-letter constellation abbreviations specify the constellation
containing that RA/dec, as defined by the IAU's 1930 delineation.
