Who observed it

Discovered by	F51 Pan-STARRS 1, Haleakala
Telescope	1.8-m Ritchey-Chretien + CCD
Usual observers	J. Herman, T. Lowe, P. Minguez, A. Schultz, I. Smith
Usual measurers	K. Chambers, T. de Boer, J. Fairlamb, H. Gao, M. Huber, C.-C. Lin E. Magnier, Y. Ramanjooloo, R. Wainscoat, R. Weryk

Names are the people who usually observe at that site, from Project Pluto's tables. MPC's astrometry records only the observatory code, never the individual, so these are not the observer of this particular object. Automated surveys list a telescope and no people.

Altitude through the night

In the staralt style: the object's altitude (solid) and the Moon's altitude (dashed), across dusk to dawn. The shaded band is the window pipeline.py judged actually usable; the red dashed line is the 20° floor below which MPC's normal fetch never sends a row at all.

Any remaining "no data" span is a real hole, not a bug: it means neither MPC's normal ephemeris nor the wider, floor-free fetch scoped to this plot returned a position for that stretch. The Moon's own curve is computed independently (it needs no orbit fit, unlike the object) and so stays gap-free even across a hole in the object's curve. Clock times are CET, local to the observatory — hover any point on the object's curve for UT and its exact separation from the Moon.

Every value NEOCP has reported for this object since neocp_history.py started polling — 5 snapshots so far. MPC's own confirmation page keeps no such record; this is built by polling it on a schedule and keeping every reading rather than overwriting the last one.

Drawn from MPC's own variant-orbit offsets, at the same epoch as their plot. Each orbit is one solution consistent with the observations so far; the ring marks the nominal position, and the field box appears only when it is comparable in size to the cloud.

Dot size shows how many variants share a position. MPC publishes these offsets rounded to whole arcseconds, so a tightly constrained object has thousands of orbits landing on a handful of grid points — their own picture is drawn from unrounded values and looks smoother. Sizing by count puts that density back rather than stacking invisible dots. Hover any dot for its share.
