The Possible Comet Confirmation PagePlease ensure you are familiar with the notes at the bottom of this page.
The objects listed on this page may be comets. If you detect cometary activity please describe the appearance in your submission using COM lines. If you do not see cometary appearance, say so in a COM line.
IF YOU DO NOT DETECT CLEAR COMETARY ACTIVITY, DO NOT CLAIM THAT AN OBJECT IS A COMET.
We will be operating a "reputation based" system for judging whether claims are valid. If you report cometary activity for an object later shown to be asteroidal, you may find that future reports of cometary activity by your observing station will be ignored by the MPC.

Notes on how to begin your own astrometric program are available.
Please ensure that you have read the additional notes on the NEOCP (which are relevant to the PCCP).
Please do not report observations of non-NEOCP objects in the same message as observations of objects on this page!
Please report unsuccessful attempts to detect objects listed here that are NOT listed as `updated' or that have not been updated in the past 24 hours using the NEOCP Blog.
Please note that observations and orbits of objects accessible via this service are made available only for your personal use. They are not to be promulgated via any medium. The data are preliminary until they appear on an MPEC or MPS.
You can now access ephemerides for the variant orbits used in the uncertainty plots from the pages listing the offsets from the nominal solutions.
You are reminded that a cross-reference of designations that have appeared here previously is available elsewhere.
If none of these objects are within the capabilities of your system, check out the Dates of Last Observation of NEOs not seen recently (in R.A. order), the list of bright recovery opportunities, or the Spaceguard Central Node's Priority List for alternate useful targets.
