2021-09-13 – Fixing of discrepancies after last MPC monthly update
The discrepancies in the number of NEAs reported last week have been resolved and the involved objects have been subsequently removed from our database.
2021-09-06 – Discrepancies after last MPC monthly update
We have noticed some discrepancies in the available data from the MPC at the last monthly update, which make that the number of NEAs might not be fully reliable (a couple of hundred objects with very poor orbits were unexpectedly added to the list of NEAs). We are working on solving this issue in cooperation with MPC.

2021-03-17 – Release of a batch of NEA orbital solutions including non-gravitational forces
Non-gravitational effects have been taken into account for up to 102 NEAs and our portal is now providing orbital information including the estimation of A1 and A2 parameters for those objects. In most of the cases the parameter determined was A2, which is associated to the Yarkovsky effect. In a small number of cases the A1 coefficient, associated to the solar radiation pressure, was estimated.
2021-03-10 – Release of a new version of the NEOCC web portal
After many improvements and additions performed to the NEOCC web portal through the years, we are happy to announce the release of a brand-new version of our portal based on present web technologies.

2020-01-30 – Processing of the last MPC Monthly Update
Our Orbit Determination System has successfully completed the processing of the MPC Monthly Update released on 27th January and referenced to the 9th January. The processing of the MPC daily and weekly updates since that date has also been performed with success.
2020-01-22 – High latency in the portal response
For some days now the portal is presenting some high-latency and variability in the response time to the user requests. We are analysing the source of this problem and will try to fix it as soon as that is identified. We are sorry for any inconvenience caused by this issue.
2019-12-20 – Portal under scheduled maintenance
The NEOCC portal will be under scheduled maintenance on 23-12-2019 from 07:00 UTC for a few hours. During that period and even if our front-end will be active, some of the services will be unavailable due to a scheduled shut down of a our back-end service. We apologise for any inconvenience motivated by this situation.
2019-12-17 – Processing of the last MPC Monthly Update
Our Orbit Determination System has successfully completed the processing of the MPC Monthly Update released on 12th December. The processing of the MPC daily updates since that date has also been performed with success.
2019-12-12 – Solution of the problem in the "Search for Asteroids" functionality
For some days now the portal is presenting the expected response in the "Search for Asteroids" functionality, so we consider that the portal is back to normal operations.
2019-12-05 – Processing of the last MPC Monthly Update
Our Orbit Determination System has successfully completed the processing of the MPC Monthly Update released on 8th November. The processing of the MPC daily and weekly updates since that date has also been performed with success.
2019-11-28 – Problems in the "Search for Asteroids" functionality
For some days now the portal is presenting some erratic behaviour in the "Search for Asteroids" functionality. Such incidence makes that in some occasions the portal runs into a time-out situation that is reported to the user, whereas in other occasions the portal runs normally. So far the cadence of this problem is irregular, which makes it difficult to track. The issue is still under investigation.
2019-10-28 – Large update in the risk list
Currently, our portal's risk list is still read from NEODyS. This will change in the short time when the NEO Impact Monitoring system at ESA will be put in operation. It is noted that the risk list has been significantly updated due to a change in the error weighing model. That new model is described by Veres et al. 2017 "Statistical analysis of astrometric errors for the most productive asteroid surveys", Icarus, V.296, p.139-149. As expected, several NEOs previously in NEODyS risk list moved out while several others moved in, as a result of virtual impactors with impact probability close to the generic completeness level (i.e., the probability value such that all the virtual impactors with a higher impact probability cannot escape the detection) or considering the fact that the nominal solution might be moved considerably due to their poor observation set and lousy orbit.
2019-10-22 – Fixing of the Orbit Determination System
After the hardware failure reported in the last entry, the system has been fixed today and put back to nominal operation. Furthermore, the information in the portal is fully updated to current date.
2019-10-14 – Hardware failure in the Orbit Determination System
Due to a hardware failure in the Orbit Determination System identified after the maintenance performed some days ago, some parts of our portal are not available nor updated. These include at least: the close approaches information for specific objects, the generation of ephemerides, and some of the "download as text/CSV/Excel" buttons across the portal.
2019-10-11 – Maintenance of the OD system during the weekend
Some services will be unavailable from Friday afternoon until 10:00 on Monday (all times UTC). These include at least: the close approaches information for specific objects, the generation of ephemerides, and some of the "download as text/CSV/Excel" buttons across the portal.
2019-10-10 – Creation of automated data access page
New page with documentation on how to access part of the information in the portal in text-only format (instead of HTML) using automated processes has been released. The page can be accessed in the "Additional Information" submenu.
2019-10-03 – Processing of the last MPC monthly update
The system is processing the MPC monthly update dated August 27. While the processing is taking place, the available data are limited to the full moon of August.
2019-07-19 – Yarkovsky effect detection and updated impact hazard assessment for (410777) 2009 FD
New observations obtained during the 2019 apparition by various observers, including our own team with ESA's OGS telescope, allowed for a better determination of the orbit of (410777) including the Yarkovsky effect over its orbit. This improved orbit solution was taken to recompute the future impact possibilities: the chance of a collision in 2185 could be completely ruled out, while only a very low probability of an impact in year 2190 remains.
2019-07-18 – Creation of the System Status Log
We have decided to use our existing "System Status" web page to report a log of relevant updates and incidences in the portal services. The reporting is initiated today, but we have also included some recent past entries which are deemed relevant.
2019-07-17 – Removal of the threat of 2006 QV89 for September 2019
The virtual impactor for 2006 QV89 in September of this year has been manually excluded after negative observations taken from ESO's VLT. That solution has consequently been removed from the risk list. The object itself remains in the list, with the most relevant virtual impactor among the remaining ones being in September 2023.
2019-07-12 – Inclusion of the ephemerides generation service
A new service to generate the ephemerides of any asteroid in the database within a given time interval has been released. The service can be accessed in the "Ephemerides" tab page of any asteroid page.
2019-07-12 – Change of reference albedo for diameter estimations
The reference albedo to estimate asteroid diameters has been changed from 0.10 to 0.14 in agreement with IAWN agreements.
2018-11-13 – Asteroid orbital information now computed by NEOCC
Since today, orbit determination (OD) data presented in our portal are the result of the OD computations being performed at our premises with an improved version of the original NEODyS software dedicated to OD. Impact monitoring software is currently being migrated, thus the information regarding impact computations will still rely on NEODyS provided data.
