Portal incidence in the "Search for Asteroids" functionality

Rest of NEOCC system modules are functioning properly.

Log of system status/functionality changes

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.
2019-07-17 – 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.
