LVC Event Information


O1 and O2 era:
This page contains the Notices ONLY for the "G" and "GW" events that LVC has released to the public.
These G/GW events occurred during the O1 and O2 science operations intervals which was a private-phase mode of operation
(i.e. Notices were sent to only those sites that had an MOU with the LVC).
As the LVC publishes on each GW event, the Notices for that event are moved from the private portion of the GCN to the public portion.
(Please note that for the next science operation (O3, starting in early 2019), the Notices (& Circulars) are immediately public and distributed without the need of an MOU.)

Post O2 Further Release to Public:
Two of the four GW events mentioned in the Dec 01, 2018 press release have been moved to this public page: G296853(=GW170809) and G298936(=GW170823).

O3 era:
During ER14 and O3, the events released to the public will be prefixed with and "S" (for "Super events").


This page changes after each Notice, so hit your   <reload>   button NOW.


This table contains information about LVC Triggers and the potential Counterparts found in follow-up observations.
The most recent Notice is listed first (reverse time order).

The 3 left-most columns (EVENT) are the EventNumber and the date/time of the event.
These columns contain:
      the EventNumbers (assigned by LVC) (which is a link to all the original full-format email GCN/LVC Notices on that trigger),
      the Date (yy/mm/dd), and
      the Time (hh:mm:ss.ss) of the start of the event or the follow-up observation.

The next 14 columns (OBSERVATION) come from the results of the various observations and analyses by the LVC (or the Counterpart).
These columns contain:
        the NoticeType is Preliminary, Initial, Update, or Counterpart; Tests are not listed,
      the FAR (False Alarm Rate) specifies how often a trigger of this intensity would happen from just noise fluctuations,
      then for the CBC Triggers, the values of ChirpMass, Eta (mass ratio), and Max detectable Distance are given,
      then for the Burst Triggers, the values of Fluence, Central Frequency, and Duration are given,
      then for the Counterparts, the values of the RA,Dec location and the Intensity are given,
      then the URLs for the LPM (Location Probability Map) and the EVENT webpages are given (access requires login),
      then the Comments from the full-format email respective Notices.
The RA,Dec locations are in J2000 epoch. If a column's information is not available or is not applicable, then that entry is listed as "n/a" or left blank.
There are more fields of information than are shown in this Table;
please refer to the full notices in the links in the EventNum column.
