Collected Information About Recent GRBs/GW_events/SGRs/Transients

1. Recent GRBs/GW_event/SGRs/Transients
2. Past GRBs/GW_event/SGRs/Transients (2018-1997)
3. Circular-by-Circular in serial number sequence

This page contains links to files of all the Circulars on the given GRB/GW_event/transient.
This includes the circulars published by the mission-instrument(s) making a detection,
and by the follow-up observers.

For each GRB/transient, the link label contains a series of strings.
These strings show which mission-instrument made the initial detection (the first to publish for simultaneous detections),
then zero or more strings showing which other mission-instruments made detections (in the order published), and
the "Optical" string if there were any ground-based optical detection(s) (or "optical" if only upper limit(s)),
"Radio" for a detection or "radio" for an upper limit observation(s), and
"z=n.nnn" for a redshift measurement.

Since this page and the linked pages herein are constantly changing, you should hit the RELOAD button every time you view it.

If there is no link to a recent burst, this is because the addition of the explicit link is done manually.
However, the file that the would-be link would point to IS created automatically. So, with a small effort
the savy web surfer can get to the file without having a formal link by just editing one of the other links
(shown in your 'location URL window' in your browser) to contain the new new burst date
(ie change the old 'yymmdd' field in the URL to the new burst's 'yymmdd'
(with an 'A' or 'B' etc suffix change as well) and hit reload -- note it is prefix-dependant: 'GRB', 'S', 'icecube_').
This 30-sec effort will get you to the recent burst's concatenated-file of all Circulars,
even before a slow human (such as myself) comes along to add the explicit link in this page.
