Cripes. We get no GRBs for two weeks, and now we get five in three days. I've spent half my time at work reading burst alert emails and scrambling to keep up with who's observing which burst so I can update that page.
Sheesh. <GLP>It's like we're under attack or something</GLP>. 8)

Pretty cool. I just read this thread and went to the sonoma website. After refreshing the screen 2, maybe 3 times. POW! GRB 050715A shows up. Nice timing, or dumb luck, your choice. :wink:
Time for BA to start scrambling again. 8) |

And if the pattern holds I guess we may expect to see a slew of earthquakes pretty soon. Gsquare |

I'm not sure the last one (050717B) is real. I haven't seen any follow-up yet, and the data for it look suspicious. Sometimes these turn out to be false alarms.
Wait a few hours, and then check the description field on that page. I fill those out when I get solid info on the burst. Nothing so far on this last one.

Another thing I thought strange is that in the previous 7 GRB's (prior to this last one --7117B), four of them had a duration of exactly 70 seconds. Makes me wonder (what are the odds against that?) . Are these simply estimates, or maybe there is a reason for the correlation? --- :-k Gsquare |

Let me review-- no, that will take too long. Let me sum up.
When a GRB goes off, it may be detected by one of several satellites. When they detect it, they send an automatic alert to a "central command", if you will. This then automatically parses the info (strips out the observing satellite, where the burst is, and other pertinent info), and then sends out that alert to people who subscribe to the service. Our web page is one of those subscribers. It listens for incoming alerts, then grabs the info it needs. Within seconds of the alert being sent, the GRB is on our page. Later, usually in a few minutes or hours, updated notices are emailed by scientists who analyze the satellite data. There are also follow-up observations, and emails are sent about them. I read those, and then sum them up on the site. Swift will also make light curves, but those can take quite some time because they are done by hand by a guy at Goddard Space Flight Center. He sends them to me and I put them on our server for the page as well. Phew. And I left a lot of details off, too! |

GRBs occur in very young galaxies, right? I mean, if black hole in our galaxy "ate" something, it would of course give off lots of radiation, including gamma rays, but it wouldn't produce a GRB. Right? Or do I misunderstand something. |
