James, You definitely should have recorded that Illinios quake. On the IRIS educational web page, sites all over the country from Arizona to Maine recorded it. Here is what mine looked like on April 18. Make sure the magnet isn't sitting on the coil.

Hi Jim, I am pretty sure that Mike Breed recorded it at CV. If he did and you didn't we should probably check out your instrument.

We picked this quake up strongly on our AS-1, but now it has been deleted by the USGS. Why would this be? Jay Jay Sinclair OESTA Chair Past President Michigan Earth Science Teachers Association sinclair@ida.k12.mi.us

Sue, I was with some friends when the piece on you came on Channel 9. They were all quite impressed both with the experience and how wonderfully you communicated what was going on. I was pleased to say I knew you!

This has been exciting in Illinois. The IRIS program got a lot of publicity on Friday. The local news station looked at the seismogram I have posted on the internet on our district website. They sent a TV crew and interview students. Another sent a crew and it the newspaper also did a story. I have installed the new dampering system that John Lahr sent. It does not appear to be as sensitive at the oil I used. Has anyone started to use it? Should I move the metal block back a litt... [more]
