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.
Best Wishes,
Michael

We picked this quake up strongly on our AS-1, but now it has been
deleted by the USGS. Why would this be?

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 little…

An interesting pair of events (see attached image from the WLIN AS-1
station) from the Aleutian Islands of Alaska. Preliminary USGS
magnitudes are 6.3 and 6.5. The seismograms are very similar! Although
most large earthquakes are single events (with aftershocks following the
main shock), pairs of earthquakes (approximately the same size and
location and occurring within hours or days of each other), or even
triplets, are not uncommon.
