You can use this on-line site to compute the expected arrival times of
various phases to your station:
This can help in interpretation.
Also, once you have saved the seismogram in .sac format you can use
AmaSeis as an analysis tool.
For my recording (also using a SEP instrument) I entered both my station
coordinates and the coordinates of the earthquake into AmaSeis and the
display header now includes the distance to the earthquake.
AmaSeis allows the seismogram to be placed on a travel-time graph, which
helps in identifying phases. In this case the P arrival is in the
shadow zone from the core but PP comes in strong.

With the help of this list I managed to make a lowpass filter at 0.5
Hz and I also got various tips for improving the case. I got it
and running in an improved state yesterday and all was set for a
to test it.
I noticed some pretty strong distortions beginning 11:52 UTC today
picking up a lot about 12:24. I checked
there was a
6.7 quake off India at 11:40, which I presume is a candidate.
location is Oslo, Norway.
Since I'm totally new to seismology, would anyone on this list
on the plot that my seismometer produced, does it look like a quake
and does my seismometer seem to work properly?
Here's a plot of the incident:
