SID data can be thought of as similar to seismograph data -- a tracking of signal strength over a period of time. The data format is little more than a timestamp and a signal strength value. These can be easily fed into Excel to automatically produce a graph such as:
Note the characteristic sunrise and sunset shapes. The 4 large peaks are events caused by solar activity.
For a tutorial on what to do with your SID data once you have extracted it from your monitor and sent it to Excel for graphical display, see:
Getting Started with SID Data by Shannon Lee (pdf)This includes information on how to confirm your data with that from the GOES satellite.

Stanford is hosting a centralized data repository where students' data can be automatically stored and retrieved. Numerous sites are already contributing data to this centralized site. The webpage also includes direct links to the GOES satellite that is directly monitoring solar activity.
