This page contains a Java application that lets you watch MINOS data as it is collected. If you want to launch this in a standalone window, press the "launch" button.
What are you looking at? Most likely a cosmic ray muon which made its way all the way down through a half-mile of rock, a few seconds ago in real-time! (note that the timestamp of the event is listed in GMT, not your local time). MINOS sees one of these cosmic rays every couple seconds - if we were on the surface, these would happen more than 100,000 times more often, making it very hard to see anything else! If you check the "update every 10 seconds" the display will show you fresh events automatically.
If you want to see things other than cosmic rays, select something different than "Most Recent" from the drop-down menu. For example, you could see the latest neutrino from the NuMI beam, or the last multiple muon collected.
Click, drag, and spin the mouse wheel on the display - you can move around to look at it from different angles or zoom in on things. More control instructions are at the bottom of this page.
The old, two-dimensional web event display is still available if you are having java troubles. This page also has more detailed explanations of what you're looking at.

|-||Select type of event to see. The entry "Most Recent" contains the most recent event, the "Last Beam Neutrino" will show you the newest neutrino from the NuMI beam, etc. The refresh button will go see if there's a new one, or you can check the "Update automatically" box below.|
|-||Speed of the event animation. Try slowing this down, you can see the events drawn in the time order they really occured. Was the even coming down or going up?|
|-||Rewind, Play/Pause, Fast forward buttons|
|-||Orthogonal/Perspective view toggle|
Display filters. Uncheck these boxes to hide various features of the MINOS detector.
The "Info" box will display a coordinate grid and label the Fermilab and Canada ends of the detector.
