The 2012 Transit of Venus in Stellarium

Just in case you are clouded out, and no webcasts are working, here's a Stellarium script I made to show the transit of Venus as seen from Adelaide. It's in the new script language (which I have been working to make a guide too), so it's a bit obscure. I haven't done anything fancy (like labels or such). If anyone want me (say for classroom use) to I can add labels later. I have set it to zoom in so far because otherwise you can't really see Venus.

Anyway, copy the following script to a file called venus_transit.ssc, put it in the scripts folder, then run it through the scripts tab in the configuration menu. Enjoy!

core.setObserverLocation(138.59863, -34.92866, 10, 0, "Adelaide, Australia");
core.selectObjectByName("Sun", false);
StelMovementMgr.setFlagTracking(true);
core.wait(2);

// Zoom in on the Sun
StelMovementMgr.zoomTo(0.6, 2);
core.wait(2);

// Speed up the action
core.setTimeRate(250);

// When Transit over set to normal speed and zoom out

core.waitFor("2012:06:06T06:59:28");
core.setTimeRate(1);
StelMovementMgr.zoomTo(60, 2);
