RELEASED CODE! STEREOB
 [an error occurred while processing this directive]  Last Updated: [an error occurred while processing this directive]

Use the following code that's written here.
Place the following in your cron file (only needs to be fetched once per day):

0 0 * * * /usr/bin/fetch -q -A -T 10 -o $YOURDIR/stereo.txt 'http://stereo.gsfc.nasa.gov/where/where_is_stereo.shtml' > dev/null


[where $YOURDIR is the variable set to your chosen directory,  which is set at the beginning of your cron file].
Caution! Cron and command syntax varies between *NIX versions - the above is from FreeBSD.



The PHP code is located here. It can be included using SSI.

FAQ
Q: Why didn't you calculate it from orbit injection?
A: The mathematics are complex and using the real STEREO site data seemed potentially more accurate.
Q: Is absolute calculation an option?
A: Yes, you'll see some commented-out key timeline variables for future use, if required.
