Apparently the first contact of the Epsilon Aurigae eclipse has been observed, according to this Sky & Telescope article. See also here.

The system comprises an F0 supergiant and a mysterious secondary that eclipses the primary every 27.1 years, with an eclipse duration of about 2 years. The secondary is thought to be a dust disk. What lies at the centre of the dust disk is unknown but may be a pair of B-type stars that clear out a central cavity.

I have read about this star while randomly browsing on wikipedia. It would be very interesting to see what is eclipsing the star.It also got a mention on the B.B.C's The Sky At Night here in the U.K.

I think it would be a very good excuse to use Hubble's Planetary Camera 3,like they did on Jupiter to find out what object that was the size of the Earth smacked into it ;)

I also hope one of the current big telescopes will be observing the event as well.

Epsilon Aurigae may be rather less extreme... Spitzer results seem to favour the low-mass scenario rather than the previously somewhat better-supported high-mass supergiant hypothesis.
