Abstract
We present the SONG network and its prototype node at Teide Observa-tory.
SONG (Stellar Observations Network Group) is an initiative to construct a globalnetwork of 1-m robotic telescopes to ensure continuous monitoring ([1], [2]). Themain scientific goals of the SONG project are asteroseismology of bright stars andfollow-up and characterization of exoplanets by means of precise measurements ofstellar surface motions and brightness variations.Two instruments are foreseen on a SONG node: (1) a dual-colour lucky imagingcamera; (2) a high-resolution (R ∼ < K.

First light of the prototype SONG node, SONG-OT, is foreseen by the end of 2011.The evolution and current status of SONG-OT is illustrated in Figure 1.
Building:
The removal of the STARE telescope, excavation and pouring of theconcrete SONG pier took place in October/November 2010. The SONG containerand dome support were installed in March 2011.
Telescope and dome:
Factory acceptance is scheduled for the end of October 2011.Installation is expected in November/December 2011.
Spectrograph and Lucky Imaging Cameras:
The instruments are developed andtested in Aarhus and Copenhagen, and are waiting for first light.
