Abstract:
This paper presents results obtained with the Jodrell Bank - IAC two-element 33, GHz interferometer, located at the Teide Observatory on Tenerife, which is designed to measure the level of the Cosmic Microwave Background (CMB) fluctuations on angular scales of 1\degr and 2\degr. The results, at the 68\%\, confidence limit, from a maximum likelihood analysis of observations taken at Dec +41\degr are $\Delta T_\ell=64^{+7}_{-7} {\rm\,\mu K}$ at $\ell =208 \pm 18$ and $\Delta T_\ell=56^{+5.5}_{-6.0}{\rm\,\mu K}$ at $\ell=106 \pm 19$. The contribution of possible foreground contaminants are considered.
