 By 1907 , new university buildings completely surrounded the observatory ; dust from the construction <unk> meteorological instruments , and at night electric lighting made astronomical work impossible . The Meteorological Office decided to abandon the site and move to a new building at the north end of campus on <unk> Street , trading the original Observatory to the University in exchange for the new parcel of land . There was some discussion regarding what to do with the Cooke telescope , since the Meteorological Office had little use for this purely astronomical instrument . No other use was immediately forthcoming , and the telescope moved along with the Meteorological Office to their new <unk> Street Observatory .
