Several spectral line one-the-fly (OTF) projects were carried out during the summer semester. Although the observing mode is still experimental (making the active participation of an IRAM Granada astronomer necessary), very good results could be obtained. A number of software improvements were implemented over the past few months. The efforts to make this observing mode more user friendly continue. A memo describing the current capabilities, problems and limitations can be obtained from Hans Ungerechts (ungerech@iram.es).
