Abstract : Synthesis observations of the 4830 MHz formaldehyde absorption originating near Sgr B2 have been obtained with a resolution of 20 arcsec in right ascension and 40 arcsec in declination. The velocity resolution was 3.1 km/s. The results suggest that there are at least two absorbing clouds near the source. One cloud has a velocity of 80 km/s and is associated with only one of the two bright continuum components. Another cloud, with a velocity of 65 km/s, overlies the entire continuum distribution. At a velocity of 50 km/s, there is some evidence that a third cloud covers the southernmost region of the source. (Author)
