No. 125.\\ The detection was made employing the ALMA Band 4 Science Verification data of IRAS 16293–2422 around 146 and 157 GHz. The number of unblended to moderately blended lines appears to be sufficient.\\ \\ In their work on\\ **[[https://doi.org/10.1051/0004-6361/202558316|Expanding the C3H6O2 Isomeric Interstellar Inventory: Discovery of Lactaldehyde and Methoxyacetaldehyde in G+0.693−0.027]]**\\ //Astron.

McGuire, S. Martín, M. A. Requena-Torres, B. Tercero, P. de Vicente, L. Kolesniková, E. R. Alonso, E. J. Cocinero, J. C. Guillemin, and I. Kleiner\\ also report the detection of hydroxypropanone, also known as hydroxyacetone, in the course of a molecular line survey of this cold, shocked molecular cloud near Sagittarius B2 and in the Galactic center region. Several transitions with good signal-to-noise ratio (S/N) between 32 and 102 GHz were (essentially) unblended. The authors provide column density raios of the C<sub>3</sub>H<sub>6</sub>O<sub>2</sub> isomers.\\ \\ ---- Contributor(s): H. S. P.
