-Only three lines have been detected thus far of which one line may show partially resolved hyperfine structure. Therefore, the detection should be viewed with caution at the moment. Fortunately, the derived column density of about 1.5 ×10<sup>16</sup> cm<sup>–1</sup> with an uncertainty of a factor of 2 and the comparatively high single state temperature of 65 K should permit lines in the millimeter wave region to be detected fairly readily.+Three lines have been detected thus far with the 100 m GBT of which one line at 4.9 GHz probably shows partially resolved hyperfine structure.  
 +The proposed single state temperature of 65 K appears to be peculiar and may indicate non-thermal population.
