5 Concluding remarks

1.

ISOSS 20246+6540 is a small isolated molecular cloud discovered by its 170 $\mu$m emission i the unbiased ISO Serendipity Survey.

2.

The globule appears as bipolar in both optical surface brightness and mm-line maps.

3.

A distance of 400 pc is likely, setting the diameter of the northern lobe to approximately 0.1 pc.

4.

The average physical parameters are: $T_{\rm kin}=11$ K, n(H₂)=7000 cm^-3.

5.

The population of small and faint starless globules can only be effectively explored by high sensitivity FIR measurements such as those carried out by PHT-C200 on board ISO.

6.

Our finding demonstrates the importance of such unbiased surveys by future missions like SIRTF, ASTRO-F or Planck.
