Upper limits of 0.5 mjy at 5 GHz and 4 mJy at 15 GHz have been obtained for the continuum flux densities of V645 Cyg. These low upper limits imply that any associated H II region must be extremely dense and compact, with angular size < 0.''06 and density > 3 × 10⁶cm. Alternatively, there may be a stellar wind associated with the star with a mass loss rate < 10⁵ 𝕸 ⊙ yr¹.
