Analysis of bright features in 3840 ~ and Hc~ shows that for every Ellerman bomb (Hcc--0.9 ~) there is a cospatial brightening in the 3840 ]~ network. We give properties of these bright points in both wavelengths as well as describe: (1) the appearance, and subsequent separation, of new elements in the 3840 A network and (2) the direct transition from a 3840 ~_ bright point to a new sunspot.
