Lovely colour - but not Holmegaard, as far as I know, and definitely not an Arne (later renamed Provence) series bowl. Arne series are of a much thinner glass, have pushed-in bases, and the rims are inverted.
This better-illustrates the series than my own attempt: http://www.holmegaard.com/web/eng/wm3.asp?id=133EDIT:
Just had a second look at your photos - is the rim inverted on yours? At first glance it just looks like very thick glass, but on reflection I'm not not sure. But I think the base-finish, either way, discards Holmegaard from the running.
