a favourable sign, or acting with the support of somebody
auspice - omen
The word ‘auspice’ has two main uses. Firstly, if you are authorized by somebody to do something, even if you are not their employee, it is said that you are acting under their ‘auspices.’ In this context, it is used in the plural. ‘Auspice’ can also be used to describe a favourable omen or sign. However, the word 'auspicious’, which is derived from this meaning, is used much more commonly in this context.
