Can a question directly modify a noun?


I was surprised by this sentence:

> 桜の花が今年いつごろ咲くか発表がありました。  
>  There was an announcement saying approximately when the cherry blossom will
> come out this year.

We seem to have a question 桜の花がいつ咲くか directly modifying a noun 発表.

If I'd been asked to say this I'd probably have said:

> 桜の花が今年いつごろ咲くか **という** 発表がありました

Are either/both of these grammatically correct? What about formality etc?

**Edit:** Just read [this
question](https://japanese.stackexchange.com/questions/30434/modifying-nouns-
with-question-phrases?rq=1) which seems to suggest that my modified sentence
is correct and that the original is wrong. But the original is from the NHK
news website, so I'd be surprised if it was wrong.




No, this 桜の花が今年いつごろ咲くか doesn't modify 発表 but the predicate.

か-ending clause has not only function as nominal clause, but as adverbial too.
Thus,

> 桜の花が今年いつごろ咲くか発表がありました。  
>  _An announcement was made on approximately when the cherry blossom will
> come out this year._

Of course, your rephrased version works too, but 桜の花が今年いつごろ咲くかという発表 could be
ambiguous whether it tells when they bloom or it literally says "when do they
bloom".
