Very surprising, astonishing (9)

I believe the answer is:

startling

I believe this is a double definition.

'very surprising' is the first definition.
(I've seen this before)

'astonishing' is the second definition.
(I've seen this before)

(Other definitions for startling that I've seen before include "Causing shock" , "Extraordinary" , "Remarkable" , "Jaw-dropping" , "Surprising or alarming" .)

I've seen this clue in The Irish Times.
