Ah, there appears to have been some confusion. This attack occurred in the middle of the day. The vampires are wearing large and flashy suits that protect them from the sunlight, including face-masks. This is the reason the covenant was caught so off-guard.

Also, older and more powerful vampires are able to survive exposure to sunlight.

I realise I should have been more specific as to what time it was. My apologies for any confusion.
