This is Waxing Gibbous Moon @ 84% of Full Moon.
As you can see, the Moon is visible during the day too (this picture was takes @ 3:30pm PST), meaning that the Shabbat can be announced in advance of the evening.
Interesting thing about Moon and its phases (at least half and full moon phases) is that they are visible from ANY point on Earth at ALL times. I believe God did this to make sure that no one messes with His calendar and to assure that all people of the Earth know when are His Moedim. Even during the day as this picture clearly shows.
