In a few hours at 0:17 UTC on September the 28th 2015 you can observe the rare event of a super blood moon in many parts of the word. A super blood moon is a combination of a total lunar eclipse (which always goes together with a full moon) and a super moon event where the moon appears bigger because it is almost at its nearest distance to the earth.
If you don't want to miss these events in the future I have 3 apps for you:
1. Moon Phases (for the full moon)
2. Lunar Eclipse
3. Super Moon
For iOS you can get them all together in one pack (with 2 more apps):
