The Tetrad IS a VERY rare event!! 4 blood moons in a row-with nothing in between! It's happened when Christ died and 2 other modern occasions.
The the modern Isrealites are watching this runup with this a silent expectation. The fact that there is a FULL SOLAR ECLIPSE, as well, right in the middle of the 4 blood moons? This will never happen again for 500 hundred years. The Bible says that there will be Great Tribulation BEFORE the "Sun turns to sackcloth (goat hair)", "THEN the moon turns to blood"....after that, the Great Day of the Almighty will start. So, between now and the full solar eclipse on March 20th, 2015 (7 months), there should be a vast escalation in "signs".
For what it's worth, that solar eclipse? ALSO happens exactly at NOON in Jerusalem. Well, 11:58am actually.
Pay attention, that's not all, because there are 3 VERY important Jewish festivals for Isreal to God during this approach to the eclipse.
Rosh Hashana - Sept 25, the festival of Creation and Adam and Eve...the Beginning of all all things and the New Year for Isreal!! Second, is Yom Kippur on October 4th the Day of Atonement/Sacrifice to God by Isreal, their firstfruits. Third is Sukkoth, October 8th, the Day of Salvation, or Festival of Booths, to remind Isreal of the the booths they lived in when God saved them from Egypt. These are all within 2 weeks of each other and only 4 weeks away from today. Especially watch world events during this time, both in Isreal as well as world-wide up to the eclipse.
Here are 2 weblinks that are very succint and detailed. Well worth a look from anyone who's interested....critic or not. One is more scientific that the other....which correlates the most important Jewish festivals to God to these solar events.

For those interested....Gog in the Bible would be the geographical location of Western Russia...Magog, would be the countries west of Gog and throughout the mediteranean coastline.
Keep on the watch.
