Equinox, Solstice, Perihelion and Aphelion tables for years 2000 to 2020

Equinoxes, Solstices, Perihelion, and Aphelion, 2000-2011

Obliquity , the tilt of the Earth's axis reaches a maximum each six months, and returns.

That creates the seasons, as the Earth revolves around the Sun once each year.

If the Earth's axis had no tilt, there would be no seasons at all.

The obliquity can vary by a few degrees, so an Earth angle of 23.4° sits near the middle of the range. It varies over 41,000 years.

Hi Claudiafox, Thought I'd share a link to the dates and times for lunar perigee and apogee for 2004-2020: http://www.saao.ac.za/public-info/sun-moon-stars/m...

Thanks for that RetroJoe. I see key dates, I will do a new hub now with thoughts on these dates.

Dec 12 23:15

Dec 25 21:21

Yeah, that Dec 12 date perigee, along with a new moon 9.5 hours after, caused some flooding in Huntington Beach, California (and I am sure other places as well). Here's another link, this one gives the phases of the moon followed by a calendar of astronomical events for 2013 (links to future years at bottom of the same page): http://astropixels.com/ephemeris/astrocal/astrocal... Also, I agree that things do look like they are about to pick up speed in destructive earthquakes during the next 2 months (more on that in an upcoming hub of mine)..

Thanks for that. Six M6+ quakes and two of M7+ for December 2012 so far. More to come, I think. I see astrology charts show earthquake trines; so lets see how that lines up with the space indicators. I think earthquake risk very high for the next two weeks.

Looks like the month has been average so far for quakes in the magnitude 6.0-6.9 range, but just one 7.0-7.9 quake is the monthly average and already we have two. Not sure where you heard that trine aspects in astrology can signal times of destructive earthquakes, but that runs contrary to what I have found in my research. I just searched for other opinions and found the following that matches what I have found (at least in terms of the harmonious aspects such as the trine): "Thus, while oppositions, quincunxes, squares, and sometimes conjunctions between certain planets seem to correlate well with the occurrence of earthquakes, trines, sextiles and conjunctions between specific planets seem to correlate with periods during which earthquakes are least likely to occur." Apparently conjunctions are neutral in this regard, but for trines and sextiles, they would tend to neutralize (or at least decrease) the possibility of an ensuing earthquake.

HI RetroJoe. Thanks for your comment. You have the astrology expertise; I'm in the Space Weather Department! I don't understand "trine". I mean the "archers bow" formation for 22 December 2012, for example which can precede large earthquakes. But on the space weather front alone, the data would suggest some mid-range events in the next few days; +M6 and maybe +M7. Unusually, this month - lines of smaller quakes aligned on polar latitudes, both North and South.

Ah, I see that there was just another 6.0 magnitude quake in Indonesia.. Want to bring up a couple of points here. In a recent hub I designated that an 11.5 day period starting at 0000UT on 12/12 would be a window for earthquakes of at least 6.5 magnitude (based on astrology). I've been tweaking my prediction methods lately and now feel that the window should start a bit later and end much earlier (now feel it should have started at 0800UT on 12/13 and end at 0500UT on 12/17). There is one small exception near the end of the old window though. That exception begins on 12/22 at 1825UT and lasts just 4 hours. In addition, I now feel that there is a similar window that opens two days later on 12/24 at 1900UT and lasts 6 hours.

Yes, looking at it from the space weather data I expect a series to come in the mid-range - sequence today and next few days; trending westwards probably Guatemala, (Indonesia region - as you noted in Sulawasi) - and then risks of Myanmar, Maybe South China, India peninsula or ocean, and perhaps African Rift Valley. A pattern seems to repeat daily at the moment, and starts with Sunrise in Guatemala.. look forward to your hub publication.

Yes, coming from the Space weather data angle I see events ahead also. The Sulawasi M5.1 you mention is in Malaccas, north of Indonesia mainland and in the west ward moving earthquake risk-band I expected. One also in that zone just now - Marrianas.
