Sun Not in Pisces


  According to the pseudoscience of astrology the Sun enters the constellation of Pisces the Fishes on Sunday February 18th. In fact the actual position of the Sun is still within the boundary of the constellation of Aquarius the Water Bearer, as this graphic shows. The Sun had just entered Aquarius 2 days ago.

   Read a little more about how astrology has the Sun incorrectly placed in a previous blog, and in another blog discussing the effects of precession.

Sun Enters Aquarius-2018

feb-view from earth   Friday February 16th the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Capricornus the Sea Goat and into the constellation of Aquarius the Water Bearer. This is the true or actual position of the Sun as opposed to the pseudoscience of astrology which usually has the astrological Sun one constellation ahead or east from the Astronomical Sun’s position, which will be Sunday February 18th when the sun is not in Pisces according to astrology.

February Moon at Descending Node


   Wednesday February 14th the thin waning crescent Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
    
   
     

   On the day of the node crossing the 28-day old waning crescent Moon will be over the eastern horizon about an hour before the Sun rises. The Moon will reach new phase approximately 24 hours after this node crossing.

Lunar Eclipse – January 31 2018

Here are two pictures from the rising Moon last evening.

   
   And this morning got a late start out the door – made a mistake and let the dogs out in front (north side) while I looked to see where the Moon was. Then chased the ‘guys’ for a while until they peed and sniffed enough and got them back inside.
Drove out east to our community park for a better horizon. Had planned on using 3 cameras but then applied the KISS or Occam’s Razor logic and set up one camera. In reality I had about 30 minutes prior to totality and only a couple of minutes as you see in the video near totality. The clouds were too thick near the horizon.
   This is a sequence taken at 300mm with several exposure times, f-stop and ISO changes along the way.

Moon – Regulus Conjunction


   Thursday morning February 1st the waning gibbous Moon will be in conjunction with the star Regulus in Leo the Lion. Depending on your location the two will be anywhere from around 1o to at least 5.5o as is the separation from my location.


   And while outside remember to turn toward the south and east to see Jupiter, Mars, and Saturn stretched out above the horizon. The brighter stars, Spica in Virgo the Harvest Maiden and Antares in Scorpius the Scorpion are also arranged along the same ‘line’ as the three planets.

A Lunar ‘4-fer’ Plus Planets: Perigee; Ascending Node; Blue Moon; and a Total Lunar Eclipse!!

   Our Moon reaches full phase for the second time this month on Wednesday January 31st at 13:27 UT (7:27 am CST). According to the popular definition for a ‘Blue Moon’ the second full Moon in a month is known as the ‘Blue Moon’. This happens about every 2.5 years with this year being a little more different in that there will be a second Blue Moon month in March.

   Our Moon reaches perigee, (closest distance from Earth), for this orbit on Wednesday January 30st at 9:48 UT (3:38 am CST). At that time the Moon will be at a distance of 28.14 Earth diameters (358,994 km or 221,204 miles) from the Earth.

      On Wednesday January 31st the full Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.
      
   What do you get when you have the full Moon at a node crossing? An eclipse – in this case a total lunar eclipse. Timing for this eclipse favors viewing from the western half of the continental United States. Here is a link to download a lunar eclipse page information page (PDF) from the NASA eclipse web site
   Mid-eclipse has the darkened Moon a few degrees away from the open star cluster, M-44, commonly known as the Beehive Cluster. Both the Moon and tM-44 will fit within the field of view of binoculars.
   Here is a summary of the eclipse event starting times from the NASA Eclipse web site. My local time, CST, is UT-6 hours. An important time will be local sunrise-moonset time. For me local sunrise and Moon set time is 7:26 am CST meaning that totality will be in progress as the Moon sets. Here is a link to the Sun and Moon Data calculator web page at the U.S.N. Observatory so you may determine your local sunrise/moon set time. Here is a link to the Hermit Eclipse web site for more information about the eclipse and an interactive map showing eclipse event particulars.
P1 = 10:51 UT 4:51 CST
U1 = 11:48 UT 11:48 CST
U2 = 12:51:47 UT 6:51 CST
U3 = 14:07:51 UT 8:07 CST
U4 = 15:11:11 UT 9:11 CST
P4 = 16:08:27 UT 10:08 CST

   As the eclipsed Moon is setting in the west turn toward the south and east to see Jupiter, Mars, and Saturn plus the bright stars Spica and Antares.

Sun Enters Capricorn – Not Aquarius

ww
   Friday January 19th at 20 UT the Sun in its apparent eastward motion along the ecliptic enters the boundaries of the constellation Capricorn the Sea Goat. This is the actual location of the Sun.
   Interestingly, according to the pseudoscience of astrology, 7 hours later, at 3 UT Saturday January 21st, the Sun should be entering the constellation of Aquarius the Water Bearer.
