The peak of the Orionid meteor shower (25 per hour) occurs at 17:00 UT. A new moon on the 23rd means that viewing conditions for this year's Orionids should be excellent. They should be viewable from c21st - 23rd October and will emanate from the 'club' of Orion near Betelgeuse.

The Lunar Straight Wall in Rupes Recta will be visible tonight.

OCTOBER 19 (Sun) – Mars gets a close shave as Comet C/2013/A1 Siding Spring makes a flyby at 18:28 UT. To see from the UK requires good viewing conditions and a view of the SW horizon. Siding Spring will be magnitude -6 from Mars but +10 from the UK. Source:http://danspace77.com/2014/08/22/comet-to-give-mars-a-close-shave-this-october/ which also provides excellent links.

OCTOBER 16 (Thu) – The brilliant Walther Sunset Ray will occur at 01:12 UT. Located in the ancient 145 kilometer (90 mile) Necterian age crater named Walther (Formerly Walter or Valtherus) is a special treat that occurs monthly for a matter of a few hours. On the western rim of the crater there’s a notch and when the Sun is setting low on the lunar horizon (When the crater is near the terminator) light penetrates the notch, creating a vast triangle or “V” shaped light ray across the craters floor that ends as it illuminates the central peak of the crater. (source http://danspace77.com/2014/10/01/space-junk-october-2014/) If you have a good view of the Eastern horizon then this is an opportunity to see it from the UK.

The Curtiss Cross, a shadowing effect along craters Gambart and Parry which create an “X” shaped formation and will occur at 0710 UTC. Jupiter is nearby the moon as well to give a nice double target in the same area of the sky.

10/25 Saturn is 1.0 degree south of the Moon, with an occultation taking place in central and western Europe, southern Greenland, and northeastern Canada, at 16:00 UT. NB: Take care and beware of the sun if attempting to view in the UK.

Neptune will be about 5 degrees below the Moon at 2100.

The Lunar X is on October 1st at 04:51 UT

The first quarter moon is at 1932 UT.

Uranus is 1 degree south of the Moon. If you are in Siberia, Greenland and parts of Canada the Moon will occult Uranus at around 0200 UTC.

The autumnal equinox occurs in the northern hemisphere at 2:29 UT

The Curtiss Cross, an X-shaped illumination effect located between the craters Parry and Gambart, is predicted to occur at 18:50 UT

The Lunar X appears at 15:59 UT.

The Walther Sunset Ray is visible at 13:39 UT. The brilliant Walther Sunset Ray is a special treat that occurs monthly for a matter of a few hours. On the western rim of the crater there is a notch and when the Sun is setting low on the lunar horizon light penetrates the notch, creating a vast triangle or “V” shaped light ray across the craters floor that ends as it illuminates the central peak of the crater.

The Maginus Sunrise Ray is visible at 10:32UT. As the Sun rises over the Crater Maginus (near the terminator) a beautiful sun ray shines through a break in the craters eastern wall. The result is a vast triangle or “V” formation of light cast upon the crater floor for a period of a few hours.

New Moon (lunation 1135) at 06:13 UT
