o

• The Jewel Handle or Golden Handle
  The Moon’s Golden Handle is visible from the UK once each lunar month, roughly 2-4 days after First Quarter Moon, when the Sun grazes the Montes Jura and lights their peaks while Sinus Iridum is still in darkness ~ this creates the bright “handle” effect along the terminator.
  o
• After the First Quarter Moon (half-moonlit), the Moon increases towards the Full Moon in the waxing gibbous phase ~ the time when the Jewelled handle shines brightest.
  o
• This effect is only visible for a few days each month ~ roughly 2-4 days after the first quarter Moon.
  o
• Equipment
  You will need a small telescope or binoculars (8×42 or 10×50) are enough to show the arc beautifully.

• Equipment
  While sometimes visible with high-power binoculars, a telescope is recommended to see the fine detail of the crater rims forming the Lunar X and V.
  o

• Look west to west-northwest about 30 – 60 minutes after sunset.
  o
• A clear, unobstructed horizon will help because the objects will sit fairly low.
  o
• Binoculars should give a beautiful view of the crescent Moon with the bright planets nearby.
  o

• The Moon reaches apogee ~ the farthest point in its orbit from Earth.
  o
• The Moon appears slightly smaller and dimmer in the sky compared to perigee.
  o
  o

• When Venus reaches perihelion, it means the planet has arrived at the point in its elliptical orbit where it is closest to the Sun.
  o

• Visible in the UK before sunrise.
  o
• Best viewing time:
  – Around 4am – 5am BST.
  – Direction: low in the eastern sky.
  – The Moon will be a very thin waning crescent.
  – Mars will appear as a small reddish-orange point nearby.
  o

• This month, look out for two bright planets ~ Jupiter and Venus in the western sky.
  o
• Keep watching the sky, as both will appear close together on Saturday 6th June, aligning in the same region of the sky.
