Eclipses of August 2008

Partial Lunar eclipse on the evening of the 16th August.

Fifteen days after the Solar eclipse when the Moon was full again there was be a Partial lunar eclipse. This occurs because at this time the angle of the Moon's orbit intersects the ecliptic at Full and New Moon. This was a fairly deep partial eclipse with over 80% of the Moons surface in the umbral (total) shadow. It rose just as the Sun set at about 9pm and the deepest eclipsing occurred at 22:10 when the moon was just a little less than 10 degrees above the east south eastern (128deg) horizon.

From where I was in West Cork the Moon was visible for most of the eclipse with only the odd cloud interrupting the view, Picture is not the best as I had only a zoom lens and no tripod.

Solar eclipse of August 1st

On the first of August there was a total solar eclipse visible along a narrow track that started in eastern Canada, crossed Greenland, then the Arctic seas before making landfall in Northern Russia and ending in mainland China. Form here in Southwestern Ireland we saw a partial solar eclipse with less than 25% of the sun's diameter covered by the Moon.

First item as always is safety. NEVER look at the Sun directly, even with just your eyes. Use special eclipse glasses or proper solar filters. You can also use an ELECTRIC ARC welding mask if the filter number is 13 or higher. A safe way of seeing the event is to project an image of the sun onto a white card with one side of a pair of binoculars. If in doubt don't risk it! There will be more eclipses but you only have one pair of eyes.

The first signs of the moon in front of the Sun (first contact) was visible, on schedule at about 9:25 BST under pleasantly clear skies. The Moon's bite got bigger and bigger until its maximum cover for our location at about 10:09 am. as shown above. The event was over at 10:52 when the Sun regained its more usual round appearance.

Total Lunar eclipse of Feb. 21st '08 seen in Kerry.

Being the last total lunar eclipse to be visible from Ireland from start to finish a special effort was put in to see it. The weather did its best to spoil the show but thanks to a local weather effect here in Tralee where, given a strong wind over the mountains, we often get clearances in the lee of the hills. So with a bit of driving we were some of the few in Ireland to see the event more or less in its totality.

The partial phase always looks odd with "bite" missing out of one edge. However it is nothing compared with the eerie appearance of the totally eclipsed Moon with the stars (and Saturn) hanging beside it in the sky.

What was a bright moonlit night just half an hour previously turns into a surreal darkness with a ruddy red Moon hanging among previously unseen stars.

Totality numerically lasted for 51 minutes but the lower limb of the Moon never really darkened as it was always close to the edge of the umbral shadow.

The image over was taken at mid eclipse at 03:26 and is considerably brighter than what was visible to your eye.
