Where do you see Friday's "Bloodmoon"?

Some places in Northern Ireland may be lucky enough to see a so-called Bloodmoon on Friday night.

The reddish moon, when it appears, will be the effect of a total lunar eclipse ̵

1; as the earth passes between the sun and the moon.

It will throw the moon in the shade for an hour and 43 minutes (19659007) How red that will be depends on the atmosphere at the time.

The "blood moon" effect is based on the visual effect that is produced when sunlight filters into the atmosphere and the colors orange and red are projected onto the moon.

In addition, during the solar eclipse, the Moon will be at the "Apogee" – the point farthest from Earth.

How does it work? Moon is turning red?

  • A lunar eclipse happens when the sun, earth, and moon are aligned so that the moon enters the Earth's shadow
  • In a total lunar eclipse, the alignment is perfect so that the planet blocks the sunlight of the moon
  • During a total eclipse, the moon may have a bright reddish-orange color known as the blood moon
  • The color appears to change when the moon is flooded with light that has passed through the Earth's atmosphere and then back to the moon moon tilts through refraction

The solar eclipse on Friday is the first visible since September 2015 from Ireland and will be the longest of this century.

"However, we will not see all of this darkness, as the moon will already be in the shadow as it rises from Ireland across the horizon," said a spokesman for the Irish Astronomical Association.

"The maximum of the eclipse is 21.21 BST, but the top of the moon will not rise from Belfast until 21:27 BST.

" The total number of sta The solar eclipse will end at 22.13 BST, and by then the moon will have risen to a height of only four degrees, or about eight times its own diameter, over the south-east horizon, "he added.

Lunar observers hope the clouds will stay away on Friday night

Analysis:

By Geoff Maskill, BBC News NI Weather

We had some beautiful nights watching stars this week. Unfortunately, Friday is not one of them.

For weeks we had high pressure and gave ourselves a very stable feeling for our weather. When it was strongest a few weeks ago, centering directly over Ireland, the sky was almost cloudless.

Now, for the first time in weeks, we see the high pressure finally erupting and feeding in a still more volatile Atlantic weather from the west.

A series of weather fronts, all driven northwest by a depression, are expected to bring clouds, wind, and rain to Northern Ireland by Friday night and weekend.

It means stargazers hoping to experience the lunar eclipse are likely to be disappointed.

The chances of a clear view are not good everywhere, although the odds of some clear slogans on the east coast of counties Antrim and Down are best, but I would not endure too much hope.

"You have to look as clearly as possible to the southeast, where the moon is deepest at the eclipse."

The Irish Astronomical Association holds two public viewing events for the Eclipse:

  • At the Knockagh War Memorial Monument on the hill above Greenisland, County Antrim
  • At the parking lot at Scrabo Hill, near Newtownards in the County Down [19659041] Are you hoping to catch a glimpse of the lunar eclipse or bloodmoon tonight? Submit Your Photos
