This lunar halo took place on February 22nd of this year.  Jupiter is visible about 11 degrees to the lower left of the Moon.

Here's the Belt of Venus, and the very beginning of the Twilight Wedge ... as seen from 32000 feet. I was sitting on the side of the plane opposite the sun and even at altitude the air was quite hazy that evening, so there was plenty of light getting scattered and reflected.

Also on the same flight (actually a little earlier than the photo above), there was a point in time where the sun, the plane, and the horizon must have been exactly aligned, because I was seeing shadows of clouds creating long lines, all converging at a single (presumably anit-solar) point on the hoziron.

2016-06-16 20.09.30_resize.jpg

 

There was also a span of time when we were flying through very thin, wispy cirrus clouds that were lit up bright orange and pink by the setting sun. I know how beautiful those kinds of sunsets are to look at from the ground, but it was nice to just appreciate the fact I was actually flying through a gorgeous sunset like that. Unfortunately the photos didn't really look like anything (cell camera couldn't find focus), so no pix to attach.

Dave and thomasr

 

Thanks for the beautiful pictures.

I wonder  how do you know to be out at the right moment  to witness such phenomena.... :flowerred:  

 

Yesterday I took pics of a rainbow.

It was rather faint and not full ,  only an arc.

But it allowed me to take my first rainbow pictures .

Here are two of my photos of double rainbows.  The first was taken from my front yard.  The second photograph was shot during last year's Cherry Springs Star Party.

Wow , very nice.

 

My compact  Coolpix S3300 was a rush Christmas gift but still I'm using it as it is.

Because it is my one and only camera... :mad:

With the rainbow , the light level was already low and my camera didn't handle well such situations.

I have to do manipulations to dig out details.

Like with  attached pics of a weak Moon halo of 23 Aprile 2016.

Here I present some pictures of  the so-called 'Belt of Venus'' phenomenon , or the   shadow of the Earth, produced by the rising sun and observed on the Western sky .
I took this pics  on February 11, 2015 with my  Allview A5 phone, while I was on my way home  on Brescia / Italy- Timisoara / Romania  route , with a  Wizz Air flight .
The peaks that appear in the photos belong to the Alps.
When taking the pictures, the plane flew toward  South-South East to avoid the South- Eastern spur of the Alps from Slovenia.
My place was on the right side of the plane and therefore I saw  through the porthole the anti-solar Western horizon, whith  ''the Belt of Venus'' phenomenon - especially visible in the first two pics.
I think the phenomenon of '' horizon  depression'' , which appears to observers who are at high altitude, helped to visualize so well   the Earth's shadow  in the first  two pics.

Today I discovered by chance these pictures in my small image archive  and I thought maybe you would like to see them.

I saw a twinned rainbow yesterday. I lasted a couple of minutes then it became a regular rainbow.

Thanks for posting the link with possible explanation of twinned rainbow.

The autthor is asking for more and detailed pictures of the rainbows.

 

Dave

 

Thank you for posting the link to Alan Dyer's site.

Amazing pictures !

 

On May 20 I took the folowing pictures of a Moon Corona.

It is very interesting to record the  evolution of such a  phenomenon which in the span of a  few minutes take so different appearances.

Nice pics, everyone!

 

I believe the color around the Moon is called an aureole.

Thank you Special Ed

 

Visualy I saw many times Moon Corona on just a quiet , hazy but  cloudless sky.

On such occasions ,not always only sometime , it was visible a sort of - let say-  circular  rainbow , a spectra with the red strip on the outside of corona.

It was a  real treat to gaze at it  with naked eyes and even better through binocular.

I have the Coolpix since two years but I had not an occasion to try record such a view.

Last night , right after the sunset , I took pictures of the would be Hunter Moon.

For a while , the Moon was accompanied by a Moon Corona and some contrails left by jets.

I used my Coolpix S3300 compact camera , mounted on the modified Velbon photo tripod.

The Moon was at 96% illumination , not Full , I emphasized this with the particle ''nearly''.

There were some very unusual and interesting cloud formations on Friday, October 7th, as the leading edge of Matthew approached south central Pennsylvania.  My wife captured what may have been part of a circumzenithal arc in some of the photos she took with her iPhone 6s.  I snapped the other photos shown here with my iPhone 4s.  They do not begin to convey what we actually saw.

 

Dave Mitsky

 

1) partial circumzenithal arc?

2) unusual clouds

3) contrail spreading out very rapidly

I did a bit of research today after seeing a couple of photographs of iridescent clouds taken by John Chumack and am now fairly certain that my wife captured an image of an iridescent cloud and not a portion of the circumzenithal arc.

On October 24 I was whitness to a very colorful sunset.

All lasted for about half an hour  but it was a time well spent.

The pics were taken with my Coolpix S3300 , the images are raw.

Some contrails added to the image.

We will try to figure out  how many degrees under the horizon should be the Sun to see such phenomenon.

Thank you for the thumbs up !

 

Here are two of my pics of the recent  Harvest Moon.

 

Harvest Moon 15.09.16.DSCN3244

 

There was some nebulosity around the Moon after Moon rising but did not developed into a proper halo or corona. 

 

Harvest Moon 15.09.16.DSCN3241

 

It was a beautiful view also with the naked eyes.
