What’s A Sun Halo?

What’s A Sun Halo?

Ever seen a ghostly rainbow halo around the Sun?

A Sun halo is caused by the refraction, reflection, and dispersion of light through ice particles suspended within thin, wispy, high altitude cirrus or cirrostratus clouds. As light passes through these hexagon-shaped ice crystals, it is bent at a 22° angle, creating a circular halo around the Sun. The prism effect of light passing through these six-sided ice crystals also separates the light into its various color frequencies, making the halo look like a very pale rainbow, with red on the inside and blue on the outside.

Folklore tells us Sun halos can predict the weather:

A ring around the Sun or Moon
means rain or snow is coming soon.


Occasionally, brighter areas will form along these halos, creating a mock Sun, or “sundog.” Sundogs are known as parhelia (or the singular parhelion) to astronomers, from the Greek words meaning “beside the Sun.”

    Hi….. I simply guess this thing around the Sun meant that lot of rain is coming to wash away this dreadful disease, I’ve seen it on the 22 of march 2020

  • Lorie says:

    We are seeing one right now! It’s beautiful.

  • Anita Beiro says:

    I saw one a few years ago in New Jersey. Then again a few days ago I’m Aruba while I’m vacation. They are beautiful to see,

  • Kedre says:

    I just witnessed my first sun halo today here in NE Oklahoma. It actually was partially a double halo. It lasted for at least 30 minutes. I wish I would’ve had a camera to take a picture. It was amazing as I stood in awe! Thank you Lord for giving us beautiful blessings. It sure made me smile and made my day. 🌈

    Had a large halo around the sun at noon on January 31st in Cuiaba, Mato Grosso, Brazil (central western)

    Hi I live in timboon victoria Australia, have got a sun halo today

  • Robert says:

    Rainbow sun halo persists 1-5-20. Concluded specially engineered aerosols dispersed into atmosphere are responsible. Samples of aerosol filament fallout have the same spectra as sun halo. Sun dogs, which were previously quite rare are now common, ostensibly due to aerosol dispersal, the alleged purpose of which…admitted to by authorities only when backed into a corner…is to retard global warming. If you say so, Mister Man! Never mind increasingly bitter winters in the higher latitudes, consistent with well documented grand solar minimums, the most recent of which commenced in 2012 (See “Prophecy of the Eagle and the Condor”). Mum’s the word on that one. Credible researchers claim these aerosols interact with electromagnetic radiation generated by very sophisticated ionospheric heater arrays (HAARP) having the capability of a wide range of fantastic phenomena. Jules Vern on hallucinogens could not make this stuff up. If you find domestic politics bizarre, it pales by comparison to the disarray among climatologists. Reminds me of a fireworks item dubbed, “Sky Monkies Violate the Heavens”. It’s not nice to monkey with Mother Nature.

    I just took a photo of a sun halo by blocking just the sun enough to show the colors. January 5, 2020. Georgetown, Texas. Awesome!

  • Robert says:

    Mayan Calendar marking 2012 as ‘end of the world’ scenario was an intelligence operation deliberately contrived to obfuscate the end of one age and the commencement of another. Just as the cosmic clock struck 2012, the sun responded by receding into a quiescent state known as a grand solar minimum presaging another ice age. The collective consciousness of humanity has not yet risen to the occasion due to deception by those who in whom we have mistakenly placed our trust. We are living in the most interesting of all times. Strap on your seat belts…we are in for one hell of a cosmic merry-go-round. Fear not…consciousness is rising. All is consciousness…unquantifiable, all-pervasive infinitude.

    Sunset in Wimberley, Texas Jan. 4, 2020….concentric rainbow halo around sun. Sun gazing with optical oscillator reveals sun streaming forth extra-dimensional archetypical geometrical codex. The sun is a cold ferrite planet with continents surrounded by liquid hydrogen oceans. Sun’s photosphere is a relatively thin (3000 miles thick) sheath of plasma akin to our planet’s ionosphere, only far more energetic. Stars are both the hottest and coldest objects in the universe. They are by definition giant superconductors manifesting all the characteristics thereof. 1561 Celestial event over Nuremberg, Germany possibly a glitch in the holographic projection we call reality. Description of manifestations during that event are very similar to those observed through optical solar oscillator, especially concerning the ferrite appearance of the sun’s dark planetary surface. Both Albert Einstein and Max Planck confirmed the a-ethereal nature of reality. Einstein said, reality is an illusion, although a very persistent one. Just a few words with mind-boggling implications missed by many. Culmination of particle research (CERN/LHC) disingenuously claimed discovery of Boson, aka, “God Particle”. What they discovered but did not report was that matter is condensed energy that is being projected into existence from an unquantifiable background source. Many of the formerly aesthetic scientist got religion all of a sudden but were sworn to silence. CERN/LHC is not a research facility. It is an interface capable of manipulating the hologram we call reality. Welcome to…the MATRIX!

  • Josephine says:

    Saw one at around eleven a.m. lasted for a long time

  • Sara M. Simonetti says:

    My brother saw one today in NY, first time ever. I’ve seen them around the moon but never around the Sun.

  • Donna says:

    I grew up back in Connecticut and saw them all of the time back there. I lived in both Colorado and Arizona and see them several times a year. I will ask anyone if they know what they are and I have never met anyone who knew what they are . I have always gotten the same response- No they have no idea what they are. I am always looking up in the sky to find my next one. There was one in the sky late this afternoon today!

  • Evelyn reddy says:

    Just saw a sun dog in Lakeland FL tonight! 11/22/19

    The first one I ever saw and was told what they were, was on a chilly Yacht Sail around Lake Tahoe in May… We see them occasionally here in Arizona.

  • Kirby Sirois says:

    I saw one of these driving home from work the other night and could not figure out what I was seeing…now I know! It was so awesome!

  • Russ says:

    What does it mean if only a partial on north or south

  • TheMaineMan says:

    That’s really cool, but Jaime is right NEVER look right at the sun without some serious eye protection.

  • Brenda says:

    Yes, recently on two different occasions! The thing is I, nor anyone else i have talked to, Remembers having seen one before. Are these rare occurrences in Texas Gulf Coast area?

    • Jaime McLeod says:

      Hi Brenda,
      Sun halos are relatively common in all regions, though they do tend to happen more often on cool, crisp days (and, consequently, more often in colder regions). Because it is not advised (and can be painful) to look directly at the Sun, though, it can be hard to spot one, especially if you aren’t wearing sunglasses. In fact, I had to put on Sandi’s sunglasses to see this one. Looking without them was too blinding.

  • Carybear says:

    I have because I live in Nova Scotia. it’s not rare to see a sundog in January.

  • If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
