The colours in this sunset were just magnificent, it’s not very often you get to see such vibrate and vivid colours like this in the sky, and it was just stunning!
 
I quickly ran a grabbed my little Canon G15 point and shot camera and took some images, there’s no processing here, this is the real colour of the afternoon sky…just magnificent :-)
Exposure settings were aperture f2.8, ISO320 and time was 5.02pm.
 
What courses all these stunning colours?
 
At sunset the Suns light has a lot more of the Earths thick atmosphere to pass through as it sets low on the western horizon and depending on how much dust particles or other aerosols are in the sky this determines how colourful the sunset will become.
 
On the electromagnetic spectrum red has the longest wavelength of any visible light, this is why sunsets are often a beautiful golden yellow or red colour on the horizon, the extremely long path of sunlight as it travels or scatters through the atmosphere blocks all the other colours.
 
Below you will find a few websites that explain the science behind a beautiful sunset…but really they are just so beautiful so just enjoy them :-)

Please go to the live broadcast that both NASA and the European Southern Observatory (ESO) will be broadcasting from 5.30am on the 3rd July (Australian EST).
 
NASA has partnered with the Exploratorium in San Francisco to bring live views to people across the world of a total solar eclipse, occurring Tuesday, July 2, over South America.
 
The eclipse will only be visible directly to observers within the path of totality, which stretches across parts of Chile and Argentina.

With the upcoming Total Eclipse of the Sun due in two days times in Chile I’ve turned my mind to our wonderful solar eclipse we had here in Queensland, Australia on the 14th November 2012.
 
We were at a place called Ellis Beach just north of Cairns in tropical Queensland and at that time of year its notorious for heavy rain, and so it was as day dawned that the eastern sky was leaden with clouds, but then a miracle happen and from our beach location we saw the incredible eclipse of the Sun.
 
I wish everyone who has ventured to Chile and other places under the shadow best of luck for the 2nd July, seeing this spectacle is one of the most amazing things you will ever experience in your life :-)

Today marks the winter Solstice here in the Southern Hemisphere, so while most of you who live in the Northern Hemisphere are experiencing the longest day of the year, we here in the land down under are experiencing the shortest day of our year…. isn’t living on our Earth just amazing!
 
The Sun is indeed very quite and absolutely blank so no fireworks to celebrate this special event from the Sun :-)
 
Image taken with a Canon 70D camera and Tamron 18-400mm lens and 2x teleconverter making a focal length of 1280mm. I used a glass solar filter attached to the lens to safely image the sun. Eight images were stacked in RegiStax6, exposure time was 1/500th second and ISO200.

We had such a beautiful clear day here today, so I raced home and spent most of the day imaging our Sun with my different cameras and telescopes to capture these two big sunspots.
 
Active region AR2740 has now split up which can be seen quite clearly and the new sunspot AR2741 has a very dark umbra and a large penumbra area surrounding it.
It looks like this one is going to be quite an active sunspot too!
 
These images were taken with my 127mm refractor telescope with a glass solar filter attached using a Canon 700D camera. The first image was taken with a ZWO ASI 120MC-S camera with a 2x Barlow lens.

Late yesterday afternoon at 4pm (AEST) I got the biggest thrill when I put my little 60mm Lunt solar telescope onto my mount and pointed it at the Sun and saw AR2740 going off like a rocket!!! These four images were taken over just 10 minutes in duration and it was very exciting to watch and capture.
 
If you look closely at the active region (middle of image) you’ll see the solar material being blasted away and travelling across the surface of the Sun as a dark mass of plasma…a small CME in motion!
 
I was very lucky to capture this event as the Sun was getting very low and I’d just packed away my refractor telescope, I just thought I would take a peek at the Sun in H-alpha to see if it was doing anything exciting…and Wow, it was!
 
Images taken with a Lunt 60mm solar scope and a ZWO ASI 120MC-S camera at prime focus, I captured AVI movie files and stacked them in RegiStax6 and processed in PS CS4…there was also a small prominence on the eastern limb so maybe there is another sunspot coming….
 
Note from Noeleen:
If you watch the slideshow you will see the path of the solar material being blasted away from the Sun
​over just a few minutes...Wow!

The next day an image of this solar flare from the Solar Dynamics Observatory was posted on Spaceweather.com

After so long with no activity on the surface of the Sun we now have a huge active sunspot designated AR2740 which is the twice the size of Earth.  I set up both my telescopes this afternoon and finally the clouds cleared long enough to take some images. I had to be quick because clouds were rolling across the sky!
 
For the full disc of the Sun I used a Meade 80mm refractor telescope with a solar filter attached and a Canon 700D camera with a 2x Barlow lens, the exposure time was 1/320th second and ISO 200. For the high magnification image I used a ZWO ASI 120MC-S camera with a 2x Barlow lens, 2000 frame AVI file stacked in RegiStax6.

Information from Spaceweather.com on the 6th May 2019
 
ACTIVE SUNSPOT: Big sunspot AR2740 is turning toward Earth and crackling with solar flares. The most intense so far registered M1 on the Richter Scale of Solar Flares.
NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash on May 6th.

​Sunspot AR2733 is now degrading after it unleashed a C5 class solar flare on the 26th January, it’s now heading toward the western limb of the Sun. Perhaps we may see a lovely prominence on the solar edge as it rotates out of view…now that would be nice to see if the weather is fine :-)
 
Images taken with a 127mm refractor telescope and a Canon 700D camera with a 2X Barlow lens attached, 5 images stacked in RegiStak6 and processed in PS CS4. Exposures were 1/250th second and ISO200.

(Right) I used my 127mm refractor with an Orion glass solar filter attached for safe viewing and taking pictures of the solar surface.
 
(DANGER…NEVER look at the Sun without proper solar filters on your camera lenses and telescopes)
 
Please see below a small movie of the explosion from AR2733 taken on the 26th January from
NASA’s SDO observatory.

​I had another peek at the Sun late yesterday afternoon and Yep…it’s spotless again! 
​
When I turned around and looked up to the east I spotted a lovely gibbous Moon in a clear blue sky,
​which looked very pretty :-)
 
Both images were taken with a Canon 70D camera and a Tamron 18-400mm lens with a 2x telecoverter making a focal length of 1280mm.

A glass solar filter was attached to the lens for safe viewing and imaging of the Sun.

Yay! There’s a new sunspot on the Sun today for the New Year and it’s been designated AR2732, it’s quite small and faint but it may turn into something exciting for us solar observers :-)
 
Images taken with a Canon 70D camera and a Tamron 18-400mm with a 2x teleconverter, a glass solar filter was attached to the lens for safe viewing and imaging of the solar surface. 10 images were stacked in RegiStak6 and lightly processed in PS CS4…Happy New Year to everyone!

Christmas Day Sun Today :-)
Our beautiful Sun today on Christmas Day after weeks and weeks of rain and thunderstorms…Merry Christmas to all and happy holidays!
 
I just had to add a Santa hat to our very bland Sun for fun :-)
 
Image taken with a Canon 70D camera and a Tamron 18-400mm lens with a 2x teleconverter attached, a glass solar filter was fitted to the lens for safe viewing and imaging. Exposure time was 1/500th second and ISO200.

~ Current information on the Sun ~
 
The Sun is now experiencing a period of solar minimum with over 200 days this year without sunspots on its surface, gone are the days when so much activity could be see on the surface of the Sun…I really miss all the excitement!
 
The image (left and above) of the Sun that I took on Christmas Day is completely bland and spotless!
​
To safely take images of the solar surface you must always use a solar filter on the lens of your camera or telescope. I haven’t even used my Lunt 60mm (Ha) solar telescope much this year as the Sun has been very quite in this H-alpha wavelength as well.
 
But there has been another type of activity on the Sun that’s quite intriguing, and that is these corona holes that open up and expel subatomic solar particles throughout the solar system. They are not as powerful as a CME but they still produce some awesome aurora when they hit our atmosphere.
 
When these solar particles hit the oxygen and nitrogen in our Earths atmosphere they excite the gases and release a photon of light that produces the coloured curtains of light of the auroras.
 
It was one of these incredible episodes that produced the stunning northern lights  (Aurora Borealis) that my husband and I witnessed in March 2018 when we were on board the Hutigruten ship called the Nordkapp that cruised up and down the Norwegian coastline. Wow…what a magical experience that was!!!!
