Solar photosphere definition

 

" Kurt loves searching for and purchasing 'preloved or secondhand' astro equipment for the Jodrell Plank Observatory. The above is a Herschel Wedge. This can be used with telescopes having an aperture equal or less than 80mm in diameter. The wedge has an integral blocking filter, vents most of the remaining heat etc. via the prism and out of the wedge through a heat sink.  The Herschel Wedge delivers 'high definition' images of the Solar Photosphere in white light. We hope to use this new piece of kit to provide high definition images of sunspots at high magnification." - Joel Cairo CEO of the JPO still the UK's most easterly Astronomical Observatory.

"Kurt is sitting in the 'Visitor Centre' after having been discharged from the hospital. With nothing much to do, he asked Google Gemini AI to create a time-lapse video clip of the gravitational interplay between the two spiral galaxies over 25 million years, using the above image and Astrophysics.

Now, here at the JPO, we all take AI with a big 'pinch of salt' and the following video may be more 'scraped' than 'calculated' but we all thought it was worth posting for general interest." - Joel Cairo CEO of the Jodrell Plank Observatory.

Deep Time and the Cosmos

 

"As Einstein would have said, there is no preferred frame of reference. Everything in the cosmos is moving and separated by vast distances. Mostly from our frame of reference, both in time and space, stars and the like seem unchanging. This is only an illusion created by the brevity of human life compared with the life of stars and the enormous size of the Cosmos. 

Kurt, some time ago had captured an image of the Plough asterism in the constellation Ursa Major the Great Bear and I decided to ask Google Gemini AI to create a stop motion video clip showing how his image of the Plough would change over 10 million years in 500,000 year increments. The AI was tasked with taking into account relative movement and the life and death of stars. I was rather impressed by the result which I assume is realistic as well as beautiful" - Joel Cairo CEO the Jodrell Plank Observatory.

Kurt Thrust is unwell.

" The trouble with having a very old astronomer, like Kurt Thrust as the Observatory Director, is that sooner or later they become a bit unwell and unable to do their job. Quite honestly, the JPO Team has been covering for him for some time and we all have been keeping him going with a steady stream of tea, sympathy and incontinence pads. Anyway and quite unexpectedly, Kurt was admitted to hospital for tests but we hope to see his return to the Observatory in the next few days. In the meantime, he has insisted that posts should continue and that the blog should not go 'Dark'. What an astronomical trooper!🔭🤣" Joel Cairo CEO of the JPO the UK's most easterly Astronomical Observatory

" The above images showing the  current view of the solar photosphere were obtained and derived from the SOHO satellite. I was rather annoyed, that I wasn't back at the Jodrell Plank Observatory and able to image sunspot group 4465 using the 127mm apo refractor, a Baader white light filter and our latest fast video camera. I'm down but not out! " Kurt Thrust still the current Director of the Jodrell Plank Observatory.

The Flaming Star in the constellation Auriga - NGC 405

" The one thing we have in depth at the Jodrell Plank Observatory is data! Loads of the stuff held; on drives, memory sticks and discs from times gone by! So when the nights become short in summer or when the weather takes a turn for the worse, our team at the JPO resort to the existing data for 'shots and giggles'.

This afternoon our specialist imaging engineer, Pip Stakkert, used a variety of software to process data captured with our Seestar S30. 

NGC 405, the Flame Nebula, in the constellation Auriga, is an interesting nebula in that it exhibits both emission and reflection nebulosity. This however, makes processing tricky. Pip decided to use the SHO (Sulphur, Hydrogen and Oxygen) colour palette and this very much enabled the blue emission nebula to be 'showcased' against the very bright Hydrogen Alpha nebulosity, which in standard RGB format overwhelms it". - Joel Cairo CEO of the Jodrell Plank Observatory.

NGC 405 The Flaming Star Nebula

"The Flaming Star Nebula, designated IC 405, is a complex emission and reflection nebula located approximately 1,500 light-years from Earth in the constellation Auriga. It is one of the most striking examples of a nebular region in which both ionized gas and interstellar dust contribute significantly to the observed appearance.

At the heart of the nebula lies the hot, blue O-type star AE Aurigae, whose intense ultraviolet radiation interacts with the surrounding interstellar medium. The red portions of IC 405 are produced by emission nebula processes: ultraviolet photons from AE Aurigae ionize hydrogen atoms within the gas cloud, and when the electrons recombine with the hydrogen nuclei, they emit characteristic red hydrogen-alpha radiation. Interwoven with these glowing regions are blue filaments and wisps formed by reflection nebula processes, where microscopic dust grains scatter and reflect the blue light of the star. This combination of red emission and blue reflection gives the nebula its distinctive colour contrast.

The nebula's dramatic “flaming” appearance arises from complex filamentary structures of gas and dust that seem to stream away from AE Aurigae in long-exposure images. Current evidence suggests that AE Aurigae is a runaway star, moving at high velocity through the interstellar medium after being ejected from the region of the Orion Nebula several million years ago. As the star travels through the cloud, its radiation and stellar wind compress, heat, and illuminate the surrounding material, helping to shape the nebula's intricate morphology.

Infrared and ultraviolet observations have revealed that IC 405 contains not only ionized hydrogen but also molecular hydrogen, warm dust, and complex carbon-bearing molecules. The interaction between AE Aurigae and the nebular material produces shock fronts and regions of enhanced heating, making IC 405 an important laboratory for studying the physics of star–cloud interactions, dust scattering, molecular excitation, and the evolution of the interstellar medium".

Scientifically, the Flaming Star Nebula is therefore not merely a visually beautiful object; it is a dynamic astrophysical environment in which radiation, gas dynamics, dust physics, and stellar motion combine to create a remarkable example of an emission–reflection nebular complex". - Professor G.P.T Chat visiting astrophysicist at the Jodrell Plank Observatory.

The Sun and the Sky at Night - A Perfect Storm

 

Jolene's completed White and Red light Safety Solar Filter
used with the JPO's Seestar S30
to capture recent images of the Solar Photosphere.
 

" Our sponsor George Roberts was so pleased with Kurt's recent solar images using Jolene's bespoke filter that he uploaded one of the photographs to his and the BBC 'Sky at Night' Flickr accounts.

George received an email advising him that one of our solar images would be shown on The Sky at Night program to be broadcast on the 08 June BBC Four and subsequently made available on BBC iPlayer  -  'Space Weather: The Perfect Storm'.

I have included a short and relevant video clip taken from iPlayer but would recommend those interested in 'space weather', to view the whole program, which is both informative and interesting." -Joel Cairo CEO of the Jodrell Plank Observatory.
