The Sun is our Star!

.......and as you would expect, our Star is hot, bright, dynamic, and sometimes quite violent.

At 93 million miles away, we are ideally placed at a point where the Sun provides just enough warmth and energy essential to our living planet, Earth.
At only 93 million miles, the Sun is close enough for us to view it's surface thru a relatively inexpensive scope from the comfort and relative safety (Sunscreen please) of our backyards on a clear and warm day.

What! Astronomy during the day? Lunt Solar wants to show you how.

Prominences:
These look like eruptions from the edge of the Solar disk. Prominences can be small spikey looking details, or large cloud-like detail with fine feather-like features.

They are, in fact, ionized Hydrogen-alpha emissions being projected from the linb.

Prominences are anchored to the Sun's surface in the Mesosphere, and extend outward into the Sun's Troposhere.
They typically measure many earth diameters.

Filaments:
These are strin-like features on the surface of the Sun.

At high resultion they take on a 3D effect due to the coller aspect of the suspended filament contrasted against the bright, hotter Sun.

They are actually prominences being viewed against the surface.

Spicules
A Spicule is a dynamic jet of gas about 500km long.
They move outward at about 20km/second thru the Chromosphere.

Father Angelo Secchi of the Vatican Observatory discovered them in 1877.

The Chromosphere is entirely composed of Spicules. These features can be seen as "fur"around the edge of the disk.


There's definately stuff to look at :)

Almir Germano from Brazil

Using my Lunt LS60, double stacked with the LS50 filter. Good seeing and transparency (4/5 and 3/5).

Lumenera SkyNyx 2.2, previously owned by Andy Lunt (it is a small world)

Two.avi, one for the proms and one for the disc. Hard to focus on the screen in full bright daylight, very hot under the hood!

I inverted the orientation of the image for the northerners.

The small blue dot is for comparison with Earth. Very humbling vision.

The AR visible were very active indeed, nine flares in the subsequent week!

Down bellow goes another image.  Above is of myself with a big smile beside my Lunt….

And my place! I do all my observations from my backyard.

Living in a 400.000 people town, dark skies are a thing of the past. During the day we have the skies frequently obscured by ashes from the nearby sugar cane plantations (yes, they still burn before harvesting). Otherwise things are good… =]

Clear skies!


This one is an animation, from jan 12th, 13:49 – 14:12 UTC. This “caterpillar” prominence and the loops are from AR 1402 and 1401, just before they began to show up in the earthside of the Sun.


Same day, a little earlier. Full disc animation. You can see a “microflare” going off in AR 1395. Cool, isn’t it?

This sunspot cycle is becoming a thing to remember (not to mention a little spooky…).  Here goes another one, from the current “actress”, AR 1320. Wow… naked eye sunspots, humongous.  This one is in white light, using my Celestron C8, Lumenera, Powermate 2,5. No H-alfa that day, Sol just went behind  my neighbor wall…
