"Devils Tower Milky Way and Aurora"

Shooting the Milky Way in the early hours of 5/7/2013, It was a spectacular night for stargazing. Upon editing I realized I caught some very faint red Aurora on the horizon and also a satellite that grazes the top of Devils Tower.

High Quality:

Devils Tower Milky Way and Aurora by Brennan Jontz Photography, on Flickr

Captured this image just this morning (5-13-13) in the north western part of South Dakota. I am very new to photographing the Milky Way and much to my surprise, I was able to capture quite a bit of detail from the Milky Way in the reflection of the lake.

Solar prominence in CaK light (Calcium II K)

Light from singly-ionized calcium ions in the Sun's upper photosphere and chromosphere (up to 2000 km altitude). Because the blue Calcium K Line (393.3 nm) is sensitive to magnetic fields, magnetically active structures show up in high contrast against the surrounding chromosphere. Places where moderate magnetic fields exist show up bright whereas images of high magnetic fields are dark.

In this CaK image, you typically see brightness along the edges of large convection cells called supergranules and in areas called plages. Dark sunspots are also visible.

Spots on the sun are areas of high magnetic field which appear dark to their surroundings (5,800K) due to their cooler temperature of around 3000-3500K. Spots consist of a dark central region (umbra) and are surrounded by an annular region of dark and bright filaments called the penumbra. Within a developing active region (sunspot
group) tiny spots form initially without a developed penumbra and are called pores. These are usually relatively short lived or can develop a penumbra and become a fully developed spot.

The chromosphere is a place of high solar activity. In the course of a few minutes we can observe changes in the ejecta and prominences, in the path of the filaments, and as matter flows following very characteristic arches. Chromosphere is also visible in the light emitted by the ionized calcium, in the violet part of the solar spectrum in a wavelength of 393.4 nm. This light comes from calcium atoms that have lost an electron.

Dodging lots of big, white, fluffy clouds around midday on 05-13-2013, I spotted this rather large solar prominence. There was barely enough time between cloud shadows to grab a 1,000 frame AVI using an IS DBK41AU02.AS imager. This was stacked via Registax 6 then processed in Photoshop to produce the final image as shown here.

The image of the Earth is superimposed to scale in order to illustrate the amazing order of magnitude of this solar event!

Noctilucent Cloud by mharveyww1, on Flickr

I sincerely hope I'm doing this right. I've been a fan and follower of APOD for years but have never joined this group or tried to post an image.
The more I read the instructions for image posting, the more I felt like a Neanderthal trying to lear calculus.

If I'm doing this all wrong...please be kind and HELP ME!

Thank you so much,

Mike Harvey
