Giant Filament-Prominence This giant filament prominence was visible on the SE limb on 27 Jan 2011. I made this movie at 1 minute intervals from 1816-1943 UT with the Tak 102, double stacked 75mm, and the DMK 41AU04. A new AR may be forming, and hot plage can be seen surging around a small area.

Giant Filament Prominence
January 27, 2011Grains in the Chromosphere
January 26, 2011Here we see 2 movies made from the light of the Calcium K line. It shows the middle levels of the chromospheres, and chromospheric grains, or bright points, are easily seen as small grainy flashes. Both movies were captured at 1 minute intervals using a Lunt CaK Diagonal on the Tak 102. The 31AU03 was used [...]
Hi Res Hydrogen alpha Movie AR1147-1149
January 26, 2011I received a new DMK CCD imager, the DMK 31AU03. It has a much larger chip, but half the frame rate of the 41AU04. I tested the new device on 24 Jan 2011 and made this time lapse movie at 1 minute intervals from 1816-1956 UT. The clip shows AR1147-1149 near the limb, and I [...]
Hydrogen alpha Time Lapse Movie of an Emerging Sunspot
January 24, 2011On 21 Jan 2011, AR 1147 had a new neighbor. AR 1149 was poking its magnetic flux tubes into the photosphere and chromospheres. The emerging sunspot crackled with flares. For 3 hours, the area pulsed with B and C class flares that were easily viewed as I watched on the computer screen. I made this [...]
Filament or Prominence?
January 23, 2011Both are the same. Filaments seen on the limb in emission are called prominences, while a prominence on the disc in absorption is called a filament. This movie shows a filament extending from the disc to the limb, where it can be seen as a prominence. A dark filament with a developing filament channel is [...]
The Big Swirl Prominence 22 Jan 2011
January 23, 2011The Big Swirl 22 January 2011 This solar prominence was captured at 1 minute intervals on 22 Jan 2011 from 1847-2157 UT. This prom exhibited a lot of movement, so I let the system run for a 3 hour session. Much of the material that comprised this prom flowed back into the chromosphere. Plasma in [...]
Hydrogen alpha Movie of a Solar Active Region
January 21, 2011This movie of active region 1147 was captured at 1 minute intervals on 20 Jan 2011 from 1748-1927. The double stacked lunt 75mm hydrogen alpha filter was used on the tak TSA 102, and a cemax barlow was screwed onto the nosepiece of the DMK. The AR exhibits small areas of emerging flux, and a [...]
Running Penumbral Waves and the Horse Head
January 20, 2011Here is a time lapse movie of solar active region 1147 captured at 1 minute intervals on 18 January 2011 from 1841-2110 UT. Quite a bit of flow can be seen in the sunspot penumbra (click on the image to start, this will take a minute or two to download). Take a close look at [...]
A Very Large Solar Prominence
January 19, 2011This large quiescent solar prominence was visible on the southwest solar limb on 18 jan 2011. it shows downward motion of plasma. here are a few quick facts about solar prominences gleaned from the nature of solar prominences by tandberg-hanssen. a prominence can be defined as “an object in the chromosphere or corona that is denser [...]
AR 1142 and a Neutral Line Filament
January 2, 2011here is the first solar time lapse of the 2011 year. the sun has been showing increased activity as the current solar cycle progresses. many solar features are now visible on what was once a blank sun. this movie shows an emerging flux region (EFR) that was designated AR1142. it was captured on 1 jan 2011 from 1727-1927 UT.
