SATURN 2012
Here's a new season for
Saturn. Last year was very exciting because of the huge storm in the
Northern Hemisphere. These images are north up and were taken by my C14 mounted on an AP900GTO mount with a Point Grey Research monochrome Flea3 (ICX618) camera. Chroma Technology LRGB filters were used to make the color image. For info on Saturn's belts and zones please click this link. You can also see my past images of Saturn at the ALPO Japan Kansai Branch site.

2012 Weather had been terrible here for the past week because of Super Typhoon Guchol. The skies finally cleared today but transparency was poor. The northern hemisphere of Saturn has a very reddish hue on it's belts. The zones of Saturn is greenish. Note the white spot on the NNTZ.

2012 Seeing was okay this evening. Note the bright white spot on the NNTZ. Is this an Electrostatic Disturbance. Note the dark barge just right next to this white spot. The NNTZ is very bright green.

2012 I have been out for over a month because of my trip to the USA. I had a great time at the NEAIC/NEAF at Suffern, NY. And I saw a wonderful Annular Eclipse at Karannaville, UT last May 20. Some changes in my system, I am now using a Chroma Technology LRGB filter. These filters are great as they are very sensitive. Color is also better than my old filters. Saturn looks quiet today. Note some white spots at the NNTZ and what seems to be a white streak on the NTB. There are also some white spots on the NTZ. The images on the right are 5 image derotated each. While the image below is the derotated image of all my capture today.

2012 I had to image Saturn early today to catch the NED. Seeing was unstable. The NED is the white spot close to the CM above the green NNTZ. A few days more before opposition. The rings are brightening.

2012 Seeing was better than last night but still unstable. Finally caught the NED. This confirms Anthony Wesley's image. The position of this disturbance is at CM3: 315 and Lat: 54. Contrast is very low probably because of the Seeliger effect which is brightening the rings! The image below shows better contrast on the storm. I derotated 40 minutes of data. |

2012 Seeing wasn't great this evening. It's a few days from opposition and the rings are now displaying the Seeliger Effect! Saturn's northern hemisphere is reddish this year. The green belt is where the Electrostatic Disturbance appeared last year. Note that the southern edge of this belt has some white patch features. The Cassini Division can be seen around the planet.

2012 Seeing was very unstable this morning. Note the remnant of the Northern Electrostatic Disturbance. It's a small white cloud at the NNTZ at the CM of the second image. Note the dark belts at the north polar area. A hint of the Encke division can be seen.

2012 Seeing was very unstable today. I used Winjupos derotation for these images. The Northern Electrostatic Disturbance can be seen in these images embedded on the green belt. The northern hemisphere of Saturn is reddish. While the pole is greenish. The rings are getting wider. The Encke Minima can be seen on the edge of the ring.

2012 Here are some of my first images of Saturn this season. Transparency was very poor this morning. It was tough to get enough frames. The rings of Saturn are getting wider. Note the bright green band in the northern temperate area. It is hard to make out the NEB but there seems to be a wide reddish area on the northern hemisphere of Saturn.
