Frantic upheavals


A large and powerful sunspot group (AR1654) has a dynamic and twisted magnetic field that we followed for six days (Jan. 9-15, 2013). The interactions of a pair of regions (actually two sunspot areas when viewed in filtered light) produced numerous smaller flares, while the magnetic field lines looped and snapped and flashed almost continuously. The detailed action was captured in extreme ultraviolet light.

This art [astronomy]which is as it were the head of all the liberal arts and the one most worthy of a free man leans upon nearly all the other branches of mathematics. Arithmetic, geometry, optics, geodesy, mechanics, and whatever others, all offer themselves in its service.

The year 2013 has started with a launch of a Chinese Sky lantern into the Southern night sky from a coastal village in the Eastern Cape, and what a perfect launch it was.. This single exposure shows a complete life cycle of the lantern from the moment it was fired till complete burnout.

For several days huge sunspot 1890 was "aimed" directly at Earth posing the thread of Gamma rays outbursts.

Clear view of the eclipse was obstracted by a small cloud only for couple of minutes.

South african observers in Western Cape had the best view of Juno Spacecraft approaching the Earth during "slingshot maneuver designed to gain velocity for Juno's long trip to Jupiter " (http://www.spaceweather.com/). Greg Roberts shares few of his images, obtained during the event.

2013 ETA AQUARID METEOR SHOWER reached it's peak on May 5-6th and was very spectacular. On May the 5th at 05:53 am (SAST) the international Space Station also could be seen crossing the meteor shower radiant, making the observations even more special:

 

 

 
 

 

 

 

     

 

 

 

Just as I was busy with the final camera settings at 05:51 a very bright fireball crossed the sky very close to where the ISS trail can be seen in this image, but.. I wasn't ready for it! Half an hour later, at 05:28 another smaller fireball burnt down right above me, leaving a wonderful greenish trail, illuminated by the moon (see the image below). Just in one hour I have seen three fireballs and few dozens of meteors, what a morning it was! Waking up at 4 am and going outside, where the temperature happened to be just two degrees above zero, was a very rewarding exercise.

 

 

 
 

 

 

 

 

 

 
 

 

 

 

 

 

I took my first ever photograph of the International Space Station on August 30th, 2009. Only 3.5 years later I finally caught the ISS transiting the Sun.

I had it all- random cloud obstructed the Sun just for 5 minutes exactly when the transit should have taken place back in 2009; I stuck in traffic on the way to the site in 2010 and arrived just 1 minute after the transit; I've left the camera adapter for the telescope at home in 2011; In 2012 I was ready in time, but it was a low transit, the ISS never showed up; another attempt failed when few minutes before the transit my telescope focussing mechanism just broke.

This time everything was just fine- the sky cleared up after rainy morning, the transit time, predicted by CalSky was accurate within a second, and I actually saw the ISS with my eye through the camera's vewfinder between the frames- it was spectacular!

This was the only chance for me to photograph the Comet PanSTARRS from Johannesburg:

For few days the Comet C/2012 F6 (Lemmon) presented a good photographic opportunity while appearing close to a bright globular star cluster Tucanae (47)

The sunset. As the Sun approaches the horizon, there is a lot happening with the sunrays before they reach our eyes or the camera. The rays of light are affected by many optical effects, such as absorption, reflection, refraction, abberration. And most of change is happening when the rays are travelling through the turbulent Earth's atmosphere.
