Images and video from the partial Solar Eclipse 20 March 2015

Some images and short videos of the eclipse recorded from northwest England during a mostly cloudy morning of 20th March 2015. I used a video camera piggy-backed on my driven Vixen 102mm telescope along with a Cannon 550D at the prime focus for a few stills.  A mylar filter was used most of the time on both the scope and video camera but occasionally removed because the attenuation provided by the clouds was sufficient. Although mostly cloudy throughout the eclipse there were several intervals when the sun was not completely obscured and is when these recordings were made.

The video was shot using a Panasonic HDC HS900 camera and the first 4 still images are from that camera too. Click on any image to open gallery view.

 If you are intrigued by the birds in the images above. Here are the video clips from which they came at one tenth normal speed.

This 3 minute video is a collection of intervals when cloud cover did not completely obscure the sun during the couple of hours of the solar eclipse. It has been speeded up twenty times normal speed.

Episode 70 – India’s Deep Space Network and ISRO Satellite Centre

Indian Deep Space Network India’s space program is now over half a century old. During this time its Infrastructure has evolved. This episode looks at the current communication capabilities used to support space vehicles during launch, in Earth orbit or on a interplanetary missions.

ISRO has an extensive network of ground stations on the Indian mainland, off-shore and neighbouring countries (Mauritius and Fiji) and collaborates with Norway, Russia, USA and European countries for mission specific needs. ISRO also has ship borne resources it deploys to meet individual mission profiles.

 

ISRODish1 copy‘s flagship deep space antenna is the 32m fully steerable dish at Byalalu close to Bangalore. It was established for the 2008 Moon mission and has been the primary resource for communicating with its Mars Orbiter Mission. Byalalu is also the central site for India’s Regional Navigation Satellite System IRNSS due to come in to full operation in 2016.

This conversation was recorded in March 2014 with the then director of the ISRO Satellite Centre SK Shivakumar who had been project leader that established the 32m antenna.
