MAI-75 SSTV Expedition 65 August 6&7

The Moscow Aviation Institute (MAI) did a couple of quick experiment sessions of SSTV during parts of August 6 and 7. The setup started at 10:50 UTC on August 6 and transmissions stopped around 19:10 UTC. The activation on August 7 started this morning about 09:50 UTC and ended 17:30 UTC. ISS setting : the usual PD120 format on the standard downlink frequency of 145.800 MHz.

I used the 70m high antenne with webSDR "Nürnberg skyscraper" and MMSSTV software.

I could download 7 pictures of which one was very poor quality. The quality of the others are good but none of the pictures are perfectly alligned.

Solar Astronomy Book

This week I received the new english book "Solar Astronomy" which is a translation of the popular "Astronomie Solaire". I was able to get a signed version of the book.

The webpage tells the following :

Solar Astronomy is a wonderful introduction and reference for anyone interested in our star the Sun and particularly anyone interested in participating in the adventure of understanding the Sun by observing it themselves.

We live at a particularly exciting time in the study of the Sun with major, new space-based and ground-based, long-term full-Sun and high-resolution observations returning spectacular images and measurements, advancing our knowledge of existing challenges and revealing new phenomena of this fascinating dynamic physical laboratory, exemplar of all of the stars in the universe, and source of essentially all of the energy that makes life possible, ever changing on timescales from seconds to decades.

This all-encompassing, modern, and authoritative collection addresses the latest developments in optical, radio, and eclipse observations of the Sun and should be of broad appeal to the solar physics pro–am community, and beyond, providing the reader with the understanding and tools to be an active participant in the fantastic progress being made in our enjoyment and exploration of our neighborhood star.

In presenting the background and the tools for moving forward in our understanding and appreciation of the Sun, this book also makes available to the world the accomplishments of modern “amateur” solar physicists.

My congratulations to Christian Viladrich and colleagues for this beautiful work sharing their passion for observing the Sun, up close and personal, and paving the way for others to join in the adventure.
