   Atlantic Anomaly  has expanded by an area nearly half the size of continental   
   Europe since 2014.   
      
      
   Earths magnetic field is vital to life on our planet. It is a complex and   
   dynamic force that protects us from cosmic radiation and charged particles   
   from the Sun.   
      
      
   The weak field South Atlantic Anomaly was first identified southeast of South   
   America back in the 19th century.   
      
      
   The South Atlantic Anomaly is not just a single block, says lead author Chris   
   Finlay, Professor of Geomagnetism at the Technical University of Denmark. Its   
   changing differently towards Africa than it is near South America. Theres   
   something special happening in this region that is causing the field to   
   weaken in a more intense way.

   Is Low Earth Orbit Getting Too Crowded?   
      
   Hundreds of satellites may soon be flying in orbital regions that are already   
   too packed to allow safe and long-term operations, a new study suggests.   
      
      
   The study found that, while in 2019 only 0.2% of satellites in Earth orbit   
   were forced to perform more than 10 collision-avoidance manoeuvres per month,   
   that percentage had risen sevenfold by early 2025. It means that some 340   
   satellites spend a lot of time dodging debris and other spacecraft.   
      
      
   Moreover, the satellite population is set to keep growing. While in 2019   
   about 13,700 objects (including space junk) zoomed around the planet in low   
   Earth orbit (LEO), at altitudes below 2,000 kilometres, that number has since   
   risen to 24,185 objects in 2025, an increase of 76%, according to the study.   
   By the end of this decade, some 70,000 satellites may reside in LEO,   
   according to industry growth predictions.

   A constellation of classified defence satellites built by SpaceX is emitting   
   a mysterious signal that may violate international standards.   
      
      
   Satellites associated with the Starshield satellite network appear to be   
   transmitting to the Earth on frequencies normally used for sending commands   
   from Earth to satellites in space. The use of those frequencies to downlink   
   data runs counter to standards set by the International Telecommunication   
   Union.   
      
      
   Starshields unusual transmissions have the potential to interfere with other   
   scientific and commercial satellites, warns Scott Tilley, VA7LF, an amateur   
   satellite tracker in Canada who first spotted the signals.

   WW SPECIAL INTEREST GROUPS ---- MEDICAL.   
      
   Amateur radio is for everyone, as we know, but not everyone has the same   
   access to what they need to succeed. Some operators, or those who wish to get   
   their license, have disabilities that can get in their way. Jeremy Boot   
   G4NJH, reporting for NewsLine tells us about an effort to shine the spotlight   
   on this situation - and the need for change.   
      
      
   "One of the greatest challenges of amateur radio ought to be getting a rare   
   DX, logging an all-time-new-one or mastering a new skill or new operating   
   mode. It should not be the act of trying to get on the air itself.   
      
      
   To ensure that radio amateurs with disabilities have the same chance at all   
   the other challenges and adventures, the Program for Disabled Radio Amateurs   
   in IARU Region 1 is encouraging a celebration on and off the air to reflect   
   ham radio's welcoming spirit.   
      
      
   This event will take place on the 3rd of December, which the United Nations   
   has declared to be the International Day of Persons with Disabilities. In an   
   announcement about the programme, its coordinator Riri Azrak OD5RI encourages   
   ham radio societies to plan awareness events, nets or special events using a   
   special call sign incorporating the letters PDRA. Hams are also being urged   
   to identify and support radio operators with disabilities or persons with   
   disabilities who are seeking their licence.

   SKYNET-1A WHERE ARE YOU?   
      
   A military spacecraft launched 56 years ago was moved from its orbit  and   
   nobody is quite sure who did it, or why.   
      
      
   In 1969 the UK launched Skynet-1A, a military communications satellite placed   
   in orbit above the east coast of Africa in order to relay information to   
   British armed forces. It stopped working due to hardware issues around 18   
   months after it started operating, and the spacecraft was left to the laws of   
   physics to orbit the Earth  it is now the oldest UK spacecraft still in   
   space.   
      
      
   In the 1970s, when the satellite was still closely tracked, it was in a   
   geostationary arc at a longitude of around 40 East, where it remained when it   
   was decommissioned. Such orbits are subject to gravitational perturbations by   
   the Sun, Earth and Moon.   
      
      
   If Skynet-1A had failed at its operational location of around 40 East, we   
   would now expect it to be oscillating by +/- 35 degrees either side of 75   
   East, satellite-system engineer Dr Stuart Eves explains in a blog post for   
   The Global Network on Sustainability in Space.   
      
   Except that it isnt."   
      
   According to the UK Registry , Skynet-1A is currently sitting very close to   
   the bottom of the other well at 105 West, oscillating by just a couple of   
   degrees.
