  The Northolt Branch Observatories (NBO; Observatory codes: Z80, Z48 and Z37) is an astronomical observatory located in London, England. NBO collects follow-up astrometry of near-Earth asteroids and other small Solar System objects. It focuses on public outreach, sharing images, videos and information about asteroids on social media.
  
  The two main belt asteroids 72834 Guywells and 128345 Danielbamberger are named after members of the Northolt Branch Observatories team.
  
  ## History
  
  Northolt Branch Observatories was founded in 2015, as an extension of the London-based Northolt Branch Astro group of local amateur astrophotographers. It is a British-German collaboration: Data is collected on-site by observers at the telescopes in England, and then processed remotely from Germany.
  
  ## Activities
  
  Northolt Branch Observatories is an educational outreach partner with NEOShield-2. It works closely with Asteroid Day and the PACA (Pro-Am Collaborative Astronomy) Project, with the goal to raise awareness about asteroids. In 2016 and 2017, NBO hosted the International Capture The Asteroid imaging contest, in partnership with NEOShield-2. The annual competition is targeted particularly at amateur astrophotographers, who rarely choose to image asteroids in favour of planets or deep-sky objects.
  
  In addition to observing Near-Earth asteroids, NBO also provides supernova confirmation and long-term follow up of comets as part of PACA observing campaigns. Examples of PACA campaigns with contributions from NBO include Rosetta's comet 67P/Churyumov–Gerasimenko, and the comets 41P/Tuttle–Giacobini–Kresák and 45P/Honda–Mrkos–Pajdušáková.
