About This Club

Pro-Am science of comets: a place to learn and share observations and analysis.

  1. What's new in this club
  2. This shows the wide variety of comet orbits! https://www.youtube.com/watch?v=7l16fVKKURs
  3. Great, thanks Mark ? We can keep adding here and I'll consolidate at intervals. Helen
  4. Helen I also use this website - http://cometchasing.skyhound.com/
  5. Welcome to the Hairy Astronomers Club! Sorry, the Hairy Star (Comet) Club ? This is the place to be if you fancy contributing to science by observing, analysing and reporting comet positions and brightness. We'll be developing guides and tutorials in conjunction with some BAA colleagues, to build competence and consistency. That way the results should be useful to researchers as they try to understand better the enigmas that are comets. We'll be learning together, which should be fun! And ultimately our contribution may be cited in research (hopefully in mine!!). Over the coming year or so we expect good targets to be comets 46P, 29P, 17P and then 67P (Rosetta's comet). We'll put up details of where the comets will be when, and what observations will be most useful. We can then also share observations and start building combined light curves ? Exciting times ahead ? Helen
  6. Here are some good sources of information on what comets are visible. Comet Watch: http://www.cometwatch.co.uk/ Heavens Above: https://www.heavens-above.com/Comets.aspx?lat=0&lng=0&loc=Unspecified&alt=0&tz=UCT JPL: what is observable (comets and asteroids) from your location https://ssd.jpl.nasa.gov/sbwobs.cgi
  7. Minor Planets Centre: The place for all the core data on any comet (or asteroid) https://www.minorplanetcenter.net/iau/mpc.html Jet Propulsion Lab JPL Small-Body Database Browser https://ssd.jpl.nasa.gov/sbdb.cgi#top Including Orbits like this: https://ssd.jpl.nasa.gov/sbdb.cgi?sstr=46p;old=0;orb=1;cov=0;log=0;cad=0#orb Horizons : detailed ephemerides / positions https://ssd.jpl.nasa.gov/horizons.cgi New Comets: BAA https://www.ast.cam.ac.uk/~jds/coms18.htm
