WHAT TO OBSERVE

 

1.0       Observing

 

This section will list objects and projects which interested observers may like to incorporate into their observing programs. Activities are listed under various categories.

 

The CalSKY website provides information on many objects you might want to observe. After registering try clicking on ‘Asteroids’ and then ‘This nights asteroids’.  Selecting ‘Astronomer’ gives a longer list than ‘Hobby’. Choosing an asteroid from the list gives you a mountain of data relating to that object. Asteroids at opposition and Occultations are also listed.

 

Please send a copy of all observations and images to the ARPS Director at arps@britastro.com

 

2.0       Observing opportunities

 

Note that the data published in the BAA Handbook for 2013 can also be found in Section 3.

Notes

 

(1)        Procedures which relate to both astrometry and photometry are; Timing and Star Catalogues .

 

(2)        In addition to sending your results to repositories and anyone or any organization specifically requesting data please copy them to the British Astronomical Association’s Asteroid and Remote Planets Section Director, at arps@britastro.org . This will enable reports to be produced for the BAA Journal. You may, of course, prepare your own reports or papers for the BAA Journal.

Astrometry

 

To submit astrometrical data to the Minor Planet Center (MPC) the observer must obtain an IAU Observatory Code as described on the website of the Asteroid and Remote Planets Section at:  http://www.britastro.org/asteroids/Astrometry%20-%20Obs%20Code.htm

 

Positions and orbital elements of asteroids, particularly Near-Earth Objects, change rapidly.  Such data on asteroids for which astrometry is required can be obtained from;

 

Minor Planet Center,

- NEO Confirmation Page at:  http://cfa-www.harvard.edu/iau/NEO/ToConfirm.html

- NEO Observation Planning Aid at:  http://scully.cfa.harvard.edu/~cgi/NEAObs

- Date of Last Observations of NEO's not seen in a while at: http://cfa-www.harvard.edu/iau/NEO/LastObsNEO.html 

 

Jet Propulsion Laboratory,

- HORIZONS Web Interface at:  http://ssd.jpl.nasa.gov/horizons.cgi#top

 

The Spaceguard Foundation,

- NEO Priority List at:  http://spaceguard.rm.iasf.cnr.it/servlet/PriorityListServlet

 

 

 

 

ASTEROIDS – FAVOURABLE OBSERVING OPPORTUNITIES

 

Lightcurve opportunities

 

Prepared by Richard Miles based on an analysis of both numbered and unnumbered objects in the Minor Planet Center MPCORB database by Brian D. Warner.

Asteroids are listed which at opposition are brighter than magnitude 14.5 and for which the rotation period is very uncertain or unknown.

Where a 'U' code is given as '1' or ‘1+’, the values given are based on fragmentary lightcurves and are likely to be incorrect.

Period/amplitude data are taken from the list maintained by Brian D. Warner  and Alan W. Harris of the Space Science Institute and Petr Pravec of the Astronomical Institute, Ondrejov, Czech Republic, at:

 

http://www.minorplanet.info/lightcurvedatabase.html

NEO CLOSE APPROACHES TO EARTH

 

Prepared by Richard Miles from data on the Jet Propulsion Laboratory's Near Earth Object Program website at:

 

http://neo.jpl.nasa.gov/ca/

 

It lists asteroids predicted to pass within 0.05 AU (about 7.5 million km) of the Earth during 2013 (as of 2011 Dec 24).  Newly-discovered objects may be added to the list available via the JPL NEO site, so do check this for recent updates.  The Nominal Miss Distance is given in Lunar Distances (LD) and Astronomical Units (AU).  The apparent Elongation and Declination are geocentric.  Ephemerides should be obtained near the time of observation from the MPC via its Minor Planet and Comet Ephemeris Service at:

 

http://www.minorplanetcenter.net/iau/MPEph/MPEph.html

 

For your local ephemerides, choose a location or observatory near your site.  Note that the positions of some objects may be subject to significant uncertainty.
