Observing comets

For the beginner: Details of a comet and good and bad observations.

Some hints and tips on how to improve your observations.

Christopher Taylor contributed an article to the section newsletter which describes how to carry out simple spectroscopic studies of comets.

The Edgar Wilson Award has been instituted for amateur comet discoveries.

Maik Meyer has a catalogue of comet discoveries. Don Machholz "A decade of comets" gives an account of discoveries between 1975 and 1984, and Don also has spreadsheets giving further information on amateur discoveries to date. He also provide an account of his searching in a message posted on 2008 May 6.


Current meteor showers

Meteors are the debris of comets and a meteor shower occurs if a comet's orbit intersects the earth's orbit. It is always worth watching for sporadic meteors as you never know when an outburst from some minor shower may take place. Several showers have produced enhanced returns over the last few years. [Updated 2007 September 11]

CÚdric Bemer notes that the Earth passes 0.005 AU inside the orbit of comet 2006 VZ13 on 2008 May 27.1 (solar longitude 66 degrees) and that there may be a possibility of a meteor shower. The radiant is around RA 330 +16. Interestingly Peter Jenniskens lists the gamma Delphinid shower, which has a broadly similar orbit and is active from June 1 - 20 from a radiant around RA 320 +12. Jenniskens gives a possible outburst on 2013 June 11.

The 2007 Orionids gave an unexpectedly strong return, with ZHR of over 50.

The meeting was held in Milton Keynes at the Open University. Other speakers included Neil Bone, Alan Fitzsimmons, David Hughes, Monica Grady, Andrew Elliot, Iwan Williams, Nick James, Graeme Waddington and myself. Programme.
    Meeting report.

    The "Meeting on Asteroids and Comets in Europe", MACE 2003, was held from May 1st to 4th at the Mallorca Observatory, Costitx, Mallorca, Spain.

    There was an RAS discussion meeting on Cometary Science at the Launch of Rosetta on 2002 December 13 at the Geological Society Lecture Theatre, Burlington House. For more details see the RAS Meetings Calendar. An account appeared in the Aril 2003 issue of The Comet's Tale.

    The Asteroids Comets Meteors (ACM2002) conference was held in Berlin from July 29 to August 2, 2002. Information on the conference is available at the meeting web site. Notes from the meeting appear in the October 2002 issue of The Comet's Tale. MACE 2010 was held at Visnjan/Tican, Croatia from May 21 to 23.

    There was a Section meeting associated with the BAA Ordinary meeting on Saturday 2002 February 23, notes from the meeting are included in the April 2002 issue of The Comet's Tale.

    A recent professional meeting was the "5 Years After Hale Bopp" conference held in Tenerife January 21-25, 2002. Information on this conference is available at the meeting web site.

    The second International Workshop on Cometary Astronomy was held in Cambridge over the weekend following the total eclipse on 1999 August 11. Details of IWCA2.

    The 2010 BAA Exhibition Meeting took place in London on June 26. The comet section posters showed the work of the section and highlighted Rolando Ligustri's images.


    Publications

    The comet section 'Observing Guide to Comets' (2002 edition) is available from the BAA Office at a cost of GBP 3.50, or at selected BAA events for 3.00. Overseas and UK observers can now purchase items from the BAA Sales desk using credit cards. The Guide describes all the details you need to record to make a scientifically useful observation and also helps beginner observers to locate and view comets.

    The Section Newsletter 'The Comet's Tale' is published once a year, usually in early January. Only the pdf version is now produced and this is available for download from these pages. The latest issue is 2014 January. Back issues for April 1999, October 1999 , April 2000 , October 2000 , April 2001 , October 2001 , April 2002 , October 2002 , April 2003 , October 2003 , April 2004 , October 2004 , April 2005 , October 2005 , April 2006 , January 2007 , December 2007 , December 2008 , January 2010 , January 2011 , January 2012 , January 2013 and January 2014 are available in pdf format.

    The ICQ has published a very comprehensive guide to observing comets, which covers historical observations and theory to degree level. Further details are available from the ICQ pages. This is now out of print, but may be published commercially in the near future. Some recent ICQ articles are published on line. A new initiative springing out of the ICQ is the Cometary Science Center, which in the long term will become a repository for information about every observed comet.

    Pamphlet on the George Alcock memorial plaque Martin Mobberley has created a web page on George Alcock.

    There is an interesting perspective on the Kuiper Belt and Comets written by Dave Jewitt.  Paper on Caroline Herschel's comets released on arXiv.  David Seargent has published an e-book on sun-grazing comets.  

    The Section publishes an annual report each year in the BAA Journal. The following reports are available on line: 2003 / 2002 / 2001 / 2000 / 1999 / 1998 / 1997 / 1996 / 1995 / 1994 / 1993 / 1992 / 1991 / 1990. Some additional historical information about the Section can be seen from this list of Section Directors, Keedy Award winners and Newsletter Editors. This detailed history is taken from the BAA Publications 'The first fifty years' and 'The second fifty years'.

    The December Journal usually includes an update on the comet prospects for the coming year. Analyses of comets appearing in any year appear on a regular basis. A report on the comets of 1991 appeared in the August 1997 BAA Journal. Unfortunately the figures for the orbits of comets 97P and 103P given in the paper are for the current orbits, not as they were in 1991. The correct figures are given in the links above.

    This index to Section publications gives a brief listing of the contents of the Section Newsletters and papers published in the BAA Journal. [Updated 2002 October 14]
