CBAT
Discovery of many kinds of transient astronomical phenomena (e.g., comets, novae, supernovae, etc.) should be reported to the CBAT. The Bureau is responsible for assigning designations to comets, supernovae, and Galactic novae. Sometimes reports are received of such objects that contain observations on only a single night (or sometimes more than one night), needing confirmation before formal announcement and designation on IAUCs (and sometimes CBETs). Below are listed temporarily such unconfirmed observations, so that interested observers may attempt confirming observations. Please report any observations (negative or positive) promptly to the CBAT at e-mail address cbat@cfa.harvard.edu.
Meteor(ite)/fireball reports should not be reported to the Bureau, but to
the Fireball Data Center of the International Meteor Organization
(e-mail: idac@imo.net).
Discoveries of new minor planets should be reported to the Minor Planet Center.
A listing of the information that one should include in any discovery report concerning comets, supernovae, novae, outbursts of variable stars, or features on planetary surfaces is available.
If you wish to report a discovery you may report it in this
manner. Please ensure that you
have read the documentation on what information you should include in
your report --- incomplete reports may be ignored.
You should e-mail a report directly to
cbat@cfa.harvard.edu.
Please read this to see how to represent non-standard characters.
The unconfirmed observations are listed below in plain ASCII text in essentially the 80-column format used for MPC astrometry, for columns 16-71 -- the exception being that one should put the galaxy designation in the first 14 columns for supernovae candidates (psn for "possible supernova"; sn for "supernova already confirmed spectroscopically"), the 3-letter constellation abbreviation for novae and other non-solar-system candidates, and "poss.comet" for comet candidates; and columns 73-80 are used for supernova-suspect offsets in arcsec from the host galaxy's center as follows:
70 80 123456789 xxxEyyyN
where 'xxx' is the rounded-even digits (flush right) for arcsec (NOT seconds of time) of right ascension, the 'E' would be used if the supernova is east of the galaxy center (otherwise 'W' for west), 'yyy' is the rounded-even digits (flush right) for arcsec of declination, the 'N' would be used if the supernova is north of the galaxy center (otherwise 'S' for south). In column 71 after the magnitude, use `U' for unfiltered CCD, `T' for technical-pan film, `V' for V magnitude, `R' for R or red magnitude, lower-case `v' for visual magnitude, etc. NOTE: In Oct. 2004, as per interest by observers, we added two columns to aid observers in judging the quality of the candidates below: (1) in column 83 is given a number from 0 to 9, specifying the number of previously designated (and not later retracted) supernovae discovered by the same observer (as listed in the CBAT webpage file of supernovae); the number 9 signifies 9 or more discoveries. (2) in column 85 is the number of days between known frames taken by the discoverer (and others, if relevant), with a nine (9) indicating nine or more days, a zero (0) signifying 0.5 day or less, and a dash (-) indicating only a single frame (a blank indicates that this datum is unknown). NOTE that we are discontinuing our policy of posting anything here based on single images: observers *must* report that two images confirm the reality of the object (to rule out imaging flaws), and it is preferred that images be taken at least 20-30 minutes apart (for telescopic imagery; 1-2 hours for smaller-scale camera-lens imagery) to rule out such things as minor planets, in order for objects to be posted here.
