[BAA Comets] Comets-disc Digest, Vol 44, Issue 15

Hi Richard and Denis,

Yea the BAA is by far the most productive organisation, and your analysis
Denis is probably correct.

But there are a couple of other issues that I think contribute as well.

1. All observations which have been imported previously to COBS from the
BAA archives have received the BAA association affiliation, indipendent of
observer nationality and the identity of the originally ICQ-reporting
association.

When we imported the ICQ archive we found that about 15% of the
observations were already stored in COBS (112 939 of ca 130 000 ICQ
observations). For these, the original affiliations were not overwritten
and thus the affiliations remain those of BAA.

ICQ observations made by already known observers received the affiliations
previously stored those observers, but new observers from the ICQ archive
received ICQ affiliation (therefore 37 000 ICQ observations in COBS).

As an example, in the case of Swedish observations, the total is now 1129,
of which 520 are affiliated to SAAF, 532 to BAA and 77  to ICQ. All these
observations were originally reported to the ICQ by the country
representative and all were SAAF members, so when we have got all
affiliations set right, the number for BAA will decrease somewhat.

2. Also, I found something I had not previously realised (but which Clay
Sherrod has reported), since it has been impossible to overlook the content
of the ICQ archive. Namely, a lot of (Swedish) observations
apparently never ended up in the ICQ archive, even though they were
submitted. One blatant case is Hale-Bopp for which only 14 observations
Swedish observations are present, though the total number made is ten times
as big.

So one significant remaining task is to go through our own archives and
upload the missing observations. Thus the effort that Jonathan has put in
to find and report historical BAA observations is likely crucial to fill in
all the gaps.

Probably many more observations are still in national/association/personal
archives around the world and need to be found and reported (again). This
is an importsnt task for national coordinators/directors.

But in any case, even if the country/association affiliations in COBS can
not presently be fullt trusted and we know for sure that there are
unreported observations out there, at least the observations which
are available for scrutiny have been assigned correct observer
identifications (and can be traced)  This is a good thing!

Best wishes,

Johan
