- Halley's comet is still observed! in March 2003, at the distance of
Neptune. This was also the "Astronomy Picture of the Day" on Oct.3.
I had also observed that comet in 1994, as it
passed the halfway mark (January 1994): observation of the
faintest solar system object ever observed. [at that time]. In 1991, I
detected a majour outburst on the comet - which should have been quiet
at that time. This outburst created some waves in the public. For
instance, a lady contacted me to ensure me that this was a direct
cause (or was it a consequence?) of the Gulf war. Also, a journalist
concluded that the comet had completely exploded (which in turned
french in this example).
- Comet Hale-Bopp is still very active, esp. considering the
distance at which it is now. We observed it at the 2.2m at ESO in
Mar.2001; here is a nice color
image (and is also available in
elsewhere...). It was also an
Pic. of the Day".
- The object 2000 OF8 was discovered as an asteroid. We found out
that it is really a comet
The Trans-Neptunian Object 1996 TO66 has been extensively
observed; we obtained many interesting resulst on that object,
including its rotation period. This is described in
Press Release, and in more details in one of
- A strange supernova, sn 1998 bw, which seems to be related
to a Gamma Ray Burst (May
98). An ESO
Press Release has been published on that object.

Observations of Comet Hale-Bopp.
Hale-Bopp page contains plenty of info and links about that comet;
for nice pictures, check out

Comet Hyakutake (March 1996):
acrobatic observations of this nice comet with a great telescope and a

its discoverer page.

TG2 (October 1994): one more TNO (only about 60 were known at that time), but I
discovered this one :-)

an ESO/MIDAS package for astrometric calibration of scientific image (plates
and CCD); it can get its USNO/A1 standard stars automatically through the
an ESO/MIDAS package for photometric calibration of CCD images, with
quasi-automatic identification of Landolt's stars, and interactive
edition of bad points.
a web-tool to monitor the conditions at ESO/La Silla. It also exists for ESO/Garching, at
MeteoMonitor - Garching.
Astrolabe Generator, a web-tool to
produce "astrolabes" for your site (updated version at eso.org - The
one at IfA is outdated).
Airmass Plots, a web-tool to produce airmass plots for a list of object over a full night. This is the tool that used to work on the La Silla SciOps pages.
Observable comets, compute ephemerides for all comets, and select them according to various criteria.

On this page, you will find the whole,
email exchange constituting the Car 42 Saga. This is part of
the ESO folklore, probably of no interest for outsiders...
Marie-Claire, my wife, has her own page
at the Canada-France-Hawaii Telescope,
with plenty of palmtrees and aloha. Note that she left CFHT for
Gemini, where she worked until 2009.
There was a nice article about her in
the July 98 "Ciel & Espace" (sorry, no English version).
