MARCH - APRIL - MAY 2004

March 1st 2004

Quite poor seeing. In the EZs a "South equatorial disturbance", the most noticeable phenomena of the 1999-2000 apparition, is now visible again. Left : IR image, right : UV image?

March 2nd 2004

A very good night with many fine images. In particular, a good UV image has been obtained thanks to the good seeing. The STB dark spot is not visible in infrared.

March 6th and 9th 2004

Two correct nights who allows one to study the hemisphere preceding the GRS. On march 6th a 1-micron image is taken : it already presents many characteristics of the CH4 absorption in near infrared : the higher clouds (GRS, EZ...) are brighter.

13th and 16th-17th March 2004

The 13th image is made with a CN212 of a friend during a regional star party. On march 16th-17th, we have a good view on the hemisphere that precedes BA.

April 1st, 9th, 15th 2004

The two first images are made during barely corrects nights. The 9th, the SED passes just north of the GRS and thus is not visible, but it's going to become a quite conspicuous "rift" in SEBn in the following days. On the 15th seeing is very good. Note the very dark EB in violet and UV light.

April 21th 2004

The last observing night with the C14. The images are not superb but there is a good multispectral set. From left to right IR780, UV, IR1000.

April 25th 2004

Certainly the best observing night of the season ! From left to right, RGB, Violet, UV. Even the quality of the UV image is excellent for that wavelenght.

The images show the SEQ in various wavelenghts.

May 9th 2004

Again a good night. From left to right RGB, IR700, UV.

May 7th, 11th, 18th 2004

Some last images.

On the 11th, just after sunset the seeing was excellent, as often in my location during spring (but seeing degrades rapidly thereafter). The integrated light image (IR-cut filter) is the best example of the powerful RAW mode (5 fps, 400 raws stacked).
