TELESCOPE: WHT

INSTRUMENT: ISIS double spectrograph
      Blue arm: R300B l/mm grating, EEV12 detector, covering 3000A
      Red arm; R150R l/mm grating, TEK4 detector, covering 3000A
      Dichroic at 5700
      Red blocking filter for red arm at 4950A
      Slit width was 1"-1.5" the first night and 1.5"-2.5" the third night

OBSERVERS: Francisco Carrera (IFCA) &  Laurent Mirioni (OAS)

TECHNICAL REPORT:  No technical problems to report

WEATHER: Weather was good (perhaps some wispy clouds) the first night
until UT03:40, when humidity rose to 100% in 10 minutes and we have to
close the dome.

Seeing was about 1" at the beginning of the night, worsening to about
1.5" at bout UT02:33. We used a slit of 1" at the beginning of the
night, changing to 1.5" after UT02:33.

The second night humidity was 100% the whole night

The third night humidity started at 100% but went down and we opened
the dome at about UT04:25. We had to close it again at ~ut06:20 due to
high humidity.

Seeing was about 1.6" at the start of observations (UT04:30) degrading
rapidly to 2.5" and 4.6" at UT06:14.

The fourth night the weather was very good with good
transparency. Seeing stayed below 1" most of the night.

REPORT

We intended to concentrate in finishing up fields, mainly Mkn205 and
G133. After those the main priorities were GRB001025 (GP mainly clear
counterparts) and EQPeg. In the end we could only "finish" Mkn205,
advance in G133, and start Mkn3 and GRB001025.
