In the display above (click to enlarge), the solar X-ray fluence seen by RESIK (black points)  is plotted atop GOES red line. Only periods with good spectral measurements are indicated. The total number of good spectral measurements is given in the title line.

New mode:	The '3rd order reflections' (ORD3) operating  mode is used as a new 'standard' mode. More detailed description will be given next week. Other than (ORD3) settings are given below
Calibrations made:	No calibrations  made
ADS Settings:	HV: Det. A - 1450 V, Det. B - 1389 V.  ADS  are  below.

Forthcoming Solar Eclipse on 4th December 2002
as seen from CORONAS-F

This plot shows the variation of an angular separation between the Moon and the Sun centres as seen from the CORONAS-F satellite. It was constructed based on Zbigniew Kordylewski calculations from the CORONAS-F orbital ephemeris of Dec. 4, 2002. The red heavy line plotted shows periods when CORONAS-F is outside the Earth's shadow. The horizontal dotted line is plotted at the level corresponding to the sum of the solar and lunar radii. Thus every point below corresponds to a partial eclipse. The angular separation does not get to zero on this date (the minimum separation being ~12 arcmin), so CORONAS-F will miss a total eclipse, even though it gets four partial ones.

The first eclipse period will be seen somewhat eastward  from Brazil towards the Antarctica.
During this period the SAA radiation anomaly may cause RESIK detectors being switched-OFF. At the time of the deepest eclipse around 08:40 UT, the satellite will be travelling from Antarctica towards Australia and China.

The report presented  has been done in "real time" and so it may contain jargon, blunders, or trivialities. We do not have also an English native speaker in our Wroclaw group! We would be happy to discuss problems mentioned above in more details  if necessary.
RESIK data are in the open public domain and can be requested from: http://surfwww.mssl.ucl.ac.uk/surf/data_request.html.
