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:	Tests of the '3rd order reflections' (ORD3) operating  mode have been performed twice  (on Nov 14 18:55:16 UT  and 17 18:40:45 UT) with  partiall success. The mode needs more  tweaking. Except these times, the now 'standard' new mode  has been used. The settings are below.
Calibrations made:	No calibrations  made
ADS Settings:	HV: Det. A - 1450 V, Det. B - 1389 V.  ADS  are  below.

On orbit 7213 the COMP switched automatically to  the backup unit, most probably due to so called "Single  Event Upset". After next reset, the system returned back  to normal.

                    
Data gaps due to missing telemetry: ~12 hours.

Examples of Well-observed Events:

 15 April 2002, 02:51 UT

As we are running out of time, today we just present one of many events which has been well covered by RESIK. We have selected an interesting, short duration disk flare with fast rise and decay.
The event has been observed by RESIK using constant DGI = 10s.

 

	Date:	15 April 2002
	Start, Max, End [UT]:	02:46:00, 02:51:00, 02:55:00
	GOES Importance:	C9.8
	Duration:	~9 min.
	Ha Class:	SF
	NOAA AR association:	9893
	Location (EIT):	N21 W68

Below, spectrum integrated over this flare is presented.

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.
