We are pleased to report that as of October 31, 2002, RHESSI has
achieved its Minimum Science Requirements:
1. Perform hard X-ray (greater than 20 keV) imaging spectroscopy of
solar flares with better than 4 arcsecond spatial resolution and better
than 3 keV energy resolution.
2. Perform high resolution (better than 3 keV FWHM at l MeV)
spectroscopy of gamma-ray lines in solar flares.
3. Obtain observations of at least a hundred hard X-ray flares and ten
gamma-ray (greater than 300 keV) flares.
RHESSI has performed imaging spectroscopy of hard X-ray flares from
3 keV upward, with 2.3 arcsec resolution, and ~1 keV energy resolution.
It has obtained high resolution spectra of gamma-ray lines in the 23
July 2002 flare. On October 31, 2002, it detected its tenth gamma-ray
(>300 keV) flare. It has also detected over one thousand hard X-ray
(>25 keV) flares.
All systems are operating nominally, and we are looking forward to
eventually achieving the Baseline Science Requirements.
