mips!swrinde!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@apple.com (Ron Baalke) Subject: AXAF Contract (Forwarded) Paula Cleggett-Haleim Headquarters, Washington, D.C. March 21, 1991 (Phone: 202/453-1547) RELEASE: 91-46 SMITHSONIAN ASTROPHYSICAL OBSERVATORY WINS AXAF CONTRACT NASA's Marshall Space Flight Center, Huntsville, Ala., has selected the Smithsonian Astrophysical Observatory, Cambridge, Mass., for negotiations leading to award of a contract to design, develop and operate a science support center for the space-based Advanced X-ray Astrophysics Facility (AXAF). Scheduled for launch in 1998, AXAF will be the third in NASA's series of Earth-orbiting Great Observatories. The primary role of the science center will be to provide a service to the international scientific community by developing and overseeing an observation program for the X-ray telescope and by managing reception and distribution of the data it collects. In addition, the facility will provide support during development of the X-ray telescope and its complement of sensitive instruments, for testing and verification of ground support systems, for calibration of the instruments and for those orbital operations that relate to the science instrument data. The science center will serve as the primary focal point for the observer community using the X-ray telescope. Services it will provide for users or potential users will include: o Assistance in the preparation of observing proposals; o Support for scientific observations, including planning the best observing strategy for study of specific objects; o Processing and distribution of scientific data; and, o Offering users appropriate software and computer resources, so they can most effectively and efficiently use the data. The cost-reimbursement for the AXAF Science Center is at a proposed cost of $86.7 million. The contract is for a 10-year period of performance, spanning the design, development and testing of the telescope as well as support to its launch and early years of science mission operations. A major readiness milestone for the AXAF Science Center will be to provide support for ground-based calibration tests in 1995. The center must be fully operational to support the telescope's launch in 1998. Location of the facility is to be determined by the Smithsonian Astrophysical Observatory as part of this effort. The Marshall center, which manages the AXAF program for NASA, will manage the contract. The AXAF program is under the direction of NASA's Office of Space Science and Applications, Washington, D.C. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | Change is constant. /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | |_____|/ |_|/ |_____|/ | ------------------------------ Date: Fri, 22 Mar 91 12:58:00 MST From: oler%HG.ULeth.CA@BITNET.CC.CMU.EDU (CARY OLER) Subject: MAJOR SOLAR FLARE ALERT - 22 MARCH - STRANGE TYPE IV WITH 21 MARCH EVENT X-St-Vmsmail-To: st%"space+@andrew.cmu.edu" -- MAJOR SOLAR FLARE ALERT -- MARCH 22, 1991 Flare Event Summary Potential Impact Assessment -------- MAJOR ENERGETIC EVENT SUMMARY Another major flare erupted from Region 6555 at a location of S25E35. This event began at 08:33 UT, peaked at 08:40 UT and ended at 09:19 UT on 22 March. There was a tenflare with this event, rated at 870 s.f.u.. Also, a 245 MHz burst was observed at an intensity of 12,000 s.f.u. No sweeps were observed. The flare was fairly impulsive and had a low integrated x-ray flux. The event attained a class M6.3/1B rating. POTENTIAL TERRESTRIAL IMPACT ASSESSMENT No terrestrial impacts are expected with this latest major flare. It had some moderately strong radio emissions but was not associated with any sweeps and was an impulsive event. The most strange event which is really turning heads is the major class 5.4/2B flare of 21 March (at 23:44 UT). This event was not particularly unusual as far as the flare itself goes, but the radio emissions observed were very odd indeed. The flare was associated with a strong Type IV emission which drifted from low to high frequencies (it should have been the other way around). The emission increased in intensity with time and reached very brilliant levels. The event is STILL IN PROGRESS at the time of this writing. It has been categorized a continuum Type IV emission. It is perhaps one of the strangest emissions observed in seven years. Something is vigorously exciting the electrons over that region, but no one knows what it might be. The flare itself was not extraordinary. In fact, it was rather "average". There is a possibility that a Type II could have occurred with the 23:44 UT flare of 21 March. There is uncertainty regarding this due to the fact that the Type IV drifted from low to high frequencies and may have "swallowed" the Type II emission. So it is certainly possible that a Type II could have occurred with this event (it would normally be observed with a Type IV continuum emission as intense as this one has been). This event is very difficult to assess as far as potential terrestrial impacts are concerned. The flare itself was impulsive and of rather low intensity. But the wierd long duration Type IV continuum emission together with the possible occurrence of a Type II is raising questions. We currently believe that a low to moderate risk exists for increased terrestrial activity late on 23 March or on 24 March. There is a slightly higher probability that no terrestrial impacts will occur, but these predictions are not associated with high confidence levels. A Potential Geomagnetic Storm Warning may be issued on 23 March just to cover the "bases." Analysis of this odd event will continue. Major flaring is expected to continue from Region 6555. Terrestrial impacts from very energetic flaring could be high. Watch for future alerts and possible warnings. ** End of Alert ** ------------------------------ End of SPACE Digest V13 #318 *******************
