Re:     Announcement concerning coordinated observing proposals
        between RXTE and EUVE or ASCA and EUVE submitted to NASA.

	The Extreme Ultraviolet Explorer (EUVE) satellite project is
pleased to announce that it will accept the decision of the RXTE and
(US) ASCA Peer Review panels in granting time for coordinated
observations with EUVE. A successful proposal to either the RXTE or
ASCA panel would not have to be re-submitted to an EUVE Peer Review to
obtain EUVE observing time.  The EUVE project believes this
science-oriented, streamlined process will ease the burden on the
organizers of multi-wavelength campaigns and enhance the science
return of the satellites.

	Proposers who wish to take advantage of this opportunity must
make their case for EUVE observations in the Scientific Justification
section of their proposal(s). The EUVE project will conduct a
technical review to check the feasibility of the observation, and this
information will be reported to the RXTE and ASCA Peer Review
committees.  Therefore, it is in the proposer's best interest to
provide enough detail on expected EUV flux, assumed hydrogen column,
requested exposure and required signal-to-noise ratio for a valid
technical assessment.  This offer is meant to facilitate truly
coordinated campaigns.  Only enough EUVE exposure time will be awarded
to accomplish the goals of the coordinated observation, and not for
independent EUVE science.

	To minimize paperwork, the EUVE project will contact only
successful proposers for the detailed information needed (target
summary forms, P.I. contact address, etc) to plan their observation.
Information on the capabilities of EUVE can be found on the Internet
at www.cea.berkeley.edu or downloaded via anonymous FTP from
ftp.cea.berkeley.edu:/pub/nra96.

	No funding is associated with this opportunity.  There is
currently no reciprocity with RXTE or ASCA in this offer; in other
words, proposals for coordinated observations to future EUVE NRAs will
not be automatically granted time on RXTE or ASCA.  The proprietary
period for EUVE data is 6 months from the date of data delivery to the
P.I.  Standard Guest Observer support for data delivery and analysis
will be granted.  The Center for EUV Astrophysics, U.C. Berkeley, also
offers Guest Scientist computer accounts to aid in data analysis and
reduction.

	Questions regarding this opportunity and/or the EUVE satellite
can be emailed to : egoinfo@cea.berkeley.edu. Questions about the
capabilities of RXTE and ASCA satellites should be addressed to
xtehelp@athena.gsfc.nasa.gov and ascahelp@athena.gsfc.nasa.gov
respectively.
