EUVE OBSERVES FIRST CALIBRATION TARGETS

The EUVE Observatory has started to observe its first calibration
targets.  Last  night  the hot white dwarf 1254 +223 was observed
and was detected strongly in the scanner A, B  and  C  detectors.
The source was detected in the longest wavelength survey detector
(Tin).

The hot white dwarf 1620 -391 was used to calibrate the deep sur-
vey and spectrometer detectors.

EUVE OBSERVATORY SEES FIRST LIGHT

The seven detectors of the EUVE Observatory were turned  on  suc-
cessfully  on Sunday, June 21, and obtained their first images of
the EUV sky. All detectors are operating  well,  with  the  back-
ground  in  all  detectors  counting at low count rates. The geo-
coronal 304 A and interplanetary 584 A glow were detected at nom-
inal count rates in the spectrometer. The first in-orbit calibra-
tions began on Monday, June 22.

The deadline for Guest Observer proposals is July 1  -  get  your
proposals in!! EUVE is operational.

EUVE CALIBRATION TARGETS MODIFIED DUE TO LAUNCH SLIPS

The EUVE Instrument Scientist Pat Jelinsky reports  that  due  to
the  EUVE  launch slip, there were small adjustments to the cali-
bration targets for EUVE.

Here are the spectrometer targets that cannot be observed because
of the launch slip:
        GJ 644A
        Sco X-1

Here are the spectrometer targets that were added because of  the
launch slip:
        AT Mic
        PKS 2155-304

All  of  these   targets   are   listed   in   the   "EUVE   Deep
Survey/Spectrometer Calibration Target List (April 16, 1992)."
