At 16:00 PST On March 3 the deepest Ultraviolet exposure over the largest field was taken. The galaxy below, UGC 6151, is in the center of the field. It is a Low Surface Brightness Galaxy which we hope has lots of UV emission. This galaxy will also self-calibrate the field in case we serendipitiously detect other faint, diffuse galaxies over the near one square degree which is being imaged.
The pointing excursion problems that plagued much of the day 2 target acquisition and observations have been mostly corrected. HUT made some preliminary and successful observations of distant Quasars. In addition, the active galaxies NGC 4151 and NGC 1068 were done. WUPPE made successful observations of reflection nebulae associated with NGC 7023
A major goal of the HUT campaign is to get good data on QSO 1700+64 the most distant object in the Universe. An 1800 second exposure was done and the QSO was detected. Additional observations may then provide enough signal to noise to detected helium ionization edges in the spectrum which would indicate the presence of intergalactic helium at this redshift (z ~5). This would be a verification of a fundamental prediction of Big Bang Cosmology.
HUT obtained additional spectra of NGC 4151 and QSO 1700+64. A 1300 second exposure of MKN 279 was also done as were some other quasars. Markarian 279 is an interacting galaxy with a notable UV excess.
WUPPE obtained additional data on several hot stars located behind regions of dust in our Interstellar Medium. Stars observed were HD50138, HD10516 and HD197770.
WUPPE started off the day with another exposure on NG C 7023 . The rest of this day belong to HUT and UIT.
The UIT block begin with the first of a few exposures of SA 57, one of the most studied deep fields in the sky. A very good set of exposures through the A1,B1 and B5 filters were acquired of NGC 3351 . UIT finished the day with exposures of NGCs 5253, 2808, 3115, 1549, 4038, and 1672. Details of these objects can be found here .
UIT got a good image of the Milky Way satellite galaxy Sextans-A and other cool galaxies. This can be seen by going to the UIT update page .
WUPPE acquired a very long exposure of HD62542 and a shorter exposure of HD96548.
HUT observed the bright elliptical M49 and the star U-Gem. Later in the day HUT made observations of Jupiter, the interacting galaxy pair NGC 6090 and the UV bright galaxy- Markarian 3. Two additional QSOs were also observed.
HUT made additional exposures of the distant qso 1700+64 and the Cygnus Loop. Another QSO was also observed and a very long exposure (> 3000 seconds) was obtained of AM-HER.
HUT acquired additional spectra of NGC 4151, a new spectra of NGC 4631, more data on the Cygnus Loop and a new spectra of MKN 421. HUT ended the day with an exposure of the active galaxy NGC 3516
WUPPE acquired additional observations of NGC 7023 and data on NCEN-95.
WUPPE observed the stars HD216658 and HD161961 and HD 216898.
WUPPE acquired data on Mars
WUPPE acquired data on several stars in the SK association as well as the star AB-AUR
HUT began the day with a spectra of the active galaxy NGC 5548 and then later did a field in the Large Magellanic Cloud . Additional targets were NGC346, NGC1360, M60 again and a couple of more quasars.
WUPPE acquired data on Nova-Aql, NGC3132, HD 5980 and more SK stars.
HUT began the day by acquiring another spectra of 3C273 one of the most nearby quasars. These observations should help to determine if there is more absorption along the line of sight to 3C273 than has already been seen by HST. Additional spectra of NGC 4151 were acquired. HUT also got a spectrum of the VELA pulsar remnant and finished the day with Markarian 66.
WUPPE acquired data on the stars HD188220, SK69-239 and HR4049.
WUPPE started things off with HD188220 and later got data on the nebulae OMI-SCO and VELA-X1.
HUT got data on Markian 509, the peculiar star AG-DRA and 3 more quasars.
