Low resolution spectroscopy of a binary system containing a millisecond pulsar over its orbital period. The only OB supplied lasts for two hours, but this has to be accepted as the observations should be continuous for this period. Low airmass required to minimize changes in telluric features during the execution of the observation. Original seeing constraint of 0"6 rather strong for a B-class program, even more so taking into account that it has to be maintained for two whole hours. User thus increased it to 0"9. User supplies a visible finding chart, and has no infrared chart. Beware of the probably very different appearance of the field, of low galactic latitude, in the infrared. Flat field and wavelength calibration attached at the end of the template. Not clear that is really needed, but anyway user is willing to pay time for it. Acquisition on the slit relies on the two stars marked as "A" and "B" on the finding chart by the click-on-two-stars procedure; no position angle is predefined. Coupled with the wavelength of the finding chart pointed out before, acquisition may be difficult. Part C of this program is a follow-up based on the outcome of the execution of the present part B.
