“…Our survey partially overlaps with Lick's field RR I [MWF 361A; (J2000.0) = 16 h 27D25, (J2000.0) = À3 43A5]. Kinman et al (1984) list 10 RRLSs in the region of overlap that are fainter than the saturation limit of our observations. We recovered successfully seven of these stars (five RRab and two RRc stars), and our periods agree with the Lick survey to within 3 Â 10 À5 days.…”

With the 1 m Schmidt telescope of the Llano del Hato Observatory and the QUEST CCD camera, 380 deg 2 of the sky have been surveyed for RR Lyrae variables in a band 2 .3 wide in declination (centered at = À1) and covering right ascensions from 4C1 to 6C1 and from 8C0 to 17C0. The bright limit (due to CCD saturation) and the faint limit are V $13.5 and $19.7, respectively, which correspond to $4 and $60 kpc from the Sun. We present a catalog of the positions, amplitudes, mean magnitudes, periods, and light curves of the 498 RR Lyrae variables that have been identified in this region of the sky. The majority of these stars (86%) are new discoveries. The completeness of the survey has been estimated from simulations that model the periods and light curves of real RR Lyrae variables and take into account the pattern of epochs of observation. While the completeness of the survey varies with apparent magnitude and with position, almost everywhere in the surveyed region it is quite high (>80%) for the type ab RR Lyrae variables and between 30% and 90% for the lowamplitude type c variables.

“…Only 15 of the stars in Table 2 are listed in the GCVS, seven of which are from the Lick survey of RRLSs (Kinman et al , 1984 and will be discussed below. Of the remaining eight stars, only one, HN Vir, does not have a period in the GCVS.…”

“…The RR Lyrae star VIII-14 (Suntzeff et al 1991) was originally discovered in a survey with the Lick Astrograph (Kinman et al 1984); the star is in field VIII 1 , and has coordinates 17 h 07 m 33. s 93 +58 . The exposures on the latter plates are longer, and the magnitudes derived from them should be more accurate.…”

We show that SDSS J170733.93+585059.7 (hereafter SDSS J1707+58), previously identified by Aoki and collaborators as a carbon-enhanced metal-poor star (with s-process-element enhancements; CEMP-s), on the assumption that it is a main-sequence turn-off star, is the RR Lyrae star VIII-14 identified by the Lick Astrograph Survey. Revised abundances for SDSS J1707+58 are [Fe/H] = -2.92, [C/Fe] = +2.79, and [Ba/Fe] = +2.83. It is thus one of the most metalpoor RR Lyrae stars known, and has more extreme [C/Fe] and [Ba/Fe] than the only other RR Lyrae star known to have a CEMP-s spectrum (TY Gru). Both stars are Oosterhoff II stars with prograde kinematics, in contrast to stars with [C/Fe]< +0.7, such as KP Cyg and UY CrB, which are disk stars. Twelve other RR Lyrae stars with [C/Fe] ≥ +0.7 are presented as CEMP candidates for further study.

(33.155.068) investigated a field near NGC 7006 using RGU photometry and determined density functions for both populations. The Basel halo program also includes several papers by Fenkart and collaborators (33.113.027, 34. 113.036, and Astron. Astrophys. (in preparation)). Staller et al. (31.155.003) found a large number of red objects near the South galactic pole and discussed the M-dwarf distribution. Trefzger et al. (1984) used Walraven photometry to show a metallicity gradient for stars in SA 141 at the South galactic pole. The density function of faint stars towards the North galactic pole was derived by Yoshii (32. 155.034). Early-type stars near IC 4665 were investigated by Paparo and Balazs (33. 155.124). Kron, Cudworth, and Rybski (Yerkes) are beginning a programme of photometry, spectroscopy and proper motions for complete samples of faint stars in about twenty fields at intermediate latitudes. Tobin (37.113.034, 1984) has continued the studies by Tobin and Kaufmann (37.114.030) of high and intermediate-latitude B stars; uvbyg photometry shows that some of these are more than 500 pc from the galactic plane.The globular cluster system was studied by Frenk and White (31.155.001), who concluded that the sun's distance to the galactic centre is R 0 = 6,8±0.8 kpc. B. RADIO STUDIESSeveral regional surveys of southern HI made with the Argentine 100-m telescope were published (30.155.031). HI and other data were used by Dolidze (30.155. 044) to study the local distribution of gas and star forming regions. The Perseus arm region was the subject of an analogous study by Gerasimenko (34.155.139). Vallee (34.155.005) used rotation measure data from extragalactic sources in the direction of the Perseus arm to determine the magnetic field structure there and to constrain gravitational collapse theories of magnetic compression. HI in the direction of the Puppis window was surveyed by Stacy and Jackson (32.131.277) and used to study the turbulent characteristics of the interstellar medium. HI related to Gould's Belt was studied by Poppel and Olano (32.155.024, 33.155.030). Salter (34. 131.014) reviewed radio and other observations pertaining tc Loop I, the North Polar Spur, and considered the influence which this structure might have on the local medium.Several regional studies were carried out in the radio continuum. Kononov and Pyatunina (34.155.017) surveyed the galactic plane in the region of Mononceros at X7.6 cm. The extended component of the radio continuum at 408, 820, and 1420 MHz from the Cassiopeia-Perseus region was analyzed by Kallas et al. (34.155.069). Kanbach (34.155.020) reviewed the nonthermal radio emission from the local (< 2 kpc) region of the Galaxy and separated the emissivity into thin-and thick-disk components .Shell-like structures in the interstellar medium received much attention during the triennium. Hu (30.155.006) searched for HI shells at |b| > 10 , using filtering in velocity to enhance the shell features; she found correlations of the HI shells with radio continuum loops. Gosa...
