Northern JHK Standard Stars for Array Detectors
We report J, H, and K photometry of 86 stars in 40 fields in theNorthern Hemisphere. The fields are smaller than or comparable to a 4' x4' field of view and are roughly uniformly distributed over the sky,making them suitable for a homogeneous broadband calibration network fornear-infrared panoramic detectors. K magnitudes range from 8.5 to 14 andJ-K colors, from -0.2 to 1.2. The photometry is derived from a total of3899 reduced images; each star has been measured, on average, 26.0 timesper filter on 5.5 nights. Typical errors on the photometry are ~0.012mag.

MK classification and photometry of stars used for time and latitude observations at Mizusawa and Washington
MK spectral classifications are given for 591 stars which are used fortime and latitude observations at Mizusawa and Washington. Theclassifications in the MK system were made by slit spectrograms ofdispersion 73 A/mm at H-gamma which were taken with the 91 cm reflectorat the Okayama Astrophysical Observatory. Photometric observations in UBV were made with the 1-meter reflector at the Flagstaff Station of U.S.Naval Observatory. The spectrum of HD 139216 was found to show a strongabsorption line of H-beta. The following new Am stars were found:HD9550, 25271, 32784, 57245, 71494, and 219109. The following new Apstars were found: HD6116, 143806, 166894, 185171, and 209260. The threestars, HD80492, 116204, and 211376, were found to show the emission inCaII H and K lines.

UBV photometry of stars whose positions are accurately known. III
UBV photometric observations of 417 stars at BD declination 35-49 degfrom the NPZT(74) catalog of Yasuda et al. (1982) and the AGK3R catalogof Corben (1978), obtained with the 40-cm Cassegrain reflector atKvistaberg Observatory during 1984-1985, are reported. The data arepresented in tables, and the mean errors per observation are given as0.016 mag in V, 0.011 mag in B-V, 0.012 mag in U-B for U less than 10,and 0.026 mag in U-B for U greater than 10.
