BVI CCD surface photometry of the globular cluster NGC 2419
The radial surface luminosity distribution of the Globular Cluster NGC2419 in the B, V, and I photometric bands is presented. Data are derivedby single frame CCD images of (25 x 17) sq arcmin. The simplemethodology used to obtain measurements actually related to the diffuseemission of the globular cluster without contamination due to brightstars, field stars or other kinds of singularities is described. Surfacebrightness is compared to the theoretical one proposed by King (1965)for homogeneous self-gravitating systems. Data extending to half thetidal radius show good agreement with the model. The present core radius(Rc = 0.34 +/- 0.01 arcmin) returns less than that calculated byPeterson and King (1975) with data of Kron and Mayall (1960): Rc = 0.42arcmin.

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.
