Description
Broad band B V R I, CCD photometry and spectrophotometry observations are presented for the blazar OJ 287. A nightly monitoring was carried out at San Pedro Martir and Beijing Observatories for five nights during minimum brightness of OJ287 (January 1998). The observations are nearly simultaneous (actually sequential due to day/night difference) and the spectral range covers approximately the same range as the broad band photometry. We report both continuum and line variability, and discuss our results.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    HARMONI at ELT: HIPOTEC electronics and control system
    HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 470nm to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 mas to 4 mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The
