  • Atmospheric extinction at Devasthal, Naini Tal 
    Mohan, V; Uddin, W; Sagar, R; Gupta, S. K (Astronomical Society of India, 1999)
    The atmospheric extinction coefficients in Johnson U, B, V, R and I photometric passbands are determined for the first time at Devasthal, Naini Tal during 1998 and 1999. A solid state stellar photometer mounted on a 52-cm ...
  • Atmospheric Extinction at Kavalur Observatory during 1980-85 
    Shylaja, B. S; Bhattacharyya, J. C (Indian Institute of Astrophysics, Bangalore, 1986)
    From a series of photoelectric scanner observations during 1980-85, the atmospheric extinction at Kavalur has been analysed. The variation of this appears to follow lamda/sup-4/ law. There is a general increase in the ...
  • Sky transparency over Naini Tal : A retrospective study 
    Kumar, B; Sagar, R; Rautela, B. S; Srivastava, J. B; Srivastava, R. K (Astronomical Society of India, 2000)
    We present an analysis of the atmospheric extinction coefficients measured during 1964 to 1999 in broad-band photometric passbands at U.P. State Observatory, Naini Tal. The extinction properties are also studied from the ...
  • Study of sky condition at Raipur and calibration of the photometer-telescope system 
    Padmakar; Barway, Sudhanshu; Pandey, S. K (Astronomical Society of India, 2000)
    To investigate local sky condition for valuable astronomical observation, we obtained values of atmospheric extinction coefficients in BVR filters for over 150 nights during the period of 1994 to 1997. Our observation over ...
