  • Solar observational programs and facilities at UPSO, Naini Tal 
    Gaur, V. P; Verma, V. K; Uddin, W (Astronomical Socity of India, 1998)
    We present here the overview of the solar facilities at the U.P. State Observatory, Naini Tal, which have been developed over years for the observations of solar activity phenomena. The various backend instruments and the ...
  • Study of Three Homologous Solar Flares Observed from Active Region NOAA 9033 on 12th June 2000 
    Verma, V. K; Vats, H. O (Astronomical Society of India, 2003)
    In the paper, we present a study of three homologous H flares observed on 12th June 2000 in active region (AR) NOAA 9033. During the observation of AR NOAA 9033 on 12th June 2000, we observed 1st solar flare between 0135-0155 ...
  • Surge activities on November 26-28, 1990 
    Uddin, W; Verma, V. K (Astronomical Society of India, 2000)
    We report here a study of 8 solar surges observed in H? emission on the west solar limb (active region NOAA 6368) on 26, 27 and 28 November 1990. Three surges were observed on 26 November of durations 35, 86 and 40 min at ...
  • Surge prominence of 1981 November 19 
    Verma, V. K; Pande, M. C (Astronomical Society of India, 1982-09)
    Time-lapse photographic observations with 0.7 Armstrong passband H-alpha filter and the morphological behaviour of the surge prominence recorded on 1981 Novermber 19 have been described. The surge was recorded both in the ...
  • Time delay between H-alpha and soft x-ray emissions during solar flares 
    Verma, V. K; Pande, M. C (Astronomical Society of India, 1985-06)
    A statistical analysis of time delays between H-alpha and soft x-ray (SXR) emissions at onset and peak respectively during solar flares is presented. We find that at the onset of flares SXR emission starts simultaneously ...
  • Total solar eclipse observations of 24 October 1995 from Meja Khas, Allahabad 
    Verma, V. K; Uddin, W; Gaur, V. P; Joshi, G. C; Bondal, K. R; Pant, P (Astronomical Society of India, 1996)
    Monochromatic coronal images during the total solar eclipse of 24 October 1995 were successfully obtained in 6374 Amstrong [Fe X]line. The experiment carried out a Meja Khas, Allahabad during the eclipse and the preliminary ...
  • Twisted surge of 1981 December 25 
    Verma, V. K (Astronomical Society of India, 1983-03)
    Photographic observations and the morphological behaviour of the surge prominence of importance class 1 recorded with the 0.7 A passband H-alpha filter on 1981 December 25 have been described. The surge was recorded both ...
