Abstract:

The SCINDA receiver has been operational at the Institute of Radio Physics and Electronics, University of Calcutta, Calcutta, India since November 2006. During the period July 2008 through July 2009, operation of the SCINDA receiver has been almost uninterrupted except during the total solar eclipse of July 22, 2009. A dedicated broadband internet connection is operational from the government-run Bharat Sanchar Nigam Limited BSNL since October 2008. An on-line UPS has been procured to prevent data loss due to disruption of power. Data from the SCINDA receiver is available to the Satellite Beacon Group of this Institute in the post-processed form. It has been utilized for studying some Space Weather events occurring on February 2, 2008 and September 25, 2008 when post-sunset scintillations were observed on GPS links from Calcutta 22.58 deg N, 88.38 deg E geographic magnetic dip 32 deg N. The SCINDA GPS S4 and elevation angle plot of September 25, 2008 showed fluctuations on the SV12 link around 2130 LT. The period of this report correspond to very low sunspot number resulting in very few severe Space Weather events as observed on February 02, 2008 and September 25, 2008. Although the current solar cycle has been weak so far, it may take only one powerful Space Weather event to cause serious damage to the technological infrastructure on which society relies. This SCINDA station in Kolkata India is operational continuously throughout the year supplying data to the network of such stations.
