|Abstract||The 1.2-m Schmidt telescope at IIalcakala found a comet on November 6, 2002 during the Near Earth Asteroid Tracking (NEAT)and it was reported by S.II.Pravdo. At the time of discovery its magnitude was around 17.3. Several recorded positions of the comet enabled B. G. Marsden to establish the perihelion date as February 18.30, the perihelion distance as 0.099 AC and the orbital period as about 37 years for the comet. Visual magnitude estimates reported during December by several observers were inconsistent. The total visual magnitude was between 8.0 and 8.5 around December 29. The comet brightened in January. The magnitudes ranging from 6.8 to 7.5 and coma diameter estimates ranging from 5 to 12 aremin around January 14 were reported. CCD images on January 17 revealed an apparent tail disconnection event. The comet's rate of brightening slowed around February 3, as observers were reporting brightness estimates below the predicted values.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDL India) pilot project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDL India is designed to hold content of any language and provides interface support for leading Indian languages. It is being arranged to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular form of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examination, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. The pilot project is devising a framework that is being scaled up with respect to content volume and diversity to serve all levels and disciplines of learners. It is being developed at Indian Institute of Technology Kharagpur.
NDL India is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with respective organization from where the contents are sourced and NDL India has no responsibility or liability for these. Every effort is made to keep the NDL India portal up and running smoothly. However, NDL India takes no responsibility for, and will not be liable for, the portal being unavailable due to technical issues or otherwise.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDL India) pilot project.
