Variations of signal strengths during solar bursts recorded at Kalyani corresponding to two different frequencies, 406.7 MHz and 100 MHz are reported.  The amplitude of the signals received at 406.7 MHz is found larger and that the flares analyzed are mostly of M-type. The signal strengths of the coronal effect at such times were very high compared to the surface effect of the Sun. The signal level of surface effect of the Sun at the peak activity varies in amplitude from 0.06 volts to 0.1 volt while those related to solar corona vary in between 7.0 to 7.2 volts. Both the solar wind velocity and proton density are found to increase in the dates of severe bursts and there are sudden disturbances in the arrival direction of solar wind particles. Also the geomagnetic indices are enhanced at the time of solar bursts when the DST index reduces rapidly.

Wikidata is emerging rapidly as an omnipresent information space. The main objective of Wikidata is to create a structure to represent all human knowledge in many different languages. It is a free, Linked Open Dataset (LOD) that can interact with humans and machines and act as a bridge between them. Wikidata serves as a central repository for structured data of all other Wiki-based applications (like Wikipedia, Wikibooks, and Wikinews), integrating them into a coherent unit. It is a multilingual, collaboratively editable central repository of structured and linked open data. Interestingly, Wikidata is based on a facet-based linked open data approach like, the theory of facet analysis proposed by Ranganathan. The literary works available in Wikidata are linked with the author of the work, the language of the work, and other important attributes like genre, publication year, and so on. The author of the work has properties like, date of birth, occupation, native language, writing language, and so on. These faceted linked data elements of literary works can be joined together based on the rule base of the Colon Classification (6th edition). The synthesis of the Colon class number is therefore amenable to automation in the Wikidata environment by using a set of suitable JavaScripts (these JavaScripts are called gadgets in the Wikidata environment). One such gadget is CCLitBox, developed by Stefano Bargioni (a librarian) and Carlo Bianchini (a teacher in LIS). This research study explores the applications of CCLitBox in generating CC 6th edition-based class numbers for Indian literary works.

Sunspots are temporary phenomena on the photosphere of the Sun which appear visibly as dark spots compared to surrounding regions. Sunspot populations usually rise fast but fall more slowly when observed for any particular solar cycle. The sunspot numbers for the current cycle 24 and the previous three cycles have been plotted for duration of first four years for each of them. It appears that the value of peak sunspot number for solar cycle 24 is smaller than the three preceding cycles. When regression analysis is made it exhibits a trend of slow rising phase of the cycle 24 compared to previous three cycles. Our analysis further shows that cycle 24 is approaching to a longer-period but with smaller occurrences of sunspot number.
