Abstrak :
Pelontaran massa korona (CME) adalah salah satu aktivitas matahari yang
menghasilkan pancaran partikel energi tinggi ke angkasa. Partikel-partikel ini kemudian menjadi angin surya yang selanjutnya bisa mencapai bumi. Telaah ini mencoba melakukan analisis pada beberapa peristiwa CME yang cukup besar untuk bisa mendapatkan informasi mengenai pengaruh yang mungkin bisa diberikannya pada daerah-daerah yang cukup jauh melalui pancaran angin surya yang dihasilkannya. Untuk itu diamati juga gejala-gejala angin surya yang kemungkinan diakibatkan oleh CME tersebut. Didapat bahwa beberapa peristiwa CME menghasilkan angin surya yang cukup deras, tetapi ada juga yang tidak menghasilkan angin surya yang cukup deras. Perbedaan ini masih perlu ditelaah lebih lanjut dalam rangka mendapatkan gambaran yang lengkap mengenai adanya perbedaan-perbedaan tersebut.

Abstrak :
In this paper we present the relationship between long duration H-alpha flare events and suspot number during the period of 1980-2004. We counted as long duration events all those of one hour or more. It is shown that the long duration H-alpha flare events tend to trace the sunspot cycle with some anomalies

Abstrak :
Flare observations are numerous, and this approach should be supported by theoretical approach especially through modelling by numerical simulation. We make an analysis of reconnection process which precedes flare through numerical simulation. This method is the best method in flare modelling because processes in flare behave non lineraly so analytical method can't be used.

Abstrak :
Three Long Duration Event (LDE) flares erupted from solar surface in the period of 15-17 January 2005. They have similar characteristics, which are gradual flares and reach maximum intensity longer than their decay. These LDE flares were accompanied by CME and proton event which led to the increase of 10.7 cm flux and to the local geomagnetic storms at middle and high latitude.

Abstrak :
This book is revised and extended to include using a low-cost "go-to" telescope, there are various pitfalls to be avoided, and how this class of instrument can make amateur astronomy more accessible to those with limited time at their disposal. It also discusses the new breed of mid-range digital cameras that include powerful on-board processing and image enhancement software that used to be available only to people with advanced astronomical CCD cameras. Finally, there are detailed reviews and test reports on some of the budget telescopes that are available on main street and by mail order.

Abstrak :
This book explores the subject in the context of quantum gravity. A novel approach to uncover the dark faces of the standard model of cosmology. The possibility that dark energy and dark matter are manifestations of the inhomogeneous geometry of our universe. On the history of cosmological model building and the general architecture of cosmological modes. Illustrations on the large scale structure of the universe. A new perspective on the classical static Einstein cosmos. Global properties of world models including their topology. The arrow of time in a universe with a positive cosmological constant. Exploring the consequences of a fundamental cosmological constant for our universe. Exploring why the current observed acceleration of the universe may not be its final destiny. Demonstrating that nature forbids the existence of a pure cosmological constant. Our current understanding of the long term (in time scales that greatly exceed the current age of the universe) future of the universe. And the long term fate and eventual destruction of the astrophysical objects that populate the universe, including clusters, galaxies, stars, planets, and black holes.
