The processed images reveal radial structure with high density contrast at all observable scales down to the optical limit of the instrument, giving the corona a “woodgrain” appearance. Inferred density varies by an order of magnitude on spatial scales of 50 Mm and follows an f −1 spatial spectrum. The variations belie the notion of a smooth outer corona. They are inconsistent with a well-defined “Alfvén surface,” indicating instead a more nuanced “Alfvén zone”—a broad trans-Alfvénic region rather than a simple boundary. Intermittent compact structures are also present at all observable scales, forming a size spectrum with the familiar “Sheeley blobs” at the large-scale end. -

Simpson Director, OSO Programs BALL BROTHERS RESEARCH CORPORATION SUBSIDIARY OF BALL CORPORATION BOULDER, COLORADO F72-01 PREFACE During the 1950's rapid progress was made in solar physics and in instrument and space hardware technology, using rocket and balloon flights that, although of brief duration, provided a view of the sun free from the obscuring atmosphere. The significance of data from these flights confirmed the often-asserted value of long-term observations from a spacecraft in advancing our knowledge of the sun's behavior. Thus, the first of NASA's space platforms designed for long-term observations of the universe from above the atmosphere was planned, and the Orbiting Solar Observatory program started in 1959. Solar physics data return began with the launch of OSO-1 in March of 1962. OSO-2 and OSO-3 were launched in 1965, OSO-4 and OS0-5 in 1967, OSO-6 in 1969, and the most recent, OSO-7/, was launched on September 29, 1971. All seven OSO's have been highly successful both in scientific data return and in per- formance of the engineering systems. -

Identification of Interplanetary Coronal Mass Ejection with Magnetic Cloud in Year 2005 at 1 AU
INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 3, ISSUE 6, JUNE 2014 ISSN 2277-8616 Identification Of Interplanetary Coronal Mass Ejection With Magnetic Cloud In Year 2005 At 1 AU D.S.Burud, R .S. Vhatkar, M. B. Mohite Abstract: Coronal mass ejection (CMEs) propagate in to the interplanetary medium are called as Interplanetary Coronal Mass Ejection (ICME). A set of signatures in plasma and magnetic field is used to identify the ICMEs. Magnetic Cloud (MC) is a special kind of ICMEs in which internal magnetic field configuration is similar like flux rope. We have used the data obtained from ACE Advance Composition Explorer (ACE) based in-situ measurements of Magnetic Field Experiment (MAG) and Solar Wind Electron, Proton and Alpha Monitor (SWEPAM) experiment for the data of magnetic field and plasma parameters respectively. The magnetic field data and plasma parameters of ICMEs used to distinguish them as magnetic cloud, non magnetic cloud. We analyzed eighteen ICMEs observed during January 2005 to December 2005, which is the beginning of declining phase of solar cycle 23. The analysis of magnetic field in the frames of the flux ropes like structure using a Minimum Variance Analysis (MVA) method, and have identified 30% ICMEs in the year 2005, which shows magnetic field rotation in a plane and confirmed as ICMEs with MCs. Keywords: magnetic cloud (MC), interplanetary coronal mass ejection (ICME), minimum variance analysis (MVA). ———————————————————— Introduction:- Table No: 1 Signatures used to identify ICMEs in the Coronal mass ejections (CMEs) are an energetic Heliosphere phenomenon originated in the Sun‘s corona, CMEs are eruptions of plasma and magnetic fields that drive space Sr.no. -

Abstract: In light of future missions beyond low Earth orbit (LEO) and the potential establishment of bases on the Moon and Mars, the effects of the deep space environment on biology need to be examined in order to develop protective countermeasures. Although many biological experiments have been performed in space since the 1960s, most have occurred in LEO and for only short periods of time. These LEO missions have studied many biological phenomena in a variety of model organisms, and have utilized a broad range of technologies. -
