Abstract

The partial solar eclipse was observed during the eclipse event on 9 March 2016. Research was focused on mainly the intensity decreasing and increasing during contact of Moon-disk with Solar-disk. During first contact decreasing in intensity is in focused. After minimum intensity phase we further continue to inspect the intensity increasing. We posed that the intensity profile has some degree of asymmetry during complete solar eclipse process.

Abstract

On early morning on 11 March 2015 a solar exceptionally energy release was calculated by MHDoobservational parameters and showed there would be energy liberated by the Sun. Later we observed on 17 March 2015, we did notice geomagnetic large deviation. As preliminary conclusion we supposed that on 11 March 2015 the Sun did release huge energy into interplanetary space.

Abstract

By assuming the Sun in quiet condition we derived coronal thermal structure for low solar coronal magneto- plasma atmosphere. Ideal gas law in a static equilibrium configuration in coronal magnetic plasma state isderived and the solution may be directed to figure-out the thermal structure in mixed plasma and magneticfields within the low corona. The results show that corona may have hot and ‘cool’ solution in low coronaunder the condition when the Sun in quiet condition.

Abstract

An analytical solution of initial and un-sheared low solar coronal magnetic arcade as initial value isperturbed and equilibrium is assumed to loss. The dynamical state of lossing equilibrium is descibed first andpossible consequnces to the numerical scheme is derived. The dynamical evolution is followed by computersimulation which computed numerical solutions of complete set time-dependent magnetohydrodynamicspartial differential equations. Automatic algorithm to inspect the MHD fast-mode speed is introduced tomaintain simulation scheme stable during computations. Results show there will be shocks, known as MHD- waves shock, along the way to interplanetary space. Temperature shock is not prominent and only arelatively unsignificant temperature rise is resulted, instead density shock is noticeable. The density rise isrelatively far greater to order of kg 9 1.010 .

Abstract

Sinar Matahari yang sampai di permukaan planet Mars digunakan sebagai sarana untuk mendapatkan data eksitasi molekulmolekul di atmosfer planet Mars. Pengamatan dilakukan pada malam hari saat atmosfer Bumi tenang, tidak tereksitasi olehsinar Matahari. Hasil pengamatan diharapkan dapat digunakan untuk memperoleh informasi global atmosfer planet Mars dandigunakan untuk perbandingan dengan spectrum molekul planet Bumi.

Abstract

Two dimensional magnetic-structures is developed and derived in the basic assumption line-tied condition in solar plasma. The type is two-dimensional half-circle magnetic arcade topology imbedded in photosphere dense plasma. The magnetic topology is assumed to be converted dynamically due to disturbance in magnetic fields and became a CME. Disturbance is derived from magneto-hydrostatic condition and perturbation is applied as first-order small deviation along the magnetic fields. Along the base of the magnetic arcade every disturbance is assumed to be zeroed by dense plasma and the magnetic fields of line is line-tied on photosphere. By inspecting snapshot data it is found that the derived structure is similar with solar coronal magnetic structure prior a launch of CME from coronagraph white light data.
