Determination of horizontal velocity fields at the sun’s surface with high spatial and temporal resolution
We analyse the two algorithms which have been used in the past few years to determine the horizontal flow fields at the Sun’s surface, namely the Local Correlation Tracking (LCT) of L. November and the Feature Tracking of L. Strous. Analysing the systematic errors introduced by LCT, we show that these errors come from the averaging processes. More precisely, they arise from the interpolating st...
متن کاملFlow patterns around old sunspots and flare activity
Newmagnetic flux emerges significantly more probably in already existing solar active regions. Based on the the Debrecen Observatory photographic observations, several active regions are collected, where at least one large, X-class flare was recorded, and emergence of new activity, birth and quick motion of new umbrae was observed in the vicinity of old spots, the new activity emerged in the ce...
متن کاملVelocity-map imaging at low extraction fields.
We present a velocity-map imaging (VMI) setup for photoelectron imaging that utilizes low electric extraction fields. This avoids any complications that could arise from electrostatic interactions between the extraction field and the molecular properties that are probed and has a minimal effect on the trajectory of ions in ion beam experiments. By using an attractive potential supplied to the d...
متن کاملMinimum-Time Roll Around the Velocity-Vector Maneuver of Aircraft
In this paper, some results are provided for minimum time roll about velocity vector maneuvering with thrust-vectoring and aerodynamic control in effect. The mathematical model for attitude motions of the aircraft is developed. First order necessary conditions for optimality using Pontryagen principle is applied, and the existence of an extreme family of solutions for the maneuver is shown. Mul...
متن کاملEvershed Clouds as Precursors of Moving Magnetic Features around Sunspots
The relation between the Evershed flow and moving magnetic features (MMFs) is studied using highcadence, simultaneous spectropolarimetric measurements of a sunspot in visible (630.2 nm) and near-infrared (1565 nm) lines. Doppler velocities, magnetograms, and total linear polarization maps are calculated from the observed Stokes profiles. We follow the temporal evolution of two Evershed clouds t...
