	abstract = {<p>Traveling Ionospheric Disturbances are quasi-periodic variations in the plasma that exist in the upper atmosphere and they impact the propagation of radio waves. Medium Scale Traveling Ionospheric Disturbances (MSTIDs) are defined as TIDs which travel at 100-250 m/s and have periods within the 1 hour range. Previously, most of the existing research has focused on MSTIDs in the Northern Hemisphere. This project seeks to determine whether there is enough data available to recognize seasonal trends in MSTID occurrence in the Southern Hemisphere. Currently, we have found some success in applying the PyDarnMusic algorithm to identify periods of high and low MSTID activity in the southern hemisphere in SuperDARN and have had success in replicating an existing study on the Falkland Islands radar. Going forward, we hope to refine the techniques which were originally used to identify MSTIDs in the Northern Hemisphere for use on the Southern Hemisphere in order to gain a better understanding of their climatology.</p>

	abstract = {<p>We model lunar dust particles as interacting ellipsoidal dipoles by means of Lennard-Jones potentials (L-J). Lunar surface dust particles are continuously bombarded by plasma charge particles coming from the solar wind. It has been recognized that solar wind bombardment leads to strong intergrain interactions between dust particulates leading to collective effects such as attraction of charged dust particles. Formation of electrostatically ordered dust structures is believed to be due to strong attractive van der Waals-like potentials at distances in the order of interparticle separation. Dust-dust electrostatic interactions and collisions may lead to particle coalescence or dust-lumps kept together due to Coulomb forces. On the other hand, dust ionization occurs after solar wind electrons collide with grains in the plasma sheath formed on the lunar surface. Particle coalescence and to an extent condensation is feasible when an attractive potential is present. Ellipsoidal dipole condensation is possible in the presence of a Lennard-Jones (L-J) potential.</p>
