Periodicities in solar coronal mass ejections [PDF]
Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the most recent solar maximum cycle 23 are reported here for the first time using the four-year data (February 5, 1999 to February 10, 2003) of the Large Angle Spectrometric ...

Integration of solar flare and coronal mass ejection event dataHarvard Dataverse [PDF]
Solar flares and coronal mass ejections are solar transient events that can impact our technological infrastructure in near-Earth and Earth environments. While related, not all flares generate CMEs and there are a limited number of resources that connect

Solar Activity and Coronal Mass Ejections: Teacher's Guide [PDF]
In this activity, students investigate solar activity and discover that the Sun constantly emits matter into space in the form of the solar wind. They will also find that from time to time the sun also ejects clouds of charged particles in an event ...

Coronal dimmings associated with coronal mass ejections on the solar limb [PDF]
<p>We studied&#160;43 coronal dimming events associated with Earth-directed&#160;coronal mass ejections (CMEs)&#160;that were&#160;observed in quasi-quadrature by&#160;the SDO and STEREO satellites.&#160;We derived the properties of the dimmings as observed above&#160;the limb by ...

Solar Coronal Mass Ejections [PDF]
In addition to the more or less steady solar wind, the Sun also ejects mass in highly time dependent events taking place in the corona once every few days at solar activity minimum and as often as three times a day at solar activity maximum (Hundhausen 1988, Low 1986).

Review of Fast Solar Jets and Coronal Mass Ejections [PDF]
The Sun is a magnetically active star. It has a powerful magnetic field that shifts slightly from year to year until it reverses about every eleven years. The sun's magnetic field has many effects, the collection of which is called solar activity such as,

Interaction of coronal mass ejections and the solar wind
Aims.Our goal is to thoroughly analyse the dynamics of single and multiple solar eruptions, as well as a stealth ejecta. The data were obtained through self-consistent numerical simulations performed in a previous study. We also assess the effect of a different background solar wind on the propagation of these ejecta to Earth.Methods.We calculated all ...

What Do Halo CMEs Tell Us about Solar Cycle 25?
It is known that the weak state of the heliosphere due to diminished solar activity in cycle 24 backreacted on coronal mass ejections (CMEs) to make them appear wider for a given speed. One of the consequences of the weak state of the heliosphere is that
