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 Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO).

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

CORONAL MASS EJECTIONS AND SUNSPOTS—SOLAR CYCLE PERSPECTIVE [PDF]
Recent studies have indicated that the occurrence of the maxima of coronal mass ejection (CME) rate and sunspot number (SSN) were nearly two years apart. We find that the two-year lag of CME rate manifests only when the SSN index is considered and the lag is minimal (two-three months) when the sunspot area is considered.

Energetics of a Solar Flare and a Coronal Mass Ejection Generated by a Hot Channel Eruption [PDF]
Hot channels (HCs) are prevalent in the solar corona and play a critical role in driving flares and coronal mass ejections (CMEs). In this paper, we estimate the energy content of an X1.4 eruptive flare with a fast CME generated by an HC eruption on 2011

Coronal dimmings and what they tell us about solar and stellar coronal mass ejections [PDF]
Coronal dimmings associated with coronal mass ejections (CMEs) from the Sun have gained much attention since the late 1990s when they were first observed in high-cadence imagery of the SOHO/EIT and Yohkoh/SXT instruments.

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,

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 ...

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
