ABSTRACT Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the mostrecent 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 SpectrometricCoronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO). Inparallel, mid-term quasi-periodicities in solar X-ray flares (class >M5.0) from theGeosynchronous Operational Environment Satellites (GOES) and in daily averages ofAp…

Coronal Mass Ejections over Solar Cycles 23 and 24

We present a statistical analysis of solar coronal mass ejections (CMEs) based on 23 years of quasi-continuous observations with the LASCO coronagraph, thus covering two complete Solar Cycles (23 and

Short-term periodicities in interplanetary, geomagnetic and solar phenomena during solar cycle 24

In this paper we study the quasi-periodic variations of sunspot area/number, 10.7 cm solar radio flux, Average Photospheric Magnetic Flux, interplanetary magnetic field (Bz) and the geomagnetic

Short-term periodicities in interplanetary, geomagnetic and solar phenomena during solar cycle 24

In this paper we study the quasi-periodic variations of sunspot area/number, 10.7 cm solar radio flux, Average Photospheric Magnetic Flux, interplanetary magnetic field (Bz) and the geomagnetic

Quasiperiodic Variations of Coronal Mass Ejections with Different Angular Widths

Coronal mass ejections (CMEs) are energetic expulsions of organized magnetic features from the Sun. The study of CME quasiperiodicity helps establish a possible relationship between CMEs, solar

Short-Period Fluctuations in Coronal Mass Ejection Activity during Solar Cycle 23

We have constructed a time series of the number of coronal mass ejections (CMEs) observed by SOHO/LASCO during solar cycle 23. Using spectral analysis techniques (the maximum entropy method and

Different Periodicities in the Sunspot Area and the Occurrence of Solar Flares and Coronal Mass Ejections in Solar Cycle 23 – 24

In order to investigate the relationship between magnetic-flux emergence, solar flares, and coronal mass ejections (CMEs), we study the periodicity in the time series of these quantities. It has been

Evolution and rotation of large-scale photospheric magnetic fields of the Sun during cycles 21–23 - Periodicities, north-south asymmetries and r-mode signatures

We present the results of an extensive time series analysis of longitudinally-averaged synoptic maps, recorded at the National Solar Observatory (NSO/Kitt Peak) from 1975 to 2003, and provide

The Near 160 Day Periodicity in the Photospheric Magnetic Flux

A periodicity near 154 days was discovered in the number of high-energy solar flares detected by Solar Maximum Mission (SMM) and Geosynchronous Operational Environmental Satellites (GOES) during the

The Gamma-Ray Spectrometer (GRS) aboard the Solar Maximum Mission (SMM) discovered a 154 day periodicity in solar flare rates. Subsequently, periodicities in various solar flare activities and in

A 154-day periodicity in the occurrence of hard solar flares?

Since the launch of the Solar Maximum Mission (SMM) satellite on 1980 February 14, the Gamma-Ray Spectrometer (GRS)1 has been monitoring the Sun in the energy range 0.3–100 MeV. Because of its large

Interplanetary magnetic field periodicity of ∼153 days

We report on the finding of a 153‐day periodicity in the magnetic field strength and solar wind speed measured at 1 AU during the years 1978–1982. The period and the occurence epoch are consistent

Coronal mass ejections, interplanetary ejecta and geomagnetic storms

Studies using SOHO spacecraft data have demonstrated that frontside halo coronal mass ejections (CMEs) detected by the LASCO coronagraphs generally precede geomagnetic storms. Nonetheless, about

The 154-day and related periodicities of solar activity as subharmonics of a fundamental period

IN 1984 a periodicity of 154 days was found in the record of solar flare activity1 from 1980 to 1983. Since then, the same periodicity has been found in many different measures of solar flare

Coronal mass ejections, magnetic flux ropes, and solar magnetism

This review on coronal mass ejections (CMEs) treats hydromagnetic issues posed by observations, in order to relate CMEs to flares and prominence eruptions and to consider the roles these processes

Confirmation of a 152 day periodicity in the occurrence of solar flares inferred from microwave data

Evidence for a periodicity about 155 +- 5 days in the production of energetic solar flares was reported in 1984 by Rieger et al. and Kiplinger et al. The data on which these analyses were based are

Long period oscillations in solar diameter measurements

Observations of the Sun with a Danjon-type visual astrolabe have been recorded since 1975 at the CERGA Observatory. The primary goal of these observations is to determine the orbital elements of the

Coronal Mass Ejections

Coronal mass ejections are seen as bright features that move outward through the solar corona at speeds from 10 to about 2,000 km s-1. They involve the expulsion of substantial quantities of plasma
