A study of the kinematic and volumetric co-evolution of Earth-directed CMEs
Ashutosh Pattnaik, Nat Gopalswamy, Ranadeep Sarkar +3
While flare-associated CMEs generally show a strong association between flare X-ray flux and CME kinematics, their volumetric evolution and its link to both kinematics and flare ac…
A Wide-band High-frequency Type-II Solar Radio Burst
V. Vasanth, Yao Chen, G. Michalek
Type-II radio bursts are typically observed below ~ 400 MHz, with narrow-band slowly-drifting fundamental and harmonic structures. Here we report an unusual high-frequency wide-ban…
Implications of the abundance of halo coronal mass ejections for the strength of solar cycle 25
Nat Gopalswamy, Grzegorz Michalek, Seiji Yashiro +3
We assess the relative strength of solar cycle (SC) 25 with respect to SCs 23 and 24 based on the abundance of halo coronal mass ejections (CMEs). We make use of the halo CME datab…
The SOHO LASCO CME Catalog -- Version 2
Nat Gopalswamy, Grzegorz MichaÅek, Seiji Yashiro +4
This paper provides an update on the coronal mass ejection (CME) catalog maintained at the CDAW Data Center, NASA Goddard Space Flight Center (https://cdaw.gsfc.nasa.gov/CME_list).…
