Interplanetary magnetic flux rope observed at ground level by HAWC
S. Akiyama, R. Alfaro, C. Alvarez +59
We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Ear…
Galactic Cosmic Ray Sun Shadow during the declining phase of cycle 24 observed by HAWC
Alejandro Lara, Paulina Colin, K. P. Arunbabu +1
The High Altitude Water Cherenkov (HAWC) array is sensitive to high energy Cosmic Rays (CR) in the to TeV energy range, making it possible to construct maps of…
How are Forbush decreases related to interplanetary magnetic field enhancements ?
K. P. Arunbabu, H. M. Antia, S. R. Dugad +6
Aims. Forbush decrease (FD) is a transient decrease followed by a gradual recovery in the observed galactic cosmic ray intensity. We seek to understand the relationship between the…
Self-similar expansion of solar coronal mass ejections: implications for Lorentz self-force driving
Prasad Subramanian, K. P. Arunbabu, Angelos Vourlidas +1
We examine the propagation of several CMEs with well-observed flux rope signatures in the field of view of the SECCHI coronagraphs aboard the STEREO satellites using the GCS fittin…
High rigidity Forbush decreases: due to CMEs or shocks?
Arun Babu, H. M. Antia, S. R. Dugad +7
We seek to identify the primary agents causing Forbush decreases (FDs) observed at the Earth in high rigidity cosmic rays. In particular, we ask if such FDs are caused mainly by co…
