Energy sensitivity of the GRAPES-3 EAS array for primary cosmic ray protons
B. Hariharan, S. Ahmad, M. Chakraborty +23
Low energy ground-based cosmic ray air shower experiments generally have energy threshold in the range of a few tens to a few hundreds of TeV. The shower observables are measured i…
Measurement of the Electrical Properties of a Thundercloud Through Muon Imaging by the GRAPES-3 Experiment
B. Hariharan, A. Chandra, S. R. Dugad +19
The GRAPES-3 muon telescope located in Ooty, India records rapid (10 min) variations in the muon intensity during major thunderstorms. Out of a total of 184 thunderstorms rec…
Was the cosmic ray burst detected by the GRAPES-3 on 22 June 2015 caused by transient weakening of geomagnetic field or by an interplanetary anisotropy?
P. K. Mohanty, K. P. Arunbabu, T. Aziz +19
The GRAPES-3 muon telescope in Ooty, India had claimed detection of a 2 hour (h) high-energy (20 GeV) burst of galactic cosmic-rays (GCRs) through a 50 surge in GeV muo…
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…
How are Forbush decreases related with IP magnetic field enhancements ?
Arunbabu K. P., P. Subramanian, Sunil Gupta +1
Cosmic ray Forbush decreases (FDs) are usually thought to be due to Earth-directed coronal mass ejections (CMEs) from the Sun and their associated shocks. When CMEs and their shock…
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…
