Another Mini Solar Maximum in the Offing: A Prediction for the Amplitude of Solar Cycle 25
Susanta Kumar Bisoi, P. Janardhan, S. Ananthakrishnan
We examine the temporal changes in both solar polar magnetic field (PMF) at latitudes and heliospheric magnetic field (HMF) at 1 AU during solar cycles 21--24 wi…
CALLISTO Spectrometer at IISER-Pune
K. Sasikumar Raja, Prasad Subramanian, S. Ananthakrishnan +1
A CALLISTO spectrometer to monitor solar radio transient emissions from (above photosphere) is installed at IISER, Pune, India (longitude $73^{\circ} 55…
A Twenty Year Decline in Solar Photospheric Magnetic Fields: Inner-Heliospheric Signatures and Possible Implications?
P. Janardhan, Susanta Kumar Bisoi, S. Ananthakrishnan +4
We report observations of a steady 20 year decline of solar photospheric fields at latitudes 45 starting from 1995. This prolonged and continuing decline, combi…
Changes in quasi-periodic variations of solar photospheric fields: precursor to the deep solar minimum in the cycle 23?
Susanta Kumar Bisoi, P. Janardhan, D. Chakrabarty +2
Using both wavelet and Fourier analysis, a study has been undertaken of the changes in the quasi-periodic variations in solar photospheric fields in the build-up to one of the deep…
The Prelude to the Deep Minimum between Solar Cycles 23 and 24: Interplanetary Scintillation Signatures in the Inner Heliosphere
P. Janardhan, Susanta Kumar Bisoi, S. Ananthakrishnan +2
Extensive interplanetary scintillation (IPS) observations at 327 MHz obtained between 1983 and 2009 clearly show a steady and significant drop in the turbulence levels in the entir…
Occultation of the radio source 2019+098 (3C411) by comet 1983e (Sugano-Saigusa-Fujikawa)
S. Ananthakrishnan, Dilip G. Banhatti
[This cometary occultation observation from June 1983 remained to be formally reported due to other preoccupations of the authors. It was presented in seminars to colleagues at Oot…
