[1] Message from the ISWI Executive Director

Dear ISWI colleagues,

As you all know, the world is battling COVID-19. Therefore, almost all meetings have been canceled until the fall of this year. Most of us are working from home and this is a great opportunity the read literature on space weather and catch up with those pending papers you always wanted to complete. I am sure you are all participating in online meetings and seminars. Last week, I enjoyed a talk by Nobel Laureate John Mather on Big Bang, Hubble Space Telescope, and the soon-to-be launched James Webb Space Telescope. The talk provided a universe-context to the Sun and the life it supports on the unique planet Earth.

As scientists, we know how the virus spreads and how we can quench it by physical distancing, washing hands, and taking all precautions that have been suggested by the healthcare/medical communities. Stay safe!

Best, Nat Gopalswamy

[3] Summer School and Conference in Nonstationary Signal Analysis in Geophysics and other fields (NoSAG) postponed

[This event was originally announced in the ISWI Newsletter, Vol. 12, Number 3]

The Organizing and Program Committee of the first Summer School and Conference in Nonstationary Signal Analysis in Geophysics and other fields (NoSAG) that was planned to be held in L'Aquila, Italy in July, regret to inform that , given the undergoing pandemic and concurrent social and economic disruptions, NoSAG whole program will be postponed to *SUMMER 2021.*

We sincerely hope that the entire scientific community and their families will be able to remain healthy during this dramatic time and that the extraordinary efforts underway to contain the coronavirus and to preserve the economic security will be soon successful.

Best regards,
A. Cicone Chair, Org. Com. M. Piersanti Chair, Prog. Com.

ABSTRACT

Due to the secular variation of the geomagnetic field, for the past few decades, the dip equator is showing a southward migration and in the Indian subcontinent it is currently crossing Sri Lanka. The main purpose of this proposed project is to establish a data gathering point in this part of the world close to dip equator to fill the vacuum. Preliminary studies on the selection of a site was made in February, 2016. One hour measurements were taken using a MAGDAS-9 magnetometer in several locations close to the places in dip equator till a place with field variations less than 400 nanotesla is found. A site in Dompe area (36 km away from Colombo) was finally selected (6.97⁰N, 80.07⁰E). The installation of the magnetometer required a metal free construction. Two brick and cement enclosures each of 1.2×1.2×0.5 m size pit, one for the magnetometer, and other for the amplifier (about 5 m away from the magnetometer), in the selected area was constructed under the ground and the magnetometer was installed. Magnetometer was aligned to get minimum errors on X, Y and Z components of the magnetic field. A 200 m long cable from the amplifier was connected to a data logger inside a safe place in a nearby shelter with electricity supply. A 4G router was connected to the data logger for continuous uploading of data to MAGDAS world network. A GPS instrument too was connected to the data logger. A 12V car battery was fixed to run the data logger in dc power while the battery is charging from AC mains to avoid interruptions due to power possible power failures. It was found that the magnetometer installed was functioning perfectly. Geomagnetic latitude and longitude of the observatory and the dip latitude are -1.65, 152.90 and -0.34, respectively.
