uring the solar cycle, a significant variation in solar
irradiance is observed in EUV, UV and X-ray
wavelength regions. To understand this variation, thesegmentation of solar soft X-ray and E(UV) full-disk
images for a longer period is necessary. We started with
Hinode/XRT data of full-disk soft X-ray images of thesolar corona and segmented it into its different features:
Active Regions (ARs), Coronal Holes (CHs), Background (BGs), X-ray Bright Points (XBPs) and Limb forthe period from February 01, 2008 to June 17, 2023.

Meeting Reporturoras typically occur along an oval enclosing thepolar cap void of emissions, driven by southward
interplanetary magnetic field. Theta auroras occur predominantly during northward IMF, forming an unusual
bar of auroral light stretching across the dark polar cap
from dayside to nightside in a shape resembling the
Greek letter theta (Figure 1a) [1]. Though northward
IMF is assumed to lead to quiet magnetospheric conditions, the existence of theta aurora indicates transfer ofsolar wind energy into the magnetosphere, with magnetic topology more complicated than previously assumed.

fter a careful examination of the of the movies
available in the PE catalog, we checked the association between these prominences and the CMEs. We set
a confidence level (CL) from 0 to 5 for this association.
The CLs are based on the quality of the association: 0
for no association and 5 for clear association. Out of the1225 PEs, 662 (54 %) are associated with CMEs for CL
1–5. For clarity, we consider only CL5 events and foundthat 78 % of the associated CMEs shows clear brightcore. The average speed of prominences associated with
CMEs, CME core, and CME leading edge are found to
be 62, 390, and 525 km s−1, respectively. The highest
speed of CME leading edge is be explained using
Maričić et al. (2009) when they demonstrated that therate of acceleration for the leading edge of CME is approximately twice of PEs. Morphological and heighttime analysis of prominences and CME cores reveals
that the prominence material at greater height becomes
the CME core (Figure 1).

Meeting Reportn 17 November 2023, the International Space
Weather Coordination Forum (ISWCF) was held at
the World Meteorological Organization (WMO), Geneva, Switzerland, and I joined as the representative of
SCOSTEP. This in-person invitation meeting was heldby a joint initiative of the WMO, the International Space
Environment Service (ISES) and the Committee on
Space Research (COSPAR), intending to shape the future of international collaboration on Space Weather
with the aim of increasing the community’s ability to
mitigate Space Weather threats. These three organizations (WMO, ISES, and COSPAR) are taking initiatives
in this respect in response to the recommendation in the
final report (A/AC.105/C.1/L.401) of the Space Weather
Expert Group of the United Nations Committee on thePeaceful Uses of Outer Space (UN-COPUOS). UNCOPUOS called upon WMO, ISES and COSPAR tolead efforts to improve the global coordination of space

imed at bringing awareness on space weather to themasters students of science and engineering in India a “Workshop on Space Weather Science and Opportunities” was organized by PRL during 17 – 18 October.
Over 340 students (hybrid attendance) that signed up
from 127 universities and 25 states across India were
taught by the PRL faculty on the topics of the sun, theintervening medium, the earth’s upper atmosphere andhow the adverse space weather effects affect the satellite
orbits, communication, navigational and GPS applications, electric grids on the ground, enhanced radiation

for aviation travelers, among others. Laboratory visitswere also conducted with demonstrations on the wide
spectrum of ground- and satellite-based experiments
developed in-house in PRL. This Workshop was followed by the “2nd Indian Space Weather Conference(ISWC-2)” (19-20 October 2023). In addition to science
results, presentations on payloads of Aditya-L1 and future aeronomy missions were made in the ISWC-2.

he 19th edition of the European Space Weather
Week was held in Toulouse, France, in November
2023 (esww2023.org). The spirit of this series of conference is to gather all the actors of space weather, fromresearch labs to private companies and operational centres. About 700 registered participants (including about
100 online attendees) took part in classical plenary sessions as well as splinter sessions, either scheduled by
the program committee or suggested by the community.

The conference was preceded by satellite events such asa training school for young scientists, ISWAT working
sessions and a sustainability workshop. To make themost of the opportunity, a number of public and schooloutreach initiatives were carried out, such as a space
weather village, public lectures and other activities. The
European Space Weather Week in Toulouse was sponsored by the SCOSTEP/PRESTO programme.

Meeting Report
Upcoming Meetingsr. Nat Gopalswamy is an eminent scientist who
has made outstanding contributions to the scientific understanding of solar coronal mass ejections andtheir space weather consequences, as well as other areasof solar-terrestrial relations, and who contributed muchto international scientific collaboration. Coronal massejections affect the whole interplanetary space and are
responsible for the strongest geomagnetic storms, impacting not only geospace but also space-based andsome ground-based human technologies. His work is
well demonstrated by the publication of more than 400
papers in refereed journals. He has served as a Principal
Investigator, Co-Investigator and Team Member on various space-based experiments. Dr. Gopalswamy received more than twenty different scientific awards,
reflecting the high level of his scientific activities. He
has served as an associate editor of both the Journal ofGeophysical Research and Geophysical Research Letters; since 2006 he has been scientific editor of Sun andAnnouncement
