First Announcement: European Space Weather Week 2026 call for convening of
sessions and discussion meetings, 2nd - 6th November 2026, Florence, Italy

From: Kamen Kozarev <kkozarev - at - astro.bas.bg> and Michele Piana <

European Space Weather Week (ESWW) 2026 will be held in Florence, Italy
from 2nd - 6th November in a hybrid format. The overarching theme for
ESWW2026 is ‘Data-driven and physics-based cross-scale space weather and
space climate’.
The ESWW conference is an excellent opportunity for people from all over
the world to gather and discuss the most recent insights in space weather
and space climate, and to address the emerging challenges and impacts.
Science, observations, data exploitation, data standards and metadata,
service development, operational models, engineering and industrial needs
are all important aspects of the field that are addressed.
One of the strengths of ESWW is that participants can contribute
significantly to its content through Parallel Sessions, Plenary Sessions
and Topical Discussion Meetings (TDMs). The ESWW Programme Committee (PC)
and Local Organising Committee (LOC) are pleased to announce that the call
for the convening of these sessions will be open during the following time
window:
Opening date - 16th February 2026
Closing date (plenary and parallel) - 20th March 2026
Closing date (TDMs) - 3rd April 2026
A short synopsis of each element is given below. More information will be
made available on the ESWW2026 website in due course:
https://esww2026.eswan.eu/

Plenary Sessions
This year, the ESWW will host four plenary sessions.
* Two plenary sessions will be dedicated to topics proposed by the
community. Here, the community is invited to submit proposals to convene.
Plenary session proposals are invited covering one or more of the following
topics: modelling, data analysis, instrumentation, observations and
measurements, end-user needs and applications, and R2O2R. The proposed
sessions must fit within the theme of the conference, “Data-driven and
physics-based cross-scale space weather and space climate”.
Proposals are sought that are engaging, of a particularly high-standard,
relevant to the broader space weather and space climate community, and
designed to stimulate discussion and debate.
* The other two plenary sessions will feature distinguished presentations
proposed by the convenors of parallel sessions, promoting parallel sessions
to a broader audience. As such these sessions will not be part of this call.

Parallel Sessions
This year ESWW PC decided to implement a new format for parallel sessions.
Those interested in convening a session at ESWW2026 may submit a proposal
to one of the following Topics:

SOL - The Sun and Solar activity
HEL - Heliosphere (including , e.g., solar wind, ICMEs, SEPs, GCRs, SW
effects on other planets, etc.)
MIT - Magnetosphere/Ionosphere/Thermosphere
SWI - SW effects on Infrastructure
SCL - Space Climate
IOM - Instrumentation, Observation techniques, and Missions (including,
e.g., sessions related to end-users and applications)
OTH - Other topics

Proposers have the freedom to choose the title for their session. In the
session description, the motivation and the reason why the proposed session
is relevant for this year should be provided in one or two sentences. The
proposed session may be a general one or focusing on a specific subject
related to a selected Topic.

A single OPS session is intended, which will welcome submissions on
research topics related to Space Weather and Space Climate but not covered
by any other focused sessions. The OPS session will be proposed by the PC
and a team of conveners to lead such session will be announced later. One
member of the PC will join the team to offer support.

The PC strongly encourages those who have not previously proposed a session
to do so. In line with our commitment to diversity and inclusion, we
welcome and encourage applications from conveners of all backgrounds,
including but not limited to, different career stages, geographical
locations, ability, genders, and ethnicities.


Topical Discussion Meetings
Topical Discussion Meetings (TDMs) are an important component of the
European Space Weather Week (ESWW) – a format meant to facilitate engaging
debates within the heliospheric, and space weather and space climate
communities. These meetings provide the opportunity for interested
participants to address key issues in a community forum style that
complements the conference sessions. Potential conveners must describe in
dedicated fields of the proposal form the target community, the expected
outcome of the meeting, and its potential impact. After the selection of
the proposed TDMs is made, the proposers will be informed in Q2 of 2026.
