Abstract Plasma variations in geospace environment driven by the solar wind-magnetosphere interaction is one of the major causes of satellite anomaly. To mitigate the effect of satellite anomaly, risk of space weather disturbances needs to be known in advance based on space weather forecast. However, risk of satellite anomaly due to space weather disturbances is not the same as each satellite, because the risk depends not only on the space environment itself but also on the design and materials of individual satellite. For the viewpoint of satellite operator, it is not easy to apply general alert level of space environment to the risk of individual satellite. To provide tailored space weather information, we have developed SECURES (Space Environment Customized Risk Estimation for Satellite) by combining models of space environment and those of spacecraft charging. In SECURES, we are focusing on the risk of spacecraft charging (surface/internal) for geosynchronous satellites. For risk estimation of surface charging, we have combined the global magnetosphere MHD model with the satellite surface charging models. For risk estimation of internal charging, we have combined the radiation belt models with the satellite internal charging models. We have developed prototype products for both types of charging/ESD. The development of SECURES and our achievements are introduced in this paper.

Weather Impacts

<p>For the UK, the potential impacts from severe space weather (and everyday space weather) are considered of a high importance and hence the UK Government has included “Severe Space Weather” on its National Risk Register of Civil Emergencies since 2011.  This is not just considering direct impacts on UK infrastructures, but also impacts to key partner/trading/neighbouring nations.  This has led to a long series of national and international engagements and strategic developments both between UK agencies/entities and with international agencies/organisations (such as ESA, NOAA, NASA, COSPAR, ISES, ICAO, WMO, and UN COPUOS).  On top of this, the UK has undertaken a series of wide-ranging investigations to mitigate space-weather impacts at the national level including the ongoing development of a national Space Weather Strategy – where the UK looks to experts across all sectors to feed into its development.</p><p> </p><p>An essential aspect of trying to mitigate space-weather impacts on the UK is the need for independent UK space-weather forecast capability in collaboration with the other 24/7 space-weather forecasting institutes around the World.  This UK capability allows for direct advice to government on all things space weather, particularly on what to do when an impending event is expected and throughout its duration and recovery.  Hence, he setting up of a UK staffed 24/7 space-weather forecasting centre at the Met Office alongside the formation of the Space Environment Impacts Expert Group (SEIEG) of experts were undertaken to provide the necessary advice to government.</p><p> </p><p>The UK is currently committing a large amount of money both to dedicated UK-based and ESA-based space weather programmes as well as through traditional science research funding channels.  This includes the UKRI Strategic Priorities Fund (SPF) Space Weather Instrumentation, Measurement, Modelling and Risk (SWIMMR) programme and the ESA Space Safety Programme.  The UK has also taken a lead on several other space-/ground-based space-weather endeavours that are proving highly complementary to current UK and global capabilities.</p><p> </p><p>In this presentation, we will provide an overview of the above along with any outline of the UK Space Weather Strategy open to the public at the time of the EGU 2020 Meeting.</p>

Complex Knowledge

In our era, the epoch of the mass media, the simplest and the most complex knowledge and experience is being increasingly presented or jointly shaped by young journalists, junior editors or relatively young media owners. The state of youth generally corresponds with more insufficiently articulated bright and classic, literary and timeless knowledge. Furthermore, the state of youth, which dominates the mass media scene in our environment, does not have enough field of experience as important guideline of a good professionalism. In theory, good information is a result of three journalist’s experience: the experience of a specific message (event), the earlier experience and pervious level of education. Now, how to compensate the leak of one of those elements on everyday basis? I am going to analyse a very simple, generally known and very important example in the „world of life” – the matter of „weather forecast” or „weather information”. It is becoming important yet even more sensational. For media credibility, even regarding this information, the classic and background knowledge is exceedingly important in addition to modern views „through telescopes-satellites”.

Exponential Smoothing Method

The paper presents information on the results of short-term space weather forecasting for the Vostochny cosmodrome based on data on the electron flux density with energies above 2 MeV received from satellites from the operator's site of the Space Weather Forecast Center of the Moscow State University Institute of Nuclear Physics. The analysis of the calculated data on the level of near-Earth radiation, as a result of the use of various extrapolation methods, showed that the method of exponential smoothing is most effective for short-term space weather forecasting. Such forecasts can be used when planning launches of launch vehicles from spaceports.
