SCOSTEP Launches VarSITI Program to Explore the Origin and Consequences of a Weak Sun
Written by Jaša Čalogović Monday, 13 January 2014 13:52
Although the Sun just recently provided strong flare on 7th January 2014, 18:30 UTC connected with coronal mass ejection (CME) and this time luckily with minor impact on Earth, the current 24 solar cycle is in general much weaker than previous solar cycles. That something is changing on the longer timescales related to solar activity was already indicated by the number of spotless days in the last solar minimum which was the largest in last century. To investigate rather unusual solar cycle in the last year MiniMax24 campaign was started, leaded by Manuela Temmer from Graz University, where Hvar Observatory was also involved with expertise and Hvar solar Telescope observations. The continuation of this campaign in now foreseen in new scientific program called VarSITI (VARiability of the Sun and Its Terrestrial Impact).
One of the scientific elements of VarSITI is ISEST (Internatinal Study of Earth-affecting Solar Transients) which tries to understand the origin, propagation and evolution of solar transients through the space between the Sun and the Earth, and develop the prediction capability of space weather. In the frame of ISEST last year (2013) the ISEST workshop on Hvar was organized in June.
Beside the ISEST, Hvar Observatory performs also research on solar activity influences on Earth’s climate and weather (ROSMIC). There are still many contended mechanisms that link the solar activity and Earth’s climate. If such weaker solar activity continues in the future, it will be interesting to observe the eventual climatic changes linked to solar activity in the next decades.

New version of Drag-Based Model (DBM)
Written by Jaša Čalogović Friday, 25 January 2013 18:21

The new version of DBM now includes the advanced DBM which provides this output for any target in the heliosphere and takes into account also the shape of ICME employing the so-called cone-geometry. Plots showing the impact speed depending on the distance from the Sun (v-R) and CME geometry are added to the model outputs.
