Short-term predictions

Definition

Short-term predictions refer to forecasts made about solar and heliospheric phenomena that are expected to occur within a brief timeframe, typically ranging from hours to days. These predictions are crucial for understanding the immediate effects of solar activity on space weather, which can impact satellite operations, communication systems, and even power grids on Earth. By utilizing real-time data and models, scientists can make timely decisions to mitigate the potential adverse effects of solar events.
