    Busy day upstairs.

    Two coronal mass ejections inbound,around 31 /3 (zulu)

    Larger risk of outages in High Latitudes (small but distributed)

    Not a good time to be a satellite owner.

      small storm, large sunspot (well 2x size of earth)

      Context, solar cycle 25 began in 2019 (11 years) its activity peak is c2025 (its magnetic poles flip mid cycle) and then activity falls away.

        One forecast is for more sunspot activity for this cycle than expected.

        The context of the solar cycle is irrelevant as large flares and CME can occur at any stage of the SC.

        The warming of the Thermosphere ( due to increased proton flux) increases drag on satellites which can reduce orbit if not properly corrected.(like last month)

        The risk here is in high latitudes where Geomagnetically induced currents can occur in HV transmission networks (such as the November event 2001which took out the transformer at half way bush)

        During space weather events the interaction of coronal mass ejections and high-speed streams with the Earth's magnetic field gives rise to electric currents flowing in the ionosphere and magnetosphere. The magnetic field variations associated with these currents during geomagnetic disturbances induce an electric field at the Earth's surface through an interaction with the conducting ground. The electric field induced during these disturbances leads to an electromotive force in long conductors such as electrical transmission lines causing currents to flow along the conductors. These geomagnetically induced currents (GICs) can cause a direct current (DC) offset current to flow through the windings of transformers connected to the transmission lines at substations. GIC can damage transformers through magnetic saturation of the material in the transformer's core, which leads to overheating and generation of harmonics

    On a more light hearted note:

    Yes. Its in the side bar. Jesus that photo. Note he's wearing a chain and cross around his neck. He does nothing for me. sad
