#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 08 - 14 June 2020

Solar activity was at very low levels throughout the period. Region 2765 (S24, L=116, class/area Cao/130 on 05 Jun) produced a B1 flare at 09/0311 UTC but was otherwise stable and unremarkable. No Earth-directed CMEs were observed in available imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels throughout the reporting period.

Geomagnetic field activity was at mostly quiet levels with isolated unsettled intervals on 09-10 June due to CH HSS influence.

Forecast of Solar and Geomagnetic Activity

15 June - 11 July 2020

Solar activity is expected to be at very low levels.

The page also gives you a link to the year table.

A new feature at CV-Helios Network has been tried out and published on web as a help for those of you in need for heliographic data, the nearest 28-day table over Po, Bo and Lo with Carrington Rotation number, Sundiameter in arc minutes and also the RA and Dec.

This, together with the updated SOHO-image with the correct grid as an overlay, is published every day before 9 am UTC and is sometimes updated during daytime.
