#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 08 - 14 March 2021

Solar activity was very low on 08 and 10-14 Mar. Low levels of solar activity were observed on 09 Mar due to a C1 flare at 09/1235 UTC, from Region 2808 (S19, L=035, class/area, Cao/30 on 12 Mar). 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 high levels on 08-12 and 14 Mar, with moderate levels observed on 13 Mar.

Geomagnetic field activity reached G1 (Minor) geomagnetic storm levels on 14 Mar, with active levels on 13 Mar due to recurrent, negative-polarity CH HSS influence. Quiet to unsettled conditions were observed for the remainder of the reporting period (08-12 Mar).

News February 2021

Solar activity is nearly at standstill in this phase of the new solar cycle 25. The rapid rise we saw in November 2020 and some of it in December 2020, have now gone into a stage of near standstill in activity.

No very large activity sunspotwise has been seen lately, but solar wind has been rising steadily since last summer.

Region 2804, at lat. S19, long. 309 (2241), was at 190 mvh on 25 February, a fairly interesting group that soon after started decaying but managed to exit round west limb.

There should be a chance of higher activity during March and April.

CV-HELIOS NETWORK GRAPHIC FILES

The graphic files menu at www.cv-helios.net has undergone some changes lately,

and will be updated every month on the 15th in due time for the MPR to be issued.

NEW MENU: DAILY RUN FILES

Located via the "Misc."-menu at https://www.cv-helios.net/cvmisc3.html:

DAILY RUN FILES

giving you daily updates on DAILY SOLAR & CV-REPORTS, CV-OBS. REG. UPDATES,

TEXT LIST & TABLE DAILY CV-INT., CV-USAF NUMBERS & NOAA/USAF SUNSPOT REGIONS, SOHO GRIDDED IMAGES AND POSITIONAL TABLES, SOLAR FLUX & P-INDEX, SOLAR WIND.

The menu is dynamic in the green background fields, meaning it is date-dependant and should be available from about 10:00 UTC until local midnight.

NEW MENU: GRAPHICS/OBSERVATIONS/OBSERVER STATISTICS: The new graphics page over CV-Int., observations and observers

is now ready from the main page or go to https://www.cv-helios.net/cvobsgraph.html The page is updated every time new submissions have been registered.

New or revised features may appear in time.
