#Weekly Highlights and Forecasts

Highlights of Solar and Geomagnetic Activity 08 - 14 April 2019

Solar activity was very low throughout the period. Region 2738 (N06, L=297, class/area Cho/300 on 12 Apr) produced numerous B-class flare activity and low frequency radio burst activity. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels thoughout the period.

Geomagnetic field activity was at quiet to unsettled levels on 08-13 April due to negative polarity CH HSS influence. Isolated active levels were observed early on 08-10 April. Quiet levels were observed on 14 April.

March 2019's regions

Region 2736 was March 2019's big surprise!

This region (N08-283) suddenly appeared on March 22

at W35 of CM as a Dac 50 mvh. The region quickly developed and according to NOAA reached EKI (CV=47) 420 mvh big and by that the largest region since 2017 Sep10!

Region 2736 disappeared behind western limb already on the 24th,

but it appeared that it actually returned April 7th.

In these minimum-approach days this was a bit like against all odds,

but wonders do happen still! Region 2736 produced 12 C-class x-ray-flares and 43 optical flares!

More in next issue!

No new Awards this month

Upcoming observations from new observer

CV-212 Antonio Jesús Zapata Morales

will start his CV-observations commencing April

We are now 52 active members

Please check out www.cv-helios.net/cvrep2.html for updates of files!

MINIMUM Cycle 24/25 is expected to occur between November 2019/May 2020. Latest: Predicted minimum April 2020. Value: Approx. 2008/2009 low values.
