2025-07-16 Synoptic Map — CR 2300.01 (16.7.)
Developments in the northwestern cluster and equatorial region 4142 have caused the sunspot number to rise above 200 again for months. The sun's activity is increasing. The coronal hole CH63+ is slowly losing its influence—the two coronal holes in the east still need a week before they can have an impact on us.

The images are composites of SDO AIA 171/193/211 Å and SDO HMI continuum + SDO HMI magnetogram. The neutral line was determined from the HMI magnetogram, H-alpha filaments from H-alpha-filtered images of the GONG network, active regions from HMI continuum + magnetogram, coronal holes from SDO 193 and 211 Å, the numbering of the active regions was taken from the SWPC website, that for coronal holes from the synoptic map of MOSWOC (MetOffice UK Space Weather Operations Centre) or the synoptic map of SWPC. The Mt. Wilson classification follows MOSWOC or SWPC or, in case of doubt, own judgement.

The grid with the Carrington coordinates, which move with the sun’s rotation, comes from JHelioviewer.

The composite image was created with JHelioviewer. The aim is to meet scientific findings/criteria, to provide an overview for personal or operational space weather reports and to simplify forecasts for the solar wind, to enable comparisons with previous rotations (position and size of coronal holes, development of active regions – finding ‘hot longitudes’) and finally to conjure up something pretty on the screen.
