SOLAR CYCLE 25 ACTIVITY REPORT JUN 20
▪︎Geospace quiet
▪︎Latest Solar wind speed record: 585.7 km/sec ( 13:33 UTC Jun 20)
▪︎density: 16.5 protons/cm3
▪︎Neutron Counts today: 1.7% Elevated
▪︎Sunspot number: 120 (SN149 June 19)
▪︎Geomagnetic conditions now Kp=2 (13:57 UTC Jun 20) quiet
▪︎AR3038 enormous size. Last friday this region had an area of 10 millionth of a solar hemisphere (MH) its size is now 140MH (Earth’s area is almost 170 millionths by comparison!) It is a region composed of 17 sunspots with a beta-gamma magnetic field.

AR 3038 has doubled in size since yesterday as it moves into a direct Earth facing position. So far the region has only managed minor C-Class solar flares. This region will be monitored for further development and could be an increased threat for a moderate M-Flare. pic.twitter.com/WMeyZX0rPd

This is an X-ray full-scale image of the Sun on June 19, 2022. You can see 9 groups of corona loops in the active area 13030-13035 / 13037-13039. There is a coronal hole (dark area) in the middle of the east (left) direction near the northeast (upper left) and southeast (lower left) edges.
