The Moon will reach its first quarter on Tuesday, June 3 at 5:41 CEST.
At the beginning of the week, it is in the constellation Leo, and on Sunday it appears between Mars and Regulus.
Solar activity has recently been high but is now decreasing again.
There are several active sunspot regions, but only one currently has potential for larger flares.
You can monitor sunspot activity on the latest SDO imagery.
