Later, the Institute of Applied Geophysics named after Fedorov reported that three strong class M solar flares occurred on Thursday. 'On July 02 at 04:56 MSK, an M4.2 flare lasting 27 minutes was recorded in the X-ray range within spot group 4479 (N18W31),' according to the statement.
Consensus
- Active solar region 4478 has become the second largest in size over the past decade
- The active region 4478 reached an area of 1,550 units
- A second active region, 4479, is also growing and located approximately half a million kilometers to the northwest of the main spot
- Solar activity has sharply increased over the past day
- Scientists expect plasma ejections from these regions to reach Earth within 24 hours
- The impact on Earth may result in geomagnetic storms at levels G2-G3
- The Sun's rotation is moving active centers away from Earth toward the west
- By the weekend (July 4-5), solar activity will likely no longer affect Earth due to positioning of these regions
