公告

Solar activity has been marked by C-class flares from an active region rotating into view from the east limb. It produced a C9.9 flare peaking at 11:42 UT. M-class flares from this region are likely. Geomagnetic conditions have been quiet. A relatively fast solar wind stream has arrived to ACE this morning, with strong magnetic fields reaching 20 nT. So far containing only northward directed fields (positive Bz). If Bz turns south, then active to minor storm levels can be expected.

今日估計的國際太陽黑子數（ISN）：031，基於05個觀測站。
