A Type II Radio Emission with an estimated velocity of 988 km\/s was registered at 02:43 UTC, indicating a coronal mass ejection (CME) was associated with the event.<\/p>\n
Active Region 4299 is located on the Sun\u2019s northeastern limb, limiting the possibility for Earth-directed CMEs. However, this will change as the week progresses, and the region moves toward a geoeffective position.<\/p>\n
This is the old Region 4274, source of multiple X-class flares during its last rotation over the Earth-side in early November, including X5.1 on November 11, which produced the strongest Ground Level Enhancement event in 20 years.<\/p>\n
Other notable flares from this region include X4.0 on November 14, X1.7 on November 9, and X1.2 on November 10.<\/p>\n
Radio frequencies were forecast to be most degraded over Australia at the time of the flare event.<\/p>\n
\u201cThis storm is not Earth-directed (it is directed towards Saturn), but I would not be surprised if we see a radiation storm rise at Earth over the next few hours,\u201d Space Weather Physicist Dr. Tamitha Skov said.<\/p>\n
\u201cPreliminary analysis of the recent X1.95-flare shows radio bursts of over 1.2 GHz observed at the new Wairakei SIGN station in New Zealand,\u201d Skov said.<\/p>\n
\u201cThis means this region has the potential to temporarily disrupt GPS\/GNSS, satellite phone, and ADS-B airline transponder communications when it flares! Stay vigilant if you use these services while on the dayside of Earth!\u201d<\/p>\n
