The Sun – Active Region 1429 – Beware of X-Class Flares !

Huge active region AR1429 is looking rather benign now as it nears the western limb of the sun’s disk, but just five days ago it produced the largest solar flare of the current solar cycle, an X5 class eruption at 00:28 UT on the 7th March. On the 9th and 10th March it continued to flare at M class levels and large Coronal Mass Ejections (CME’s) were hurled our way on each occasion which will soon be providing plenty of aurora activity in the northern polar regions. Fortunately the cloud parted this afternoon to give me a clear view of this impressively active sunspot group so I took the opportunity to capture it in the CaK and Ha light wavelengths. The hydrogen alpha views show a huge curving filament snaking across the eastern limb. Images taken 12.32- 13.09 UT using Coronado Ha PST/Lunt CaK wedge at 100mm/DMK 41 camera
