Evolution of helicity in NOAA 10923 over three consecutive solar rotations
Sanjiv Kumar Tiwari, Jayant Joshi, Sanjay Gosain +1
We have studied the evolution of magnetic helicity and chirality in an active region over three consecutive solar rotations. The region when it first appeared was named NOAA10923 a…
