With my dear colleague Gherardo Valori from MSSL, we are organising a focused team on the estimation of magnetic helicity. This team is meeting under the patronage of the International Space Science Institue (ISSI) in Bern, Switzerland.
The name of the team is: Magnetic Helicity estimations in models and observations of the solar magnetic field
You can visit the team website to check our activities. The first meeting of the team took place on the first week of december.
