| Catalogue: | none |
| Filter: | 540nm continuum filter and ND1.8 filter |
| Class: | Solar system |
| Comment: | Sunspot 3392 is breaking up, because the role of the magnetic field, which contributes to the pressure such that the thermal pressure and temperature is lowered, is weakening. The convective granulation cells can be seen around the sunspot. Equipment: 130mm f/7 apo, Baader Herschel wedge, Baader FFC Barlow at 3.5X, ZWO ASI 120MM-mini camera. |
