Properties of the modelled open solar flux variations with/without the addition of SC4b compared with observed 10Be, 14C and auroral variations.
| B*(OSF) no SC4b | B*(OSF) with SC4b | B*(10Be) | NA* | 14C production | |
|---|---|---|---|---|---|
| Time of primary SC4 peak | 1788 | 1790–1792 | 1789 | 1788 | – |
| Amplitude of SC4 peak relative to SC2 and SC3 | Smaller | Larger | Larger | Larger | Larger |
| Secondary peak in 1794–1799? | Yes | No | Yes | No | – |
