Roughly every 67 days, Tendril begins a 12- to 14-day Bum. The electromagnetic radiation shed by the star during this period increases by a factor of 20, bombarding the star’s planets and moons with deadly cosmic and ultraviolet rays. When using the GRAPH system to evaluate environmental conditions, the radiation (H) value increases by one grade during a Burn. For example, Delphin is usually rated R4; during a Burn, it’s R5.
The Burn’s other effect is to disrupt electronic equipment within the system. All skill checks using System Operation- sensors or communications suffer a +2 penalty during a Burn
