Proxima Centauri c
Atmospheric Albedo 0.79
Semi-major Axis 0.0235AU - 0.0196AU
Orbital Period (days) 2.87 days - 3.765 days
Temperature 250K - 273K
Description: albedo of 0.79 specifies a range for cumulus stratus (low altitude cloud) or fresh snow, both viable at -23 degrees Celsius. While albedo 0.3 specifies ice in the planetary rings.
Low altitude methane clouds, and an Ice Ring.

Proxima Centauri c / Rawn 2.87 - 3.765 0.0196 - 0.0235 0.79 250K - 273K
Description: low altitude Cumulostratus Methane cloud blankets the entire planet while Ozone/Water Ice rings extend to about 2R of the planet Radius. The substantial Partial Ring gap indicates an off-axis moon or a chance encounter with a rogue moon.
Radius: Proxima Centauri itself has a radius of 0.1542Rsolar. Based on an examination of the hubble photo the planet has about 1/10th - 1/20th of Rproxima. 1Rsolar is about 10RJupiter so we are looking at a 1.5RJupiter- 0.76RJupiter planet. Our own Jupiter has at least four descent sized moons and a strong magnetic field so it could have a number of habitable zone moons with water.

Description: Ozone cloud appears to blanket the entire planet. That seems to suggest intense electrical storms or industrialization. The range on the orbital period is rather diverse. Water vapour atmosphere is going to mean this is planet Tao as opposed to a colossal range that is offered by ozone.
