Explain, why would we not see visible evidence of sublimation?
What visible evidence of a diffuse colorless gas would you expect to see, exactly?

Well, what's different between the two situations?
One is a spacecraft without people in it, with all the equipment shut down.
The other is spacecraft with people in it, with all kinds of constantly-running equipment.
The heat they have to get rid of isn't from the sun. It's the heat generated *inside* the spacecraft they have to get rid of.

And as we have shown in this thread: Major Solar Flares, Majore SPEs all occurred during Apollo.
And we also know, they dont like talking about it with the general public.

Wait a second.
Do you admit that there were major solar flares recorded during Apollo missions?
And for the sake of our discussion, Apollo 13, while the astronauts were sitting in the LM?
It would have to radiate its heat away before it would become cool enough to turn back into ice. But as a gas in a vacuum, it would spread over a very large area very quickly.

Well wouldn't crystallize in space?
Do you have a source for the claim that the electronics contributed a negligible amount to the heat radiated by the cooling system?

NASA claims the heat from the electronics was negligible.
Plus, the LM was turned on, otherwise how were they communicating?
How were they steering the ship?

Note the location of the flares, N10 W50 for the first flare. The second flare was at N15 W85.
Let's look at where those are on the sun:
N10 W50:
N15 W85:
Both happened near the edge of the sun. Since the particle flow is directed perpendicular to the surface of the sun, the particles from these events posed no threat to Earth, and hence, the astronauts.

Yes, the LM was turned on. Hence, the LM was warmer. The CM was turned off, and it was much colder than the LM.

Yes, the electromagnetic radiation hit earth. This is much less dangerous than particle radiation.

Well Nat something managed to hit the Earth because there was a SID measured.
Are SIDs not dangerous outside of the Magnetosphere?
The whole idea of insulating the spacecraft is to keep the heat of the sun out. The side effect of that is it bottles in any heat generated inside the craft, so the thermal systems must be able to get rid of that.

No, I was doing it from memory.
I could be wrong, but I thought I read that the heat from the electronics was negligible, probably in comparison to the sun.

Ok, but the PLSS were covered.
What exactly occurred under those coverings?
The liquid transport loop (fig. 36) is the primary means of thermal control of the crewman. Water from the LCG enters the loop through the multiple water connector and passes into a gas separator, where a 400-mesh semipermeable screen traps any free gas in the water to avoid cavitation in the pump. Excess separated gas can be bled through a manually operated gas bleed port. From the gas separator, the water flows to the pump motor assembly, which creates a minimum pressure rise of 18. 5 kN/m^2 (2.68 psi). The pump forces water through the transport water loop at a minimum flow rate of 1.72 kg/min (3.8 lb/min). In the sublimator, heat is transferred by the heat exchanger fins from the liquid transport loop to the feedwater loop. After passing through the sublimator, the cooled water circulates around the fan motor to cool the motor electronics. A check valve located between the feedwater loop and the liquid transport loop maintains a constant operating pressure on the pump. The coolant flow rate through the sublimator is regulated by the PLSS water diverter valve, which, in the minimum position, diverts the flow, allowing most of the water to bypass the sublimator before returning to the LCG. In the maximum valve position, all transport water flows through the sublimator; the intermediate position is a midpoint between the two extremes. The temperature difference between the water entering and leaving the water transport loop is sensed by a differential temperature transducer, and the output signal is telemetered. The actual temperature of the water leaving the PLSS is sensed by the LCG inlet temperature sensor and is carried on telemetry. The cooled water is finally returned to the LCG through the multiple water connector.
With the change to higher metabolic loads and the water-cooled concept, it was decided to change from the water boiler concept to the sublimator to take advantage of its improved performance. Developmental work on this new type of space heat exchanger had shown improvements over the water boiler of approximately 30 percent in heat rejection per 0. 45 kilogram (1 pound) of equipment and approximately 40 percent in heat rejection per unit of volume. As designed for the PLSS, the sublimator (fig. 45) contains flow paths for both the ventilating gas and the transport water. Adjacent to the plates that form the walls of these passages are sintered nickel plates having
micrometer-size pores. One side of the porous plate is exposed to vacuum; the cavity between the other side of the porous plate and the transport fluid passage plate is filled with water under slight pressure. The slight pressurization is derived from the internal suit pressure. This "feedwater" is carried in a reservoir in sufficient quantity to satisfy all heat rejection requirements. As the feedwater exudes through the pores of the sintered plate, it freezes on the vacuum side and forms, in effect, a seal against feedwater loss. Heat transferred from the gas path or from the transport water path is carried through fins and through the feedwater to the porous metal plate. The rate of sublimation of the ice formed on the porous plate is a direct function of the amount of heat carried to the sublimator by the transport fluids. Entirely self- regulating, this system requires no valving to control the amount of feedwater admitted to the sublimator section, nor does it require a temperature- sensitive or pressure-sensitive valve to maintain a controlled pressure in the boiling chamber for temperature control.

RIGHT and how can they do that with all the equipment shut down.????

I'm saying I can't adequately comprehend the evidence you've presented in order to make a claim one way or another.

So I gave you evidence, you still want to deny a major solar flare occurred during Apollo?
