Observations for 2018 September 12
Another time that we'd planned for an early trip to Norris, only to wake up and discover there's no need to go. In this case, the eruption of New Crater/Steamboat was either too late or too early. Too late in that there's no way we'd have spent over eight hours in the dark waiting for it. Too early because it erupted before we even had a chance to hit the road.
So it was a day to start watching Giant, even though the four day mark wasn't until near sunset. Got to see a fairly strong hot period around 10:30, then over seven hours later there was a fairly weak one with only Feather and its Satellite.
After dark, four hours later, we pretty much got the same hot period. With it supposed to be wet, I wasn't going to be out in the dark.
