Through noon - conditions were tough to see any convection or blips but floating surface bubbles came thru Little Whirligig at intervals so it appears it was rising and dropping a bit - water coming in from above seems reduced from No Porcelain area i crater rim above the ramp is still green |

Overflowing and bubbling on arrival. Black streamers are growing below Little Whirligig that were not there last year. Runoff is entering the pool from two different spots, and the center of the pool frequently convects. Water color and clarity is similar to Whirligig, murky teal. No bubbling or change in overflow during my sit after the arrival bubbles. "Constant is not very constant" quote tally is 4. |

in overflow - tiny blips some which looked promising but too windy and steamy to tell if they were periodic on a "schedule" or to discern if pool slightly dropped after the better ones - water entering the pool from elsewhere in two places |

There are 4 active bubblers in Constant's main runoff channel that flows past the living thermometer sign. 1st one from the pool is in the narrow neck of the channel, oblong in shape, 2" long and bubbling to 1". Other 3 are in the middle of the wide area, 1st of these vents from Constants pool is 2" in diameter and blipping to 2". Other 2 are smaller in diameter with a 1/2" bubble. There is a active Frying pan type sizzler between the runoff channel and the Constant bench, about 1' from the edge of the water in the dry pebbly area, that cycles water and sizzles/flashes. |

arrived 0840 to a full pool - small blips with minuscule waves was the biggest action - as far as I could tell it never dropped after the mini pushes continuing to lightly flow thru Little Whirligig and more runoff in the other channel SE - pool was unchanged upon return from breaks - 10hrs+ with no eruption |

except for a brief break I had eyes on Constant which did not erupt from 0900 to 1635. Upon returning from break pool level looked the same - no noticeable pushes w no eruption and the typical drop just ever so subtle drops - very windy and lighting was bad so it was difficult to watch overflow but it did vary |

FYI. Constant has not put out pushes/overflow that reaches the monitor minutes before the eruption all day like it was earlier this spring. |
