Tonight we had great weather: low winds, moderate humidity, good seeing (0.6”–0.8”), and spent the whole night from civil dusk to civil dawn on bright stars near zenith! We stuck with the IR WFS and did calibrations and noise measurements all night long. For example, here is a Hadamard Matrix measurement using CACAO to look ...

Tonight felt a lot like whiplash, from tired to energized to tired to energized, from starry to humidity to starry, and from failure to fix to failure to fix!
First of all the MAPS daytime/nighttime/whenevertime support crew (Oli, Grant, Dan) drove up this afternoon with the repaired (by Ken) bias board for the CCID-75 LittleJoe controller, ...

As a current resident of Arizona and a former resident of New Mexico, part of me must celebrate when water falls from the sky in these drought-stricken drylands or deserts. As an astroengineer and astrophysicist, it does make observing …difficult. Either way, it’s still beautiful:

What’s this, another MAPS run? Yup, the moon is almost full, and here we are again!
Unfortunately tonight we are 0 for 5 on AO engineering/commissioning productivity. Here are the 5 things:
Can we safely open the dome? No, the humidity is so high that condensation could ruin all the sensitive equipment.
Can we safely expose the ASM ...

The full moon is waning and that’s a wrap on the first MAPS run of 2023B! We have 3 more runs, on the full moons in October, November, and January.
On this run we successfully closed the loop with our new software algorithms, which required taking new timing data and calibrations. We also got offloading within ...

Dear readers, we have no science news to report. It has been windy and has stayed windy, with a fresh splash of humid to boot. So unfortunately, we do not have new science content to report. The experts have already shared their knowledge of some of the instrument’s background so tonight we’ll take the ...

As was stated in the Mary Poppins Movie “Winds in the east, mist coming in, /Like somethin’ is brewin’ and bout to begin. /Can’t put me finger on what lies in store, /But I fear what’s to happen all happened before.”
For us it has been out of the South with max of 60 ...

Tonight is our first *official* night on the telescope schedule, as last night was originally scheduled as an MMTO M&E night (maintenance and engineering) that the telescope ended up not needing more than we did, so they let us have an extra night to focus on our alignment. Thank you MMTO!
Craig and Dan came back ...

Hello Extreme Wavefront friends, I’m back! Tonight was the start of our first MAPS run after the summer shutdown and it’s the usual packed control room, multi-tasking team, full moon, and beautiful mountaintop observatory!

Manny caught an unsuspecting grad student sunset-watching.
Well, the fun had to end sometime. This post marks the official end of the MAPS 2023A run, after a weather-ful last two nights.
One of the big perks of mountain observing in AZ, especially in June, is replacing the 100ºF highs of the valley with mountain temperatures of ...
