Here's a timelapse of images over 2.5 hr from May from of the supermassive black hole Sgr A*. The black hole is always variable, but this was the brightest we've seen in the infrared so far. It was probably even brighter before we started observing that night!

Amazing. Thanks for sharing.

It's amazing what can do! I will be very happy when we get back on sky. I'm desperate to know what is going on with Sgr A* right now!

So the Moon just went (relatively) near Sgr A* in the sky, and I presume that's what's limiting ground based observations. Did anyone try and get Spitzer / SIRTF time for this bright sky period?

No, in our case, it’s the lack of access to any of the telescopes on Maunakea. For IR observations, sky brightness is far less impactful.

We can still get data from Keck for a few more weeks before the Galactic center is no longer observable until next year. There are a other telescopes including Spitzer, Swift, Chandra, and ALMA that has been observing Sgr A* this summer and I'm eagerly awaiting their results!

How can we see the galactic center if we’re on an outer arm? Are we ...under... the center looking up at it?

But in the radio (mm and cm) or the IR or the X-ray the dust is transparent, and those telescopes can see Sgr A* _through_ all the stars and dust.
