With a busy week on the Sun likely upcoming, it's important to get your #SpaceWeather news from trusted scientists/forecasters in the field! I recommend following: Vincent Ledvina, Halo CME, ☀️ Sara Housseal ☀️, Scott McIntosh, Dr. Tamitha Skov, Dr. C. Alex Young, Space Weather Watch, Carina ☀️ Alden, (and me).

Impressive development of AR 4197 (former 4170) over the past 24 hrs. It is adding a lot of umbral and penumbral area, the central part of the AR looks quite impressive with strong polarity mixing. It has been a while since we have seen development this vigorous. Looks promising.

Safe to say, Jim Tang approved of the haboob #azwx

AR 4197 currently possesses a "delta spot" - an area where positive- and negative-polarity umbrae are within the same penumbra. This is sometimes called a "magnetic knot" in sunspots. You can see the delta spot indicated in this screenshot which I have annotated. This is the

I genuinely could not be more excited for the approaching sunspots on the limb of the sun. Like, the anticipation for a big solar storm is real. I need more space lights. My mind is on two things right now. Soon-to-be fall colors and potential coming Aurora. Can we be so lucky?

Time-lapse footage of the MASSIVE HABOOB that swallowed Phoenix this evening!!!! #azwx #haboob youtube.com/watch?v=VySJEd…

One more shot off the drone of the massive haboob about to swallow a mountain and the city of Sacaton, AZ #AZwx

Like, my goodness, please, I beg of you.

This goes unbelievably hard

Death Valley put on a show for the ages. Probably my favorite lightning shot ever in Badwater Basin tonight. #cawx

M3.5 flare and climbing coming out of the SE sunspot cluster. I wouldn't be surprised if this produces a large CME. Still early, but unlikely Earth-directed due to it still being just over our side of the limb.

Beautiful M4.5 flare and eruption off the SE limb.

If you've seen the optimism on the platform about the potential for solar weather at Earth, it's due to large Sunspot clusters on the limb or on the opposite side of the Sun. As the sun rotates, these regions come into view, and the center disk region where Earth and the Sun

Love's forecast discussion: WATCH #1964: There's a 100% chance of a new Love's in the highlighted area. Can anyone guess where? #wx

It is now that time of year where we start to fill in the map with exceptional desert lightning and Haboobs!

Very deep tropical airmass over (you guessed it!) Phoenix, AZ, this morning. PWats reaching 1.79" of water, appreciable elevated instability in reserve, and a nearly saturated profile with the surface at 77/70 means heavy flooding chances and precip-loaded thunderstorm downdrafts

Hate to be that guy, but AR 4197 is not looking as healthy as it was 24 hours ago... it is still a threat for M-class flares... but it lost a little of that "angry" look it had last night... let's see, though!

Been having a lot of people ask about it so they shall receive! Full drone video encounter of the haboob across Phoenix yesterday below! #AZwx youtu.be/4cV3eSvMhzI

Once again, robbed in Lone Tree from any precip. Brutal! #cowx

Someone grab a defib unit, the Sun has flatlined.
