Nice to see blue skies again...very quiet Sun however.

Well done.
Still clouds down here...
Did you do another exposure for the proms??

[h0ughy]

very nice even though its blank. did you change up for any proms?

[Peter Ward]

Thanks guys...I did ramp the exposure for proms, but didn't see any this morning.

That said, I did not adjust the central frequency of my filter to look for any red/blue shifted features, so maybe there is something there that I simply missed.

P.S.
Just checked Big Bear's full disk image. No proms.

Peter,
That’s interesting.
There were a few nice ones showing in GONG when I looked.

Indeed...just looked at the Learmonth data. Suspect they are doppler shifted a tad.
