Thank you all ! Found another silver lining,,well, silver spots, in the B&W category.
Congestus On The Rise
Yes Keelin, hence the olde saying,, every dark cloud etc…Much like Hope. It took me a while but I finally found an appropriate shot, I think.
Well heck!…This afternoon I noticed the clouds where A) low cumulus B) coming down from the north north east rather than from the normal west. C) Winds at cloud level , 3kft to 5ft+, appeared rather strong, bending cloud tops over in wave form..D) one area of the sky just north and east of me, appeared rather turbulent. So ..i kept my eyes open. With a little patience, maybe 30 minutes of lawn and gardening, there it was. A large one, well a close one, a classic horseshoe in the sky just about center of the earlier turbulent area.How strange I thought as I took a pic or two, just posting about these at CAS. It lasted for over 2 minutes. I didn’t see it evaporate due to a lower cloud swept under it hiding its demise from me. Once again when weather comes from a rare direction expect a rare spotting!
Aaaahh Duplicatus Lacunosus…Cool stuff Hans!
Heres some “experimental” dupicatus also. The “white” is actually higher altostratus.

Eric, I can’t say I’ve seen a HV from the very beginning. I have seen one or two evolve from slightly bent to full arms to wobbly ribbon of flapping then to gone, dissipated back from which it came. But most have been full horseshoe by the time I recognize them.I’ve kept an eye for them especially when there is fast moving layers of cloud. I’ve noticed HV tend to occur on the edges of active clouds as in contorted or undulating etc. Its like looking for pileus. One learns when conditions are right and where to look for just a smudge signalling the beginning. And yes..I’ve learned don’t take the camera away until its over. The Gallery would make it seem HV are common until you look at the dates of the Pictures. There are cloudspotters who have never seen one.
Congrats epshulz! The HV is amazing to witness. I’ve seen a few. But..what makes them.. is invisible according to the latest..Imagine a roller of air..horizontal..a column of air rolling along horizontally. The ” cloud” that we call a horizontal vortex,,is created at the top of the rolling air column and eventually the ends of it drop forming the downward arms creating the Horseshoe appearance, or upside down U. The column of horizontal air may last awhile or not. I’ve seen vortexes that last a 5 minutes and some that lasted 30 to 45 seconds.
George , yes , it was an asperitas event. In there was this flat bottomed cloud and the light became right so became the picture. Asperitas means mixed up or stirred or asperated . That event became chaotic in that area of the sky. A undisturbed cumulus in the middle of it all seemed odd.
