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.

Nice capture of winter sky Keelin. Its been cool in the desert for some days. Natures way of letting us learn patience.

Yes Hans, the wall of a towering nimbus provided gold backdrop to lower pink/red cumulus at sundown..As you know, timing is everything.
Altocumulus catches the last rays of the day..
