The aurora of March 23,2023,caught early in the evening when there was a green arc to the south as the sky darkened that exhibited a "dunes" type of structure,with horizontal banding rather than vertical rays or curtains. Above is a purple arct that has some characteristics of a STEVE arc but is likely a standard vertical curtain. At right are Venus and the crescent Moon below,above the glow of twilight. Orion is left of centre,with Sirius embedded in the dunes arc. This is looking southwest to west. The time was about 9 pm MDT.

13999716 - Venus in a close conjunction with dimmer Saturn in the evening twilight on January 22,2023. They were 22 arc minutes apart this evening. The 1-day-old waxing crescent Moon is below the planet pair deep in the twilight. The magnitude 2.8 star Deneb Algiedi,aka Delta Capricorni,is faintly visible below Venus. Venus was magnitude -3.9 while Saturn was magnitude 0.8.

An ice crystal halo around the waxing gibbous Moon set in the winter stars of a January night. The 22° halo is most obvious and with a reddish and sharper inner rim.,and a bluish and more diffuse outer edge. But a faint inner 8° halo is also visible,a rare halo sometimes called the Van Buijsen Halo (according to Lynch and Livingston in their book Color and Light in Nature; Minnaert also mentions it in his seminal book The Nature of Color and Light in the Open Air). It is not a lens flare as shots taken with the Moon well off to one side of the frame still show the inner halo centred on the Moo
