    Summary Author: Giovanni Tumino

    During one of the numerous paroxysms of Mt Etna (Sicily, Italy), I
    decided to spend the night filming the lava flow it generated. This
    flow emanated from a new eruptive mouth that opened at
    approximately the 2,800 m (9,186 ft) level on May 29, 2022. Though
    these flows look ominous, fortunately the Bove Valley acts as a
    container for the lava flow that would otherwise pour over the Etnean
    towns. Photos taken on June 2, 2022.

    Cumulus Clouds with Spikes

    Summary Author: Mila Zinkova; Jim Foster

    Shown above are curious shaped, cumulus clouds that were observed
    from near my home in San Francisco, California, on April 19, 2022. The
    spike-like features have horseshoe shapes in some cases, as shown in
    the bottom photo. Perhaps these spikes and horseshoes are caused by
    convection -- intense localized heating of the most optically
    thick portion of cloud by the strong April sun. However, because the
    atmospheric environment where the clouds formed wasn't suitable
    ( stable atmosphere) for widespread building, they remained overall
    fairly “flat” in appearance. Click here to see a video of these
    clouds.
