Springtime STEVE Sightings


STEVE ( Strong Thermal Emission Velocity Enhancement ) might look like an aurora, but it’s not. STEVE is an atmospheric phenomenon characteristic of northern hemisphere spring and fall. The result of uppity solar wind messing with Earth’s magnetic field. Meddling which allows ribbons of super heated gas travelling at speeds exceeding 13,000 mph to create observable arcs of soft purple hues. STEVE favours latitudes between +50N and +55N. Go STEVE! Hope to meet you one day.

Planet Of The Apes….


A fight between rival gangs of monkeys in Lopburi Province, Thailand delivered another  global pandemic reality. In the pre-COVID-19 world, throngs of monkey feeding tourists kept peace between city and temple simians separated by a railroad track. Gang warfare driven by starvation ensues when absence of tourists obliterate their primary food source. A local shopkeeper captured this brawl over a single piece of food. –

Time To Buckle Down


This time last week it was business as usual, tonight I’m applying for unemployment insurance benefits. Cheerful optimism fell laughably short of calculating the impact of COVID-19 on my livelihood. Corporate client cancellations started trickling in seven days ago. Come Wednesday a swanky event at Science World cancelled with less than 24 hours notice. The following day cancellation notice came moments before guest arrival. Seems coronavirus concerns outweighed $12,000 invoice for calling it quits on the spot. I sent staff home with assurance they’d be paid for time and inconvenience. Yesterday, end of business concluded with notice all venues, universities, conferences and corporate meetings were cancelled until April 30th. As of yesterday I’m a hospitality causality of COVID-19.

Time to buckle down. Went shopping today, grocery store shelves were stripped of canned goods, meat, frozen vegetables, bread and cold/flu medication. Being a workaholic I’ll need time to adjust. On the upside my kitchen needs a fresh coat of paint – looks like I’ll have time to polish my nest.

Turn That Rainbow Upside Down


Don’t know about you, but I’d be rubbing my eyes if a upside down rainbow crossed my path. Who knew? Seems weather phenomena has an arsenal of tricks up her sleeve. Technically, upside down doesn’t qualify as rainbow. They’re known as circumzenithal arc or CZA, elite members of the halo family. Whereas rainbows form when light (most commonly sunlight, sometimes bright moonlight ) passes through low atmosphere water droplets, CZA require atmospheric ice crystals and just the right degree of sunlight.

A rainbow-like arc in the sky, with red on the bottom of the arc, behind a tree.

David Lamberti caught this circumzenithal arc in 2019. Notice the kite in the tree! He wrote: “It was a beautiful January day in southeast Michigan. I looked up, and there it was, a beautiful circumzenithal arc. It was enormous, and the colors were very deep. It faded within 5 minutes.” From – https://earthsky.org/earth/i-saw-an-upside-down-rainbow-circumzenithal-arc?utm_source=EarthSky+News&utm_campaign=2be56154d1-EMAIL_CAMPAIGN_2018_02_02_COPY_01&utm_medium=email&utm_term=0_c643945d79-2be56154d1-393970565
