A member of the Acanthaceae family, this could be a Ruellia Simplex or Mexican Petunia, Mexican Bluebell or Britton’s Wild Petunia. It could be a Ruellia Tuberosa or Minnieroot, Fever Root, Snapdragon Root or Sheep Potato. Honestly, they look the same to me. ~Vic

“A report warns that fleets of new communication satellites in low-Earth orbit will spoil some astronomical observations, even if all known mitigation strategies are taken.”
Astronomers and the operators of new, thousands-strong […] low-orbiting satellites will have to work together to prevent them from having a devastating impact on ground-based observations of planets, stars and other celestial objects, says a [recent] report […]. Even then, there is no escaping some harm from the fleets of commercial orbiters.
“No combination of mitigation will eliminate their impact,” added astronomer Connie Walker of the U.S. National Optical-Infrared Astronomy Research Laboratory.
The satellites, designed to provide internet access in remote areas, now number in the hundreds. [Following] the launch of the first batch by SpaceX in May 2019, astronomers were alarmed by how bright they appear in the sky. If all the planned [launches] go ahead, the number of satellites will grow beyond 100,000. Since last year, there have been a number of independent studies of [satellites’] possible impact. [The] workshop’s report is the first time the satellite companies, and those who would be affected (astronomers to the agencies that fund them and their telescopes), have pooled their results and worked out a strategy for the future.
The satellite trails are very bright, and out of focus slightly, so they’re wide and cover several pixels on images taken with a test version of the (soon to open Vera C.) Rubin Observatory’s camera, notes Tyson. [Telescopes] that need to work during twilight will also run into problems. Because the satellites are in low orbits, they will often be seen close to the horizon and will be most visible when they are still in sunlight but, the observer is not. If, however, satellite operators choose orbits above 600 kilometers, the situation gets worse because, then, their spacecraft are visible for more of the night, and in [the] summer, all night long. Astronomers should also develop software tools to remove satellite trails from images and the companies should make accurate orbital data available for their orbiters so telescopes can try to avoid them.
The only measure the report could offer to totally eliminate the damage to astronomy was to launch fewer or no low-orbiting satellites…likely not an option given the financial investments the companies are making in the [satellites] and the lucrative market they foresee.
Tyson and his colleagues have been working with SpaceX engineers to modify their satellites to reduce their brightness. His team has also modeled trying to steer the Rubin Observatory telescope to avoid passing satellites but, Tyson says there are simply too many. Astronomers are already actively pursuing image processing solutions but, he says “the jury’s out” on how much that can help.

It took me a while to find this one. Even Pl@ntNet had trouble. At first, I thought it was a Coreopsis but, the petals didn’t match. Then, I thought it might be a Cosmos but, the petals still didn’t match. This is a Bidens Trichosperma. I think there has been some classification shuffling but, they are all in the Asteraceae family or Sunflower family. ~Vic

Another one of Hillsborough’s oldest homes. ~Vic
Twin Chimneys, so named for the paired chimneys in each gable end, is sited on a hill on West King Street, directly across from the Colonial Inn and the Parks-Richmond House […]. An iron gate from Stewart Iron Works in Cincinnati, Ohio, separates the house from the pedestrian traffic of the sidewalk. [It] is reputedly a pre-Revolutionary house, however, the exact date of construction is not known. It is important to note that a house is sited at the exact location on the 1768 Sauthier Map of Hillsborough but, it cannot be assumed that the houses are the same.
This is a most delightful old house, with four huge chimneys and a second-floor balcony, from which a view of the busy thoroughfare, King Street, may have been enjoyed down through the years. The lot on which it stands was once owned by Edmund Fanning.
It is interesting to know that this house was the setting for the old romantic novel, “Joscelyn Cheshire.” According to the story, the heroine concealed her lover in the attic to protect him from Cornwallis’ army. The house served at one time as Hillsborough’s Post Office.
Archibald DeBow Murphey was a North Carolina politician known as the “Father of Education” in his state for his proposals that benefited public works and public education. [Murphey] died at Twin Chimneys in Hillsborough on February 1, 1832. He is buried at the Presbyterian Church […]. The town of Murphy, North Carolina (despite its spelling) was named after him.

I’ve posted this sculpture twice, before…here & here. This will be my last installment as I only had a few shots and this shot isn’t even mine. This photo was part of a larger group of snow shots I posted about here & here.
Since it is SO HOT outside, I thought I would cool your mind a bit. ~Vic
