This is a spare satellite or its status is unknown. Brightness estimate may be unreliable and flare time accurate to a few seconds.

Imaged the Sun this morning when clear spells occured. With Lunt35 and DMK41. Was imaging in hiding tent and did not noticed it was snowing. So only a few minutes observation/imaging and rushing back in ... See below.
February 21, 1938 George Ellery Hale died in Pasadena. Principally he was an astrophysicist and he distinguished himself in the study of solar spectra and sunspots. He developed a number of important instruments for the study of solar and stellar spectra, including the spectroheliograph and the spectrahelioscope. Ten years after his death, his greatest dream, the 200 inch reflecting telescope on Mount Palomar was completed. Born in Chicago June 29, 1868.
