چکیده
We present spectroscopy of the coma center comet C/2020 F3 (NEOWISE), carried out at end July 2020 with \'Echelle spectrograph FLECHAS University Observatory Jena. The was observed in 5 nights and many prominent emission features were detected between 4685\r{A} 7376\r{A}. Beside C$_2$ Swan bands also several amidogen radical, as well two forbidden lines oxygen identified spectra all observing epochs. In contrast, strong sodium only comet, taken on 21 23 2020, which significantly faded these nights, no longer 29 2020. this paper we characterize most features, discuss their variability throughout our spectroscopic monitoring campaign, use them to derive radial velocity nights.

NEOWISE observations of comet C / 2013 A 1 ( Siding Spring ) as it approaches Mars
The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission observed comet C/2013 A1 (Siding Spring) three times at 3.4 μm and 4.6 μm as the comet approached Mars in 2014. The comet is an extremely interesting target since its close approach to Mars in late 2014 will be observed by various spacecraft in-situ. The observations were taken in 2014 Jan., Jul. and Sep. when the comet...

Calculations further support the premise that large-scale synchronous firings of neurons may affect molecular processes. The context is scalp electroencephalography (EEG) during short-term memory (STM) tasks. The mechanism considered is Π = p + qA (SI units) coupling, where p is the momenta of free Ca waves q the charge of Ca in units of the electron charge, and A the magnetic vector potential ...
متن کاملFiber-optic Array Spectroscopy of NH2 In Comet Hale-Bopp: Nature of the rotational energy distributions
Moderate resolution spectra of the 030 band of NH2 near 6300 Å were recorded in Comet Hale-Bopp near 2.6 and 1.0 AU with the HYDRA array spectrometer on the WIYN telescope. The spectra from beyond the collision sphere were examined with respect to the relative rotational energy distributions in NH2. The relative rotational profiles could be consistently fit at both heliocentric positions by a p...
