Expanded Owens Valley Solar Array

The Expanded Owens Vally Solar Array is a telescope facility operated by NJIT. Observes the Sun in microwave wavelengths.

New Nature paper by Fleishman et al unravels the efficient acceleration region for high-energy electrons in a large solar flare, using microwave imaging spectroscopy data taken by yours truly ⁦@NJIT⁩ ⁦@CSLANJIT⁩ #NSF_funded https://t.co/jR35xy0AHm

EOVSA just bagged a broadband solar microwave emission ~ @ 16:45 UT 👇.

☝️👇Now, VOILA! -- Here is the broadband microwave emission rolling off a hot EOVSA press. 👍🌞👊

Compare the yellow marks on the EOVSA spectrogram with what you see on solar images, & GOES x-ray flux, & D-RAP & other data sources & tools you're using.

EOVSA loved a little solar rollercoaster ride we just took between 20:35 - 22:35 UT. Speedbumps! Here is EOVSA's microwave response to series of GOES x-ray bumps that just happened, producing an M1.13-class x-ray peak @ 22:02 UT over Hawaiian Islands.

Great to hear! Grateful for the efforts of the first responders and the OVRO staff! We sincerely hope the other OVRO facilities are okay, too.

[Morgan Catha @MorganCatha]

@EOVSANJIT EOVSA is ok but power will be out until DWP can repair our power line.

[Expanded Owens Valley Solar Array @EOVSANJIT]

Hope everything is okay 🤞

@EOVSANJIT #AirportFire caused a mandatory evacuation of the observatory as well as East Big Pine. The site is without power so we won’t know much until people can check this morning.

[Dr. Bin Chen @BinChenNJIT]

New paper alert! In this study led by our grad student, Yuqian Wei, we use microwave imaging spectroscopy from @NJIT's EOVSA (@EOVSANJIT) to measure the coronal magnetic field along an active filament, which erupted after the 2017 Sept 6 X9.3 mega-flare. https://t.co/Tfyd1LXroK

[Paulo Simões, PhD @pjasimoes]

New paper alert! A solar flare driven by thermal conduction observed in mid-infrared, led by Fernando López. Happy with this analysis of IR and E-OVSA data. Soon in @AandA_journal

Our results are highlighted by Mike Wiltberger of NSF's Geospace Section in his agency talk at the (virtual) AAS/Solar Physics Division meeting. Published recently in @NatureAstronomy: https://t.co/8SVXH0cXP1 NSF Research News: https://t.co/UW4i4K7Vi6 #spd51 #NSFFunded

[Expanded Owens Valley Solar Array @EOVSANJIT]

We are delighted to share that our new @NatureAstronomy paper https://t.co/8SVXH0cXP1, based on observations from #EOVSA & #NASA spacecraft & numerical simulations, is featured by @NSF on its front page. @NJIT @CSLANJIT @CenterForAstro #NSFfunded https://t.co/UW4i4K7Vi6

[ARCHIVED - NASA Sun & Space @NASASun]

.@NJIT & @NASA data gave scientists a new look at the central engine of a solar flare. Combined with @CenterforAstro simulations, the data revealed more about the magnetic fields & energetic particles at the heart of such solar explosions. More from NJIT: https://t.co/vUsjsK473z

[Dr. Bin Chen @BinChenNJIT]

Pleased to share another of our latest works on this beautiful solar flare (see our earlier paper https://t.co/MlRswhPeXI on the accompanying eruption). Here we focus on its "central engine". @NJIT story: https://t.co/USzXTzYF9M. @CenterForAstro story: https://t.co/vUUffDVovw

#EOVSA observed in microwaves the same flare reported today by the Solar Orbiter X-ray Spectrometer/Telescope (STIX) team. The microwaves show the presence of high energy electrons. Compare the time profiles! #SolarOrbiter #TheSunUpClose @stix_so

[Expanded Owens Valley Solar Array @EOVSANJIT]

#EOVSA can be used to image quiet-Sun features. Images taken on 2020 June 23 show a filament channel, which exhibits in microwave wavelengths as a dark feature due to free-free absorption. Traces of the same filament channel can be seen in H𝛼 and extreme ultraviolet images.
