Great to be part of this!

OVSA for spaceweather! (my poster to be presented next week at Spaceweather workshop

Update to the OVRO-LWA real-time solar radio spectrum live website. I integrated GEMINI from @GoogleAIStudio to look at the spectrum and report what's happening. @EOVSANJIT ovsa.njit.edu/live/

A new Special Issue opens for submission! Title: Symmetry/Asymmetry in #SolarPhysics: Latest Advances and Prospects Editor: Peijin Zhang and Zesen Huang Details: brnw.ch/21wZBzE #callforpapers #mdpisymmetry #solareruptions #plasmaphysics @NJIT @UCLA @MdpiPhysci

Thrilled to share: I’ve been awarded $5,000 in Google Cloud Compute credits from @googlecloud ! ☁️🚀 I’ll use it to validate the scalability of LWA solar radio imaging processing pipeline—pushing throughput & distributed processing at scale. #GoogleCloud #Scalability #HPC

[Milestone] OVROLWA solar obs produces over 100 million images of the Sun! Realtime pipeline generating 144 fine-channel images every 20 seconds to track solar bursts, flares, and CMEs. #SolarPhysics #SpaceWeather #OVROLWA #RadioAstronomy #Heliophysics #OpenData #NJIT

OVRO, here I am, again

Call for Papers – Special Issue in Symmetry Symmetry/Asymmetry in Solar Physics: Latest Advances and Prospects mdpi.com/journal/symmet…

#AGU2025 Hi everyone! I’m giving a talk on real-time solar & heliospheric diagnostics with OVRO-LWA. Please stop by and take a look at. 🕘 Friday (Dec-19) 9:00 AM | room 288

Now I have one LWA antenna, I just need another 351 LWA antennas to build an OVRO LWA

@Magnetodawn @BinChenNJIT @MorganCatha @EOVSANJIT configuration test, now it's back to normal

Psychedelic! @peijin94 @BinChenNJIT @MorganCatha @EOVSANJIT

Paper published: doi.org/10.1051/0004-6… by @pietrozucca Beautiful observation with @LOFAR . A CME with multiple particle acceleration sites, indicated by multiple bright spots around the shock front.

@MorganCatha @Magnetodawn @BinChenNJIT @EOVSANJIT That's very important work! Thank you for your hard work so we can have a stable data inflow. I know nothing about hardware; it's like a black box for me. I only work with the data.

@Magnetodawn @peijin94 @BinChenNJIT @EOVSANJIT I'm definitely no mastermind, but I was in charge of building out the expansion, and I did a lot of repair work on the existing antennas and improvements to reliability for the array

@peijin94 @Magnetodawn @BinChenNJIT @EOVSANJIT When did this collaboration begin? When I was building the LWA expansion a few years ago, I dont recall NJIT being involved in any substantial way.

@MorganCatha @Magnetodawn @BinChenNJIT @EOVSANJIT Imaging with 10s cadence has 352 full set working, beamform for solar beam only uses the core set (256) for a larger beam-size to cover the whole Sun

@peijin94 @Magnetodawn @BinChenNJIT @EOVSANJIT Why only 256?

@MorganCatha @Magnetodawn @BinChenNJIT @EOVSANJIT Mostly data processing

@MorganCatha @Magnetodawn @BinChenNJIT @EOVSANJIT It's a collaboration. Caltech operates the instrument, NJIT CSTR team operates the solar observation and research of OVRO-LWA.

@Magnetodawn @peijin94 @BinChenNJIT @EOVSANJIT Also why is this display being provided by NJIT and not Caltech?

@MorganCatha @Magnetodawn @BinChenNJIT @EOVSANJIT Beamform mode almost always 256 ant

@Magnetodawn @peijin94 @BinChenNJIT @EOVSANJIT Do you have visibility to how many antennas are online at a given time?

@Magnetodawn @BinChenNJIT @EOVSANJIT @MorganCatha Currently testing new ML models for event detection, boxes can be off sometimes

@peijin94 @BinChenNJIT @EOVSANJIT @MorganCatha Thank you, Peijin. That is what I presumed. But it is always good to know what is happening, at the business end, and in the computing brain. Congratulations on getting thru a tricky day with flying colors!
