One of the key instruments for predicting when solar weather events will
\narrive here at Earth is the Chronograph. And one of the most widely used
\nCoronagraphs is the LASCO instrument onboard the SOHO spacecraft at
\nLagrange Point 1 (L1). This is a place where the spacecraft orbits L1 in
\na halo fashion, just like the James Webb Space Telescope at L2. The
\nadvantage of L1 is that it gets a mostly uninterrupted view of the sun.<\/p>\n

SOHO was designed for a two year mission. And here we are nearly 30
\nyears later and the spacecraft is still working. However, the solar
\npanels have degraded over that time, the gyros are no longer working,
\nand though the spacecraft has lots of fuel, it is running on borrowed time.<\/p>\n

The older LASCO C2 and C3 coronagraph images are amazing, considering
\nthat they’re 30 year old technology. Still, after 30 years we can do
\nbetter.<\/p>\n

Enter CCOR, or the Compact Coronagraph. The scientists at Naval Research
\nLab decided to see what they could do to improve on LASCO. The result
\nwas CCOR-1. CCOR-1 was launched on GOES-U which, upon arriving on
\nstation in Geostationary Orbit, became GOES 19.<\/p>\n

Since it arrived on station last July, I’ve been waiting patiently for
\nthe images from the new coronagraph to become available. It’s taken some
\ntime and it won’t be officially available until April. However, you can
\nsee what it looks like under the “experimental” instruments on NOAA’s
\nweb page.<\/p>\n

See https:\/\/www.swpc.noaa.gov\/products\/ccor-1-coronagraph-experimental<\/a><\/p>\n

Unlike the LASCO instrument onboard SOHO at L1, Geostationary orbit
\ndoesn’t offer an uninterrupted view of the sun. Often you’ll see the
\nmoon photobombing its way through the image. And there are times when
\nthe Earth may block the view of the sun. However, CCOR-1 reports
\nreliably every 15 minutes, whereas LASCO images can be delayed for many
\nhours until the SOHO spacecraft antenna points back at Earth.<\/p>\n

When the CCOR-1 data is ready for scientific use, it will become an
\nimportant backup for the aging SOHO spacecraft. Also note that NOAA is
\nplanning to launch a new replacement for SOHO at L1 called the Space
\nWeather Follow On to L1 or SWFO.<\/p>\n

Solar weather is critical for many uses, besides just shortwave radio.
\nThese include predicting degraded GPS accuracy, Satellite Operations,
\nPower Grid Operations, and in extreme cases, even alerting pilots of
\nexcessive radiation risks when flying in the vicinity of the North and
\nSouth poles.<\/p>\n

Have a look at the CCOR-1 images. It is much better at illuminating the
\ncorona of the Sun, though it does have limitations based upon where it
\nis located.<\/p>\n
