| Joint USAF/NOAA Solar Geophysical Activity Report and Forecast SDF Number 20 Issued at 2200Z on 20 Jan 2022 |
| IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M5 event observed at 20/0601Z from Region 2929 (N08W88). There are currently 5 numbered sunspot regions on the disk. |
| IB. Solar Activity Forecast Solar activity is expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on day one (21 Jan) and expected to be very low with a slight chance for a C-class flare on days two and three (22 Jan, 23 Jan). |
| IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 568 km/s at 19/2117Z. Total IMF reached 5 nT at 20/0534Z. The maximum southward component of Bz reached -1 nT at 20/0839Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 22 pfu at 20/1015Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2656 pfu. |
| IIB. Geophysical Activity Forecast The geomagnetic field is expected to be at quiet to unsettled levels on day one (21 Jan) and quiet to active levels on days two and three (22 Jan, 23 Jan). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (21 Jan). |

Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA Scale levels). The greatest expected 3 hr Kp for Jan 21-Jan 23 2022 is 4 (below NOAA Scale levels).

Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No significant transient or recurrent solar wind features are forecast.
Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was above S-scale storm level thresholds.
|
Rationale: No S1 (Minor) or greater solar radiation storms are expected. No significant active region activity favorable for radiation storm production is forecast.
Radio Blackout Activity and Forecast
Radio blackouts reaching the R2 levels were observed over the past 24 hours. The largest was at Jan 20 2022 0601 UTC.
|
|||||||||||||
Rationale: No R1 (Minor) or greater radio blackouts are expected. No significant active region flare activity is forecast.

Instruments on board the NOAA Polar-orbiting Operational Environmental Satellite (POES) continually monitor the power flux carried by the protons and electrons that produce aurora in the atmosphere. SWPC has developed a technique that uses the power flux observations obtained during a single pass of the satellite over a polar region (which takes about 25 minutes) to estimate the total power deposited in an entire polar region by these auroral particles. The power input estimate is converted to an auroral activity index that ranges from 1 to 10. |

The sun is constantly monitored for sun spots and coronal mass ejections. EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. In those taken at 171 Angstrom, at 1 million degrees. 195 Angstrom images correspond to about 1.5 million Kelvin, 284 Angstrom to 2 million degrees. The hotter the temperature, the higher you look in the solar atmosphere. |

The Solar Cycle is observed by counting the frequency and placement of sunspots visible on the Sun.
Solar minimum occurred in December, 2008.
Solar maximum was expected to occur in May, 2013.

| NGC 7822 in Cepheus | |||
|
|||
2022 January 20 |
|||
Explanation: Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes stand out in this colorful telescopic skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The emission line and color combination has become well-known as the Hubble palette. The atomic emission is powered by energetic radiation from the central hot stars. Their powerful winds and radiation sculpt and erode the denser pillar shapes and clear out a characteristic cavity light-years across the center of the natal cloud. Stars could still be forming inside the pillars by gravitational collapse but as the pillars are eroded away, any forming stars will ultimately be cutoff from their reservoir of star stuff. This field of view spans about 40 light-years at the estimated distance of NGC 7822. |
