IntroductionThe Astronomical League has identified opportunities to commemorate special astronomical events and bring you AL Observing Challenges. New opportunities will be added as significant celestial events are identified. |
Requirements and RulesTo earn the certification, you need to meet these requirements:
You do not need to be a member of the Astronomical League to receive the first level of this certification, but it is required for the second level. If you are not a member and would like to become one, check with your local astronomical society, search for a local society on the Astronomical League Website, or join as a Member-At-Large in the member at large . |

The AL Observing Challenges
Current Challenges:
10. T Coronae Borealis Observing Challenge and Special Observing Award. (deadline for submission will be one month after the eruption)
Effective immediately, the Astronomical League is bringing you another Observing Challenge. This one is for the pending eruption of the Nova T Coronae Borealis. it is expected to happen some time between now and September. There will be two levels of this award, both will include certificates and Level 2 will include a pin.
Levels and their requirements:
Level 1 – AL Observing Challenge. (certificate only)
- This level may be done by anyone, even non-members of the Astronomical League.
- This may be done visually through a telescope or through imaging.
- Two observations are required:
- Observe T Coronae Borealis before the eruption (now).
- Observe T Coronae Borealis during the Nova stage.
- An Outreach Activity is also required, to share this event with the public.
Level 2 – AL Special Observing Award. (certificate and pin)
- This level requires membership in the Astronomical League.
- The brightness data (measurements from your observations) must also be submitted to the American Association of Variable Star Observers.
- Their website: https://www.aavso.org/
- You must have an account and an ID with AAVSO to submit. You do NOT have to join AAVSO to submit.
- This is much more valuable (and accurate) if you are doing this through imaging.
- We encourage you you to also use a photometric “V” filter if possible.
- All instructions and information on submitting data is on the AAVSO website. They have manuals to help you with the process (https://www.aavso.org/observing-manuals.):
- Visual observers should use the “Manual for Visual Observing of Variable Stars”
- Monochrome CCD/CMOS images should read the “Guide to CCD/CMOS Photometry with Monochrome Cameras” and
- Folks with color cameras, including DSLRs should go to the “DSLR Observing Manual”.
- You should make the first observation as soon as you can, before T Coronae Borealis erupts, even if you are not yet set up to submit data to the AAVSO. The important piece is to collect the data now.
- This is the same process that is used in the Astronomical League’s Variable Star and Nova Observing Programs.
11. Solar Maximum Observing Challenge. (deadline for submission is April 30, 2025)
Effective immediately, the Astronomical League is bringing you another Observing Challenge. This Challenge is to experience the Solar Maximum. There will be one level of this award and recognition is in the form of a certificate. You do not need to be a member of the Astronomical League to participate in this challenge and to receive the certificate. Although no telescopes of binoculars are required for this award, you will need to build an inexpensive homemade magnetometer. Note: For Astronomical League members, these Observations may be used and submitted as part of the Space Weather Observing Program.
Submission Requirements:
- Build a soda bottle magnetometer.
- Instructions can be found here: https://www.astroleague.org/wp-content/uploads/2024/09/Soda-Bottle-Magnetometer-2.pdf
- Materials needed are:
- An empty 2-litre soda bottle.
- A couple inches of ballast (sand or small pebbles) to keep the bottle stable.
- A small lightweight mirror.
- A small bar magnet. One to two inches long to fit inside the bottle.
- A drinking straw.
- Thread.
- A small index card.
- A yard stick or a meter stick.
- A white flat target.
- A light source (a faint red laser works well).
- Use that magnetometer to detect variations in the Earth’s Magnetic Field.
- Do a minimum of 50 observations.
- Note: this can be done inside and even in bad weather.
- Challenges we have noted with the Magnetometers can be found here: https://www.astroleague.org/wp-content/uploads/2024/09/Magnetometers-Challenges.pdf
- You may start immediately but must finish them by March 31, 2025.
- You may do up to two observations daily, ideally about 12 hours apart.
- The magnetometer must be somewhere where it will not be disturbed.
- Note: we have received some feedback that it is critical to place the magnetometer and the laser on a very solid surface. If not, the spot (and the mirror) move due to vibrations.
- In your observation log, note the location along the yard stick or meter stick where the reflected laser spot is located.
- Compare your observed activity with observations from NASA.
- NASA data for the Planetary K-Index can be found on this web page: https://www.swpc.noaa.gov/products/planetary-k-index.
- Include copies of the column charts in your observation logs.
- Note sunspot activity on the Sun.
- A good source for this is: https://www.spaceweather.com/.
- Click on the image of the Sun on the left side of the web page to see more detail. Include copies of these images in your observation log.
- Information on individual solar flares and active regions on the sun can be found here: https://www.spaceweatherlive.com/en/solar-activity/solar-flares.html.
- Predict expected auroral activity in the Earth’s Atmosphere.
- Light reaches the Earth from the Sun in a little more than 8.33 minutes.
- Charged Particles in the solar wind (space weather) travel slower. Charged Particles in the solar wind travel from 250 to 750 km/second, or roughly 560,000 miles/hour to over 1,675,000 miles per hour.
- The Sun is roughly 93 million miles (149 million kilometers) from the Earth.
- This means that charged particles will reach Earth some time between 55.5 to 166 hours or between 2.3 and 6.9 days.
- Compare your prediction with actual activity. (Personal observations of the Aurora are not required, but certainly would add a level of excitement to those who can see them.)
- Auroral activity can be seen on the same page as the sunspot activity: https://www.spaceweather.com/.
- Scroll down to the current auroral activity map. Default is for the northern hemisphere, but there are alternative maps if you are observing elsewhere.
- Click on the image of the auroral map on the left side of the web page to see more detail. Include copies of these images in your observation logs.
- Do an Outreach Activity to share this event with the public.
- Observations must be done before March 31, 2025. Submissions for this award are due to the Coordinator by April 30, 2025. Late submissions will not be processed.
