we are our friends; life will change; money mindset; 1% better each day; gym time!

i am starting to realize that life moves on, that where i live and who i live with is a unique function of my current life circumstances. and to take advantage while i can, as opposed to saving every cent. that path of least resistance will change.

in the past i used to live with very outdoors people, again by chance. i found a cheap place to stay and the people who already lived there were outdoors friends who went on trips every weekend. i could just join their trips, borrow their equipment, and all with minimal cost and energy. we also had house parties at least once a season. since we all had large social groups (e.g. my roommates belonged to big student organizations and were leaders there). i always met new people or caught up with mutual friendquaintances at these parties. semi-spontaneous trips happened even when it was freezing or raining, or required getting up at 5am or ended at 2am. the focus was on social drama and feeling pressured to be too hardcore. people often cooked and ate together or shared food.

right now, none of my roommates are very social or organizing-oriented. house parties are just my parties with people i already know. my roommate’s friends do not show up, and friends-of-friends are rare.

that was a particularly bad time of my life personally, co-founding my startup was stressful, i had no job security and didn’t know about masshealth, i was paid little, i had major self-esteem issues from MIT, i was constantly cold due to poor insulation + saving on heat, i was perpetually confused about my not-relationship, and other issues like sharing one bathroom with 5-6 people. so i don’t want to go back necessarily.

i am just more appreciative now of a time in my life that i tried to forget for many years due to the painful memories.

my roomates now are great. but half of us are over thirty, and that half has physical-mental issues of getting injured and life stresses, so the path of least resistance would be hanging out by watching tv or movies or youtube or playing video games or getting takeout. we are busy with work or school, and gone are the late nights of hacking on random extremely nerdy side projects.

is losing bits of my identity the price to pay for being happier?

for a while after undergrad time, since i grew up sheltered and well-fed, i had no sense of money and instead my only idea of budgeting was to spend as little as possible.

the idea of setting aside money to spend guilt-free on having fun each month was a revelation.

but the last few years, between taking leave without my phd stipend and living off of contract work, and then not having income and borrowing money later when I focused on writing my thesis to graduate, and then not having a job lined up, budgeting became hard again (how do i budget when i don’t know my income next month, or when i’ll next have income? how can i avoid borrowing money for as long as possible?). i reverted back to a feeling of scarcity.

now that i have some savings and some prospect of a job soon, my feeling of every dollar being an irrationally difficult decision has eased a lot. i am starting to think of rent in terms of paying to live close to my friends, and take-out as a worthwhile budget item rather than a stressful slightly guilty experience (with better planning, could I have avoided it).

i went to my pcp for my (apparently technically every two years) annual checkup. all’s well, but she mentioned looking into strength training now that i’m in my thirties.

the gym nearest to me is expensive. but i know i can go there regularly, as it’s a six minute walk and they close at 11pm. their fixed joining fee also dropped to $50 from $80. and finally, my current roommate goes to the gym 3-4x a week and has volunteered to teach me weightlifting. this seems like a very unique set of life circumstances.

so i’ve decided to try taking advantage of it! my current plan is:

https://forum.bodybuilding.com/showthread.php?t=149807833&page=1

it has been very path of least resistance. and instead of figuring out some precise workout, it’s just “do as many until it’s hard to more, then rest.” i have some sense of posture from a hand-stands class i took, so that helps.

routine has been hard. i find it hard to cut social situations short, and it’s easy to say that i’ll go later or tomorrow instead. but i’ve seen the results this week: i didn’t make it in at all. so i’ll make a conscious effort to prioritize exercise more. when something comes up, gym comes first and other stuff can wait. at least until i can build more of a habit.

i keep in mind from atomic habits: just strive for 1% better each day.

i’ve also come to understand that one day, i will get injured or frail. and i will have to try to push and work to get 1% better each day just to get back to independent living. so it is good to do this now and build confidence that all this does add up and activities that are hard now will get easier in finite time. that e.g. taking the stairs instead of the escalator is a meaningful amount of investment in myself. even if it’s not something i can brag about, or recount stories about, or i’m just plain tired. if i am unsure and on the fence about investing 1% in myself, i will default to opt-in instead of opt-out.

i think that’s all for now. i’ll have to write about my gardening and sailing another day …

aurora from rockport ma

friday night

i was super lucky to see the aurora both friday and saturday nights .

on friday night around 11pm i learned there was an aurora event from my roommate. i spent another hour finding someone to go with and then prepping (warm things). i originally planned to drive just to nahant (25 mins) since the previous night i only slept 3 hrs and i hadn’t napped that much either. (yay for 7:30am construction directly outside my window!). but i ended up driving all the way to rockport, which is the closest relatively dark place. this time i found an actual place to park (davis park) instead of a dark graveyard place.

once there we saw another person with their trunk open and a tripod out. and also a lot of people there already. and immediately we could see the aurora in the sky — it went across the entire sky. it was cool to see a sky phenomena that stretches across the entire sky. normally, stuff like the ISS or comets are just thin streaks, or even the stars or milky way. but the aurora stretched across the entire sky.

it wasn’t cool like the pictures — really just a muted green, where the sky was lit up more like dusk than the rest of the sky which was fully dark. it was bright enough to block out the stars behind it. as it faded over the hour or so we were there, the stars behind it started to peak out.

however if you took photos the aurora looked amazing.

below is a still from a video:

and the pixel phone you could actually enable astrophotography mode (enabled by default) and it would condense 4 minutes of frames down into a one-second video. basically, you have to set the phone down in “night sight” mode.

“When in astrophotography mode, Pixel phones will take 16 16-second photos when the shutter is pressed, then merge all of them together – essentially automating the work that Greszko used to do by hand.” [link]

the button changes from a moon to stars if you stop moving the phone (holding it isn’t good enough–have to actually set it down) and wait a few seconds for it to focus.

this is super compressed — some time i’ll figure out a link to the full res — so it actually looks better than this (more distinct stripes that are wavering rather than a blur).

i took all these photos without a tripod, just lying the phone on the ground or propping against a bag — i am ordering a selfie stick-tripod combo asap haha.

i was so tired on the way back i ended up napping at a charging station… i probably got back around 5:30am.

saturday

on saturday night we left at close to 11, got there ~45 mins later. was worried that clouds would come in (which there were some) and that there would not be an aurora at all. when we got there i was immediately disappointed — I didn’t see anything at all. I spent a while constantly refreshing the spaceweather website and reading up on auroras and what all the numbers meant. another friend said the peak was shifting to 5am, and planned to get up at 3am and drive two hours to maine. eventually we went to the car to warm up a bit (yay EVs, they can just heat up w/o running the engine). after a while my friend lily said “was the sky that bright before?” and i stare at it a bit too, then notice that the bright section included a stripe going upward.

after that we all tumbled out of the car to go witness the aurora. it was much smaller / dimmer than the previous night but still glorious. in a different way — specifically, it was great to share the moment with my friends and partner — and also there was a separate phenomena going on.

perhaps because of the dimness of the aurora and the underlying clouds. but it was like long lines of light racing up the sky, one after another. impossible to capture on camera since they moved so fast, unlike the aurora.

it was very cool and also a little terrifying. as if some giant creature were searching around in a dark closet with a flashlight, and we were this tiny forgotten snowglobe in the corner. i was really glad i was there with other people. unlike the previous night there were very few people there.

they were visible a bit after the aurora showed up, and stayed around long after aurora faded. so for half an hour at least.

i searched online later and never did find anything similar described online. there are pulsating auroras but those are really different. i think it wouldn’t count as an aurora at all. i’m not sure who to ask.

eventually we got tired of looking and decided to go home, since it was quite late.

i’m pretty glad i didn’t convince my friends to stay up late with me for nothing. but i do feel really bad about convincing my parents in georgia to drive up to a dark place and look for the aurora. NASA seemed convince there might be another event. i’m also sad that since i had a pixel phone and not a samsung phone, i could not help my parents do timelapses.

still, apparently the solar activity comes in 11 year cycles so there is hope for seeing a big storm again this year. and i don’t feel too bad in some sense that it was just one night, and that my parents will likely be able to plan a trip somewhere to see the aurora up close.

i also need to subscribe to npr. after google podcasts got dismantled (T^T) i stopped having a reliable podcast aggregator, and thus stopped listening to podcasts i used to regularly see. shortwave would have told me there was a big aurora event !

main realizations:

  1. the NASA map is just where the aurora is directly overhead. the aurora itself could still be seen for 600 miles+ distant. i wish i’d known that — if so i would’ve let my parents know.
  2. I hadn’t figured out where to find the news since twitter is really hard to use now. i found it finally — spaceweather.gov posts these cool infographics.

3. there are many types of auroras (well, each is unique but they have broad categories), and you can see the reportings as citizen science on aurorasaurus.org (though it seems to have died a bit from 4 or 5 years ago)

https://www.aurorasaurus.org/learn#common-shapes

4. the auroras are hard to predict. they don’t come from solar flares, which show up 8 mins later. they come from these coronal mass ejections — literally the sun farts out a ton of material out into space. so if NASA judges the angle it exits the moon, or the speed it goes, it can come a day early or a day late. or not show up much at all if it glances off the earth instead of hitting it head on.


“”Two main types of explosions occur on the sun: solar flares and coronal mass ejections. Unlike the energy and X-rays produced in a solar flare – which can reach Earth at the speed of light in eight minutes – coronal mass ejections are giant clouds of solar material that take one to three days to reach Earth. Once at Earth, these ejections, also called CMEs, can impact satellites in space or interfere with radio communications. During CME Week from Sept. 22 to 26, 2014, we explore different aspects of these giant eruptions that surge out from our closest star.””

5. there is an approximately 30 minute forecast since there is literally a space instrument orbiting earth that detects incoming matter. the exact forecast time varies depending on the speed of whatever is hitting the instrument.

Forecasting CME arrival times is by its nature difficult to do with high accuracy. Until an hour or so before a geomagnetic storm, there can be a window of uncertainty for when the CME arrives of plus or minus 12 hours—a whole day in total!

7. also spaceweather.com

8. spaceweather.gov has both a prediction and a current measurement, which can differ (see previous point)

The app is also really great!

9. the time for seeing auroras is the same everywhere — 2 hrs before and after midnight local time (!) still wrapping my head around how this works

10. kp1-10 is measuring same thing as G1-5, just different scales

11. solar wind speed (higher is better) and direction are important (apparently south is better than north?)

12. light pollution map app is also way better to use than websites which were super slow

13. peak times are listed in text on the spaceweather.gov site —

next time: bring a compass. at least from astrophotography class i knew to dress warmer than i think i need and bring a snack and water. brrr some cold nights on mit rooftops.
